Physicochemical characterization of the brown pigment produced by Azospirillum brasilense HM053 using tryptophan as precursor.

Microorganisms are known to be a promising source of biopigments because they are easy to obtain, can be produced on a commercial scale, and are environmentally friendly. Therefore, the aim of this work was to characterize a brown pigment (BP) produced by HM053 in NFbHPN-lactate medium. The BP was extracted from the pellet (BPP) or supernatant (BPS), in the presence (BPPTrp, BPSTrp) or absence (BPPw, BPSw) of tryptophan (Trp). The UV-vis results were similar among all BP samples and compared with commercial melanin used as a standard, and the maximum absorption was observed around 200–220 nm. FTIR spectra showed that BP and commercial melanin had slight differences, with a small band between 3000–2840 cm− 1, related to C-H in the CH2 and CH3 aliphatic groups, which is not observed in the commercial melanin. Between BPP and BPS showed a different structure with bands in the region 1230–1070 cm− 1 related to groups C-O. The thermogravimetric curves for BPSw and BPSTrp showed similar behavior, with 4 stages of mass loss. The similarity between BPPw and BPPTrp with 2 stages of mass loss was also observed. Scanning electron microscopy results showed morphological differences between BPP and BPS, where BPP had a physical structure more homogeneous and a regular flat surface, while the BPS physical structure did not seem homogeneous and the surface was uneven with some spherical structures as commercial melanin

Água de beber: a filtração doméstica e a difusão do filtro de água em São Paulo

This work studies the advent and diffusion of water filter usage in São Paulo State, during the 20th Century. The water filter, a set of two terracotta vessels equipped with a filtering device, was a product of the ceramics industry, one of the first to be developed in São Paulo. This research shows that in São Paulo at the end of 19th and beginning of 20th Centuries, with the growth of cities and rapid urbanisation, a concern about the quality of water increased due to serious public health hazards, mainly epidemics caused by the consumption of unhealthy drinking water. Despite the existence of an incipient market of domestic equipment for water filtration, these were imported and of limited usage. From the 1910's, ceramics companies, owned by Portuguese and Italian immigrants, started installing filtering devices in terracotta vessels, launching the water filter set. It caught on and became the main domestic filtering equipment after the 1930's, when several companies specialized in this kind of product and started catering for the national market, such as Filtros Salus (from São Paulo city), Pozzani (Jundiaí) and Stéfani (Jaboticabal). Studying the advent and diffusion of the water filter entails knowledge about one of the first consumer goods of the Brazilian industry and, at the same time, knowledge about the history of the ways in which the Brazilian population obtained water to drink.Este artigo trata do processo de surgimento e difusão do uso do filtro de água no Estado de São Paulo, ao longo do século XX. O filtro de água, conjunto de dois recipientes de argila equipado com vela filtrante, é um produto da indústria cerâmica, uma das primeiras a se desenvolver em São Paulo. A pesquisa mostra que, em São Paulo, no final do século XIX e início do XX, com o aumento da urbanização e o crescimento das cidades, a preocupação com a qualidade da água que se consumia ganhou importância em virtude de graves problemas de saúde pública principalmente epidemias causadas por águas impróprias para beber. Embora já existisse um incipiente mercado de equipamentos domésticos de filtração da água, eles eram ainda importados e de uso restrito. A partir da década de 1910, empresas cerâmicas, de imigrantes portugueses e italianos, passaram a acoplar velas filtrantes a recipientes de argila, dando origem ao filtro de água. Depois dos anos de 1930, o filtro difundiu-se e tornou-se o principal equipamento de filtração doméstica, quando diversas empresas, como Filtros Salus (São Paulo-SP), Pozzani (Jundiaí-SP) e Stéfani (Jaboticabal-SP), especializaram-se nesse produto e passaram a atender ao mercado nacional. Estudar o surgimento e a difusão do filtro de água significa conhecer um dos primeiros bens de consumo da indústria brasileira e, ao mesmo tempo, a história de como a população obtém água para beber

Vestígios indígenas na cartografia do sertão da América portuguesa

During the first three centuries of colonization of Portuguese America, indigenous cartography helped the outlanders to decipher the space that they conventionally named sertão (backcountry). The colonizers in the Captaincy of São Paulo (expeditions, soldiers, settlers, bureaucrats, merchants, and adventurers) mapped out the hinterland with utmost care. However, because the territory was a colony, such agents reorganized that space and classified the ethnic groups into distinct, fixed and homogenous categories. As the Portuguese Crown moved ahead with its conquest, the indigenous groups were gradually wiped out from the maps and their territories expropriated.Nos três primeiros séculos da colonização da América portuguesa, a cartografia indígena auxiliou no processo de decodificação do espaço convencionalmente chamado "sertão" pelos adventícios. Agentes de colonização da capitania de São Paulo (bandeirantes, soldados, povoadores, burocratas, comerciantes e aventureiros) mapearam cuidadosamente os territórios interiores. A situação colonial, entretanto, impôs uma nova orientação do espaço, bem como classificou os grupos étnicos em categorias distintas, fixas e homogêneas. Nesse processo de conquista da Coroa portuguesa, os grupos indígenas foram gradativamente eclipsados dos mapas, e seus territórios, expropriados

Inactive X chromosome-specific histone H3 modifications and CpG hypomethylation flank a chromatin boundary between an X-inactivated and an escape gene

In mammals, the dosage compensation of sex chromosomes between males and females is achieved by transcriptional inactivation of one of the two X chromosomes in females. However, a number of genes escape X-inactivation in humans. It remains poorly understood how the transcriptional activity of these ‘escape genes’ is maintained despite the chromosome-wide heterochromatin formation. To address this question, we analyzed a putative chromatin boundary between the inactivated RBM10 and an escape gene, UBA1/UBE1. Chromatin immunoprecipitation revealed that trimethylated histone H3 lysine 9 and H4 lysine 20 were enriched in the last exon through the proximal downstream region of RBM10, but were remarkably diminished at ∼2 kb upstream of the UBA1 transcription start site. Whereas RNA polymerase II was not loaded onto the intergenic region, CTCF (CCCTC binding factor) was enriched around the boundary, where some CpG sites were hypomethylated specifically on inactive X. These findings suggest that local DNA hypomethylation and CTCF binding are involved in the formation of a chromatin boundary, which protects the UBA1 escape gene against the chromosome-wide transcriptional silencing
