Development of Lactococcus lactis Biosensors for Detection of Diacetyl

Some secondary metabolites of fermentative bacteria are desired compounds for the food industry. Examples of these compounds are diacetyl and acetaldehyde, which are produced by species of the lactic acid bacteria (LAB) family. Diacetyl is an aromatic compound, giving the buttery flavor associated with dairy products, and acetaldehyde is the compound responsible for the yogurt flavor and aroma. The quantification of these compounds in food matrices is a laborious task that involves sample preparation and specific analytical methods. The ability of bacteria to naturally sense metabolites has successfully been exploited to develop biosensors that facilitate the identification and quantification of certain metabolites (Mahr and Frunzke, 2016). The presence of a specific metabolite is sensed by the biosensors, and it is subsequently translated into the expression of one or more reporter genes. In this study we aimed to develop fluorescence-based biosensors to detect diacetyl and acetaldehyde. Since the metabolic pathways for production and degradation of these compounds are present in Lactococcus lactis, the sensing mechanisms in this bacterium are expected. Thus, we identified diacetyl and acetaldehyde responsive promoters by performing transcriptome analyses in L. lactis. The characterization of the biosensors showed their response to the presence of these compounds, and a further analysis of the diacetyl-biosensors (its dynamics and orthogonality) was performed. Moreover, we attempted to produce natural diacetyl from producer strains, namely L. lactis subsp. lactis biovar diacetylactis, to benchmark the performance of our biosensors. The diacetyl-biosensors responded linearly to the amounts of diacetyl obtained in the bacterial supernatants, i.e., the increases in GFP expression were proportional to the amounts of diacetyl present in the supernatants of L. lactis subsp. lactis biovar diacetylactis MR3-T7 strain. The biosensors developed in this study may eventually be used to engineer strains or pathways for increased diacetyl and acetaldehyde production, and may facilitate the detection of these metabolites in complex food matrices

Maturity model for assessing digitalization process of construction industry companies

The construction industry is on the verge of large–scale changes as Industry 4.0 is preparing industrial enterprises for serious challenges. Digital transformation can bring significant changes in all areas of enterprise activity. Maturity models are usually used to assess the current situation and measure the digital maturity of an organization. The authors’ four-stage model of digital maturity assessment for construction industry companies has been proposed. When developing the model, it had been decided to move away from general assessments and use specific changes that would occur at construction industry companies in the process of digital transformation as an assessment tool. The model contains fifteen assessment factors, changes of which at various stages are indicators of digital maturity. The proposed model contains a detailed description of the four stages of digital maturity, therefore it can serve not only to assess the digital maturity of industrial enterprises in the construction industry, but can also be used to indicate the goals planned to be achieved in the future as part of digital transformation, in strategies or business models of enterprises. A distinctive feature of the model is evaluation factors reflecting the degree of integration of the digital environment of industrial enterprises with BIM models of construction organizations

Religion as Source Domain of Metaphors in World War II Media Discourse

The article studies the English-language media discourses of the World War II period from a retrospective point of view. The aim is to identify the patterns of modeling the images of war and peace in British, American and Australian media discourses. The definition of military media discourse as an institutional form of communication is proposed, its essential characteristics are highlighted. The source of the material was the authoritative digitized archives of the UK, the USA and Australia. The material was extracted using corpus linguistics tools. The qualitative analysis was carried out within the framework of the cognitive-discourse methodology using the method of metaphorical modeling. The object of the research is the dominant metaphor used when representing the images of war and peace in the three discourses. The authors show common and specific features of the use of the religious metaphor, conditioned by cultural and extra-linguistic factors, and conclude that the religious metaphor places war and peace at different poles of the scale of values and actualizes the binary axiological opposition “good — evil”, “light — darkness”

Formation of an intelligent control system in the field of electric power industry based on the technological development of power supply components

The relevance of the paper is determined by the fact that the digital transformation of the country is recognized as one of the priorities for the economic development of the state. It is necessary to remove barriers for the digital transformation in the most promising areas of production and life by stimulating the introduction of digital technologies and attracting investments, overcoming the digital divide, deepening cooperation between states in the digital sphere and developing the country's digital innovation infrastructure. The novelty of the study is determined by the fact that the transition to a new level of digital functioning of electric systems is possible in the context of formation of a smart energy supply system and the introduction of modern information technologies. The authors show that the introduction of new energy meters is the basis for creating an innovative infrastructure of the fuel and energy complex of the national economy. The authors believe that this is the basis for the transition to a new level of energy supply and the introduction of new economic mechanisms for demand management and further development of energy markets. This in turn contributes to the integration of energy systems of different countries.

It is proposed to determine the needs of industry in sustainable energy supply

Tapping into rhythm generation circuitry in humans during simulated weightlessness conditions

An ability to produce rhythmic activity is ubiquitous for locomotor pattern generation and modulation. The role that the rhythmogenesis capacity of the spinal cord plays in injured populations has become an area of interest and systematic investigation among researchers in recent years, despite its importance being long recognized by neurophysiologists and clinicians. Given that each individual interneuron, as a rule, receives a broad convergence of various supraspinal and sensory inputs and may contribute to a vast repertoire of motor actions, the importance of assessing the functional state of the spinal locomotor circuits becomes increasingly evident. Air-stepping can be used as a unique and important model for investigating human rhythmogenesis since its manifestation is largely facilitated by a reduction of external resistance. This article aims to provide a review on current issues related to the ‘locomotor’ state and interactions between spinal and supraspinal influences on the central pattern generator circuitry in humans, which may be important for developing gait rehabilitation strategies in individuals with spinal cord and brain injuries

Riboflavin Biosynthesis and Overproduction by a Derivative of the Human Gut Commensal Bifidobacterium longum subsp. infantis ATCC 15697

Riboflavin or vitamin B2 is the precursor of the essential coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). Despite increased interest in microbial synthesis of this water-soluble vitamin, the metabolic pathway for riboflavin biosynthesis has been characterized in just a handful of bacteria. Here, comparative genome analysis identified the genes involved in the de novo biosynthetic pathway of riboflavin in certain bifidobacterial species, including the human gut commensal Bifidobacterium longum subsp. infantis (B. infantis) ATCC 15697. Using comparative genomics and phylogenomic analysis, we investigated the evolutionary acquisition route of the riboflavin biosynthesis or rib gene cluster in Bifidobacterium and the distribution of riboflavin biosynthesis-associated genes across the genus. Using B. infantis ATCC 15697 as model organism for this pathway, we isolated spontaneous riboflavin overproducers, which had lost transcriptional regulation of the genes required for riboflavin biosynthesis. Among them, one mutant was shown to allow riboflavin release into the medium to a concentration of 60.8 ng mL–1. This mutant increased vitamin B2 concentration in a fecal fermentation system, thus providing promising data for application of this isolate as a functional food ingredient
