Proteases ácidas pertencem a um importante grupo de enzimas industriais produzidas por fungos filamentosos, com aplicações na indústria de alimentos, de couro, farmacêutica e de cosméticos. O objetivo principal deste trabalho foi avaliar a produção de proteases ácidas extracelulares de fungos filamentosos isolados do solo do cerrado do centro-oeste brasileiro. Inicialmente, foi realizada uma triagem para avaliar a capacidade de 17 linhagens de fungos quanto à produção de protease em meio de cultura contendo Agar-leite. O fungo Aspergillus foetidus foi selecionado como melhor produtor de protea

Abstract:
Developing microbial systems capable of converting low cost lipids into value added products depends on the ability to acquire substrates from the growth media. Saccharomyces cerevisiae can acquire free fatty acids from the growth media and a portion of these lipids can be converted into new lipid products. However, they cannot acquire complex lipids from the growth media unless a nonspecific lipase is included. To circumvent lipase addition, we are genetically engineering S. cerevisiae to secrete a lipase into the growth media. We selected the LIP2 gene from Yarrowia lipolytica, which encodes

A demanda por antioxidantes naturais vem aumentando devido à toxicidade de alguns antioxidantes sintéticos. Estudos vêm identificando antioxidantes de origem natural, como a proteína da soja, que é capaz de contribuir na melhoria de propriedades funcionais e biológicas de alimentos. A hidrólise enzimática da proteína de soja aumenta sua atividade antioxidante, assim como a capacidade emulsificante e a capacidade de formação de espuma. O objetivo deste trabalho foi o estudo da hidrólise da proteína de soja através de uma protease produzida por Chryseobacterium sp., a verificação da capacidade a

Pseudomonas fragi ATCC 4973 was grown in trypticase soy broth (TSB), on a trypticase soy broth + 1.5% agar (TSA) surface, and in a defined citrate broth. The citrate broth contained glutamine as the sole nitrogen source, Pseudomonas fragi grown in TSB started proteinase production at 24 h, during the late logarithmic early stationary growth phase. Pseudomonas fragi grown on TSA surfaces initiated proteinase production at 4 h, 20 hours earlier than in liquid medium. Electron micrographs of P. fragi grown on TSA revealed extracellular vesicles ca. 20 nm in diameter "blebbing" off the surface of

Abstract:
In this study, the aim was to investigate the effects of pH on therapeutically important protein, recombinant human growth hormone (rhGH), production by Pichia pastoris considering the expression levels of regulatory genes. In this frame, firstly the host microorganism was selected between two different methanol utilization phenotypes of P. pastoris, Mut+ and MutS on media containing glycerol/methanol or sorbitol/methanol. The highest rhGH production, 120 g L-1, and hGH gene expression, 9.84x109 copies mg-1 CDW, were achieved in the medium containing 30 g L-1 sorbitol and 1% (v/v) methanol by
