Variability in chemical and microbiological profiles of long-ripened Caciocavallo cheeses

Five protected designation of origin (PDO) Caciocavallo Silano and 6 non-PDO Caciocavallo cheeses, ripened for 6mo and collected in the 5 Italian regions of the PDO area (Apulia, Basilicata, Calabria, Campania, and Molise, Italy), were studied to assess their physico-chemical (pH, acidity, moisture, fat, ash, protein, and free amino acid composition) and microbiological profiles. Analyses evidenced a certain fluctuation of previous parameters among samples regardless of the kind of cheese evaluated (PDO and non-PDO). The PCR-denaturing gradient gel electrophoresis analysis performed on the DNA directly extracted from cheeses gave different results, but a low number of bands was always observed. Only one band, corresponding to the species Streptococcus thermophilus, was detectable in 1 PDO and in 2 non-PDO cheese samples, whose free amino acid content was the lowest. Analyses were repeated on experimental Caciocavallo cheeses. Specifically, 2 productions were made, one mimicking the industrial technology (pasteurized milk and selected starter culture) and one the artisanal technology (raw milk and natural whey starter). Results obtained on experimental cheeses at 6mo of ripening showed that industrial samples had lower amounts of total free amino acids then the artisanal ones (1,188.2 vs. 7,523.67mg/100 g of dry matter). Moreover, the PCR-denaturing gradient gel electrophoresis analysis evidenced the sole presence of S. thermophilus in the case of the industrial technology. These data sustain the hypothesis that, out of 11 cheeses analyzed previously, 1 PDO Caciocavallo Silano and 2 non-PDO Caciocavallo cheeses were obtained with the industrial technology. These results could be of help in the discrimination of PDO products, taking into account that the PDO production regulation does not allow the milk pasteurization, nor the use of selected starters

Fluorescence in situ hybridisation detection of Lactobacillus plantarum group on olives to be used in natural fermentations

At present there are very few studies on the bacterial diversity of olives and on the importance of the microbial species for the fermentation of olives aimed to table olives production. Most of the authors report on the occurrence of Lactobacillus plantarum as principal member of these communities or at least as the species responsible for the fermentation. In this study, fluorescence in situ hybridisation (FISH) with 16S rRNA probes was used to evaluate the occurrence of L. plantarum in olives. A 18-bp oligonucleotide probe was used in FISH experiments to evaluate the specificity of detection among Lactobacillus species. The probe was tested against 30 Lactobacillus species and appeared to be specific for L. plantarum, L. paraplantarum and L. pentosus. The probe was then used to investigate the occurrence of these species in 25 samples of olives (cultivar “Leccino”) collected in Campania region (Southern Italy). The olives were washed in a saline solution and the suspensions were then analysed by FISH and observed by fluorescence microscopy. No hybridisation signal was detected in at least 30 fields of observation when the L. plantarum-specific probe was used, probably due to the low sensitivity of the FISH method. Olive samples were plated on Rogosa agar and about 40% of the samples did not give growth after 5 days. When colony growth was observed, bulk cells from Rogosa agar plates were collected and analysed by DNA extraction followed by 16S rDNA Polymerase chain reaction–denaturing gradient gel electrophoresis (PCR–DGGE). The different microbial species were identified by direct sequencing of DGGE bands. Leuconostoc pseudomesenteroides was the most frequently found species, occurring in more than 50% of the samples that had shown growth on Rogosa agar. The closest relatives of the species of the genera: Leuconostoc, Pediococcus, Pseudomonas and Raoultella were also identified suggesting that guided fermentation by using selected LAB starters is advisable for a safe and desired table olives production

Therapeutic, Prophylactic, and Functional Use of Probiotics: A Current Perspective

Probiotics are considered as the twenty-first century panpharmacon due to their competent remedial power to cure from gastrointestinal dysbiosis, systematic metabolic diseases, and genetic impairments up to complicated neurodegenerative disorders. They paved the way for an innovative managing of various severe diseases through palatable food products. The probiotics’ role as a “bio-therapy” increased their significance in food and medicine due to many competitive advantages over traditional treatment therapies. Their prophylactic and therapeutic potential has been assessed through hundreds of preclinical and clinical studies. In addition, the food industry employs probiotics as functional and nutraceutical ingredients to enhance the added value of food product in terms of increased health benefits. However, regardless of promising health-boosting effects, the probiotics’ efficacy still needs an in-depth understanding of systematic mechanisms and factors supporting the healthy action

Short communication: Identification and technological characterization of yeast strains isolated from samples of water buffalo Mozzarella cheese

Abstract Sixty yeast cultures were isolated from samples of water buffalo Mozzarella, a popular "pasta filata" cheese, originating on 16 farms located in the provinces of Salerno, Caserta, and Frosinone (Italy). Strains were identified by means of 5.8S internal transcribed spacer rDNA PCR-RFLP combined with 26S rRNA gene partial sequencing and characterized for their ability to exert biochemical properties of technological interest. The recorded dominance of fermenting yeasts such as the lactose-fermenting Kluyveromyces marxianus (38.3% of the total isolates) and the galactose-fermenting Saccharomyces cerevisiae (21.6% of the total isolates) suggests that these yeasts contribute to the organoleptic definition of the water buffalo Mozzarella. The speciographic analysis revealed the presence of 7 other species rarely or never reported in a dairy environment belonging to the genera Pichia and Candida , whose role in Mozzarella cheese organoleptic properties need to be further investigated

A informatização das bibliotecas escolares municipais de Florianópolis: percepção dos estagiários de Biblioteconomia.

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Educação. Curso de Biblioteconomia.Esta pesquisa visa analisar as percepções dos estudantes de Biblioteconomia que estagiaram em bibliotecas na Rede Municipal de Educação de Florianópolis e obtiveram contato com o processo de automação destas unidades, apresentando as opiniões expressas dos acadêmicos em relação ao grau satisfatório e insatisfatório acerca das funcionalidades processuais. Com um referencial teórico focado nas reflexões de autores que basearam seus estudos nos fenômenos sociais, buscou-se compreender as representações sociais existentes nas expressões dos participantes. O caráter da pesquisa deu-se através de método qualitativo, com a finalidade de compreender os aspectos sociais existentes nas opiniões obtidas. A coleta de dados concretizou-se através de entrevista, composta por questões abertas que buscaram exprimir estas informações dos respondentes. A técnica do Discurso do Sujeito Coletivo foi adotada para a análise dos dados obtidos mediante entrevista, com a finalidade de organizar estes discursos e transformá-los em um discurso único e representativo, que figurasse a opinião geral dos entrevistados. Os resultados apontam para as diferenças existentes entre as unidades de informação conhecidas pelos participantes, demonstrando a ausência de um padrão que nivele todas as unidades da Rede à mesma etapa do processo, tornando-o mais ágil e, conseqüentemente, mais útil. Os discursos evidenciaram, ainda, a diferença existente entre a teoria técnica do curso de Biblioteconomia e as práticas da mesma, decorrentes das adversidades existentes na rotina do profissional bibliotecário, adversidades estas que foram constatadas através da experiência do estágio curricular.This research intends to analyze the perceptions of the Librarianship's students that worked as trainees at libraries belonging to Florianópolis Municipal Education Web and had contact with the automation processes of such unities. The goal is to gather their opinions about how satisfying or unsatisfying the process functions are. With a theoretical referential focus on the views of authors that based their studies on social behaviors, it was of utmost importance to understand the social representations expressed in each participant's expressions. The research was performed using the Qualitative Method, aiming for understanding of the social aspects found in the various given opinions. The data collection was obtained via interviews, composed by open questions that were specifically meant to obtain said opinions from the subjects who were interviewed. The Collective Subject Discourse (CSD) was utilized for the analysis of the data that was obtained, with the end result of organizing each interview and modeling the information into a single representative speech that displayed the overall main opinions of each participating individual. The results of the study pointed to existing differences between the information known by each individual student, showing a lack of pattern that could level all participating units. The research will help allow the Web to function as a whole, which the intended result being a more agile and consequently more useful process that's improved overall. The discourse also brought to light the existing differences between the technical theory of the Librarianship course and the practical techniques that it utilizes; adversities that were proven through the Curricular experience as a whole.Este estudio pretende analizar las percepciones de los estudiantes de Bibliotecologia que trabajaron como pasantes en bibliotecas de la Red Municipal de Educación de Florianópolis y obtuvieron contacto con el proceso de automatización de estas unidades, presentando las opiniones expresas de los académicos en relación al grado satisfactório e insatisfatório acerca de las funcionalidades procesuales.

Development of a Wet-Granulated Sourdough Multiple Starter for Direct Use

The search for sourdough starters for the direct production of baked goods with all the advantages of biological sourdough fermentation is still a crucial issue. In this study, 43 Lactic Acid Bacteria strains isolated from mature sourdoughs were evaluated for features of technological interest and tested for fermentation ability. Three microbial combinations were selected and used to produce bread. Based on GC-MS and sensory analysis, bread made by using the three combinations of strains was characterized by a more complex aroma profile with the prevalence of VOCs typical of sourdough bread. To set up the best way to keep microbial viability upon drying, the three combinations were subject to freeze-drying and wet granulation, with the latter being used for the first time for food starters’ stabilization. Wet granulation ensured optimal strains’ viability. Surprisingly, the height attained by mature sourdoughs when inoculated with wet granulated starters was constantly higher than the height reached by sourdoughs made with the same starters as fresh cells. The microbial combination E75-B72 exhibited the best performances and may represent a starter able to ensure sourdough bread production in 16 h of fermentation at 28 °C

Sociedad y cuidado desde la perspectiva de niños sin cuidado parental (NSCP).: Society and care from the perspective of children without parental care.

Objective: Understand the meanings given by children without parental care to living conditions, relationships established and how they negotiate or recreate their situation in the places where they grow, recognizing them as necessary interlocutors for the analysis of the circumstances of their place of growth.   Materials and Methods: Multi-sited research for the transitory character of their life, it is epistemologically based on perspectivism, addressing thirty street children, thirty-five children in educational institutions and twenty-one in child protection centres in cities and municipalities within the industrial corridor of Boyacá, Colombia. Qualitative strategies such as life stories, interviews (occasionally made by the participant children) were implemented for this research; also, participative strategies such as participant observation and workshops. Results: Relationships with neighbors, close relatives or friends, government officials or teachers who practice transitory care actions as an exception to the general rule of indifference, acquire for the participants other feelings regarding possibilities of emotional ties that, however, are lost due to personal or social reasons and are not favorable for them, generating open questions about the role society could play as co-responsible of their growth. Conclusions: The knowledge based on experience of children without parental care was fundamental to understand that the construction of society has abandoned care as the main focus in the growth and the training of human beings, and to find other ways of interpreting childhood regarding social status.Objetivo: Comprender los significados que otorgan niños y niñas sin cuidado parental, a las condiciones de vida, relaciones que establecen y formas como negocian o recrean su situación en los lugares en que crecen, reconociéndolos como interlocutores necesarios para el análisis de las circunstancias en que tiene lugar su crecimiento.  Materiales y métodos: Investigación multisituada por el carácter transitorio de sus vidas, se fundamenta epistemológicamente en el perspectivismo, abordando treinta niños y niñas en contextos de calle,  treinta y cinco niños y niñas en instituciones educativas y veintiuno en centros de protección, en ciudades y municipios que conforman el corredor industrial de Boyacá.  Para ello se implementaron estrategias cualitativas como relatos de vida, entrevistas en ocasiones realizadas por los niños y niñas participantes; también estrategias participativas tales como observación participante y talleres. Resultados: Las relaciones con vecinos o cercanos, funcionarios del estado y maestros, quienes ejercen acciones transitorias de cuidado como una excepción a la regla general de indiferencia, adquieren para los participantesotros sentidos en cuanto a posibilidades de vínculos afectivos que, no obstante, se pierden por razones personales o sociales que no los favorecen, generando interrogantes sobre el papel que podría desempeñar la sociedad como corresponsable de su crecimiento. Conclusiones: El conocimiento basado en la experiencia de niños y niñas sin cuidado parental fue fundamental para comprender que la construcción de sociedad ha ido abandonando el cuidado como su eje central en el crecimiento y la formación de los seres humanos y para encontrar otras formas de interpretar la niñez en cuanto categoría social

Depresión y factores asociados en embarazadas durante la pandemia Covid-19 Lambayeque, 2020

Objetivo: Describir los factores de asociados para depresión en mujeres embarazadas durante la pandemia COVID-19 en el Centro de Salud José Olaya Chiclayo-Lambayeque, 2020. Material y métodos: Se evaluó a gestantes atendidas en el Centro de Salud José Olaya Chiclayo-Lambayeque durante julio-agosto del 2020. Se les contactó durante sus sesiones de profilaxis, previo consentimiento informado, la entrevista se realizó por medio de sus redes sociales, donde se le aplicaron tres encuestas: la escala de depresión de Edimburgo (EPDS), un cuestionario de factores asociados para depresión y una de nivel socioeconómico. Estudio de diseño observacional, tipo descriptivo. Muestreo probabilístico sistemático. Resultados: La prevalencia de depresión en embarazadas fue del 34,5%; los factores asociados fueron antecedente de aborto (RP = 3,95), recibir insultos por parte de familiares o pareja (RP =2.48) y pasar por una experiencia estresante (RP =4,45). Aquellas que tienen un antecedente de aborto presentan prevalencia de depresión 3,95 veces mayor que aquellos que no presentaron dicho antecedente, las gestantes que recibieron insultos de algún familiar o pareja presentaron una prevalencia de depresión 2,48 veces. Conclusión: La prevalencia de depresión en gestantes del Centro de Salud José Olaya fue del 34,5%, esta prevalencia es similar a la encontrada en otros estudios en épocas de pandemia, y es mayor a la reportada en trabajos anteriores a la pandemia, al igual que en otras investigaciones
