During composting processes, the degradation of organic waste is accomplished and driven by a succession of microbial populations exhibiting a broad range of functional competencies. A total of 183 bacteria, isolated from a composting process, were evaluated for cellulase activity at different temperatures (37, 50, 60, and 70°C) and pH values. Out of the 22 isolates that showed activity, isolate 380 showed the highest cellulase activity. Its ability to produce cellulase was evaluated in culture medium supplemented with carboxymethyl cellulose, microcrystalline cellulose, wheat straw, and rice husk. The culture medium supplemented with carboxymethyl cellulose induced higher enzyme activity after 6 hours of incubation (0.12 UEA mL -1 min -1 ). For wheat straw and rice husk, the results were 0.08 UEA mL -1 min -1 for both, while for microcrystalline cellulose, 0.04 UEA mL -1 min -1 were observed. The highest carboxymethyl cellulase activity was observed at 60°C (0.14 UEA mL -1 min -1 ) for both crude and partially purified enzyme after 30 and 120 min of incubation, respectively. Alkalinization of the medium was observed during cultivation in all substrates. The cellulase had a molecular mass of 20 kDa determined by SDS-Page. Isolate 380 was identified as Bacillus licheniformis. This work provides a basis for further studies on composting optimization.

“…and relatively inexpensive cultivation techniques (Chang & Miles, 2004). Therefore, these interesting attributes make it an excellent option for cultivation in Brazil, particularly in regions with warmer climates (Dias, 2010). It's simple cultivation technique allows that agro wastes may be used to produce a highly nutritious food and of high commercial value (Mane et al, 2007).…”

Banana stalks and Bahia grass were utilized as basic starting materials for the production of the mushroom Pleurotus sajor-caju. Banana stalks were combined with other waste or supplement products (wheat bran, coast-cross hay, bean straw and cotton textile mill) to obtain different nitrogen concentrations. Since Bahia grass is relatively rich in protein, it was combined with other substrates (banana stalk, coast-cross hay and bean straw) to maintain a substrate nitrogen concentration of about 1.5%. Banana stalks and Bahia grass were both more efficient in the production of the mushroom P. sajor-caju when utilized without the addition of other substrates, with biological efficiencies of 74.4% and 74.12%, respectively. When combined with other substrates or grasses, there was a drop in biological efficiency, independent of the concentration of nitrogen. Furthermore, the addition of protein-rich waste to banana stalks resulted in a decrease or absence of fructification, which indicates that high concentrations of nitrogen in the cultivation substrate may hinder the cultivation of this mushroom. On the other hand, results reveal that the ideal concentration of nitrogen may depend on other physicochemical factors and these factors may determine the success in cultivating P. sajor-caju. Therefore, we conclude that P. sajor-caju may be cultivated on banana stalk and Bahia grass as pure substrates, not being necessary their supplementation or combine them with another substrates.

“…Muitos estudos têm destacado a possibilidade de cultivar em pequena escala e com poucos investimentos fungos deste gênero, mas pesquisas com novas espécies de Agaricus, com novas raças melhor adaptadas, novas téc-nicas de cultivo adaptadas à realidade regional e técnicas mais baratas de cultivo ainda têm sido pouco trabalhadas (Dias, 2010;Figueirêdo e Dias, 2014).…”

“…De acordo com Dias (2010), a produção de cogumelos representa, em termos comerciais, uma das maiores taxas de retorno por unidade de área, podendo gerar lucro de até 150% sobre o capital investido ao final do ciclo produtivo. O autor destaca que a expansão desta cultura no país depende de pesquisas objetivando maior produtividade, controle de qualidade, aproveitamento de matéria orgânica disponível, produção a baixo custo e exportação.…”

ResumoO gênero Agaricus é um dos mais importantes entre os cogumelos Agaricales, pela produção comercial de várias de suas espécies comestíveis e medicinais. Com vários problemas taxonômicos envolvendo a grande diversidade deste gênero, também cultivado no Brasil, não há, ainda, um trabalho envolvendo as espécies ocorrentes neste país. Levantando dados da literatura e revisando material depositado em herbários, procedeu--se à elaboração de lista e descrições para as espécies citadas. Chave e ilustrações são apresentadas para facilitar a diferenciação das 32 espécies confirmadas para o Brasil.Palavras-chave: lista de espécies, chave dicotômica, taxonomia, distribuição. AbstractThe genus Agaricus is one of the most important among Agaricales, especially by its commercial use as edible and medicinal mushrooms. With lots of taxonomical problems since it is very diverse, there is no work concerning the Brazilian species known up to now in Brazil. By searching bibliographical data and reviewing herbarium collections, we finished a list of 32 species known as occurring in the area. Key and illustrations are provided for each species.Keywords: species list, identification keys, taxonomy, distribution. Introdução O gênero Agaricus L. ex. Fr. pertence à família Agaricaceae (Agaricales, Basidiomycota), apresentando a seguinte combinação de características: há-bito pluteoide ou também chamado de agaricoide, com píleo carnoso, de superfície lisa, fibrilosa, esquamulosa a escamosa, ou com espinhos piramidais, às vezes com o centro (disco central) íntegro e metade marginal rompendo-se para formar escamas; forma muito variável, mas em geral convexo a hemisférico. Lamelas livres e remotas, mas sem colário, brancas a rosadas mas escurecendo somente a partir da maturação dos esporos; estipe central, às vezes com base bulbosa, raro com volva; véu membranoso ou cortinoide presente, às vezes rudimentar ou fugaz, desaparecendo rapidamente ou permanecendo como escamas na superfície; volva geralmente ausente; esporada variando de marrom-púrpura até marrom-escuro ou sépia. Esporos lisos, amarronzados sob o microscópio, de parede grossa, com (às vezes, rudimentares como em A. cam-
