Resumo: | Edible mushrooms are renowned for their nutritional and medicinal properties and are thus of considerable commercial importance. Mushroom production depends on the chemical composition of the basic substrates and additional supplements employed in the compost as well as on the method of composting. In order to minimise the cost of mushroom production, considerable interest has been shown in the use of agro-industrial residues in the preparation of alternative compost mixtures. However, the interaction of the natural microbiota present in agricultural residues during the composting process greatly influences the subsequent colonisation by the mushroom. The aim of the present study was to isolate and identify the microbiota present in a sugar cane bagasse and coast-cross straw compost prepared for the production of Agaricus brasilienses. Composting lasted for 14 days, during which time the substrates and additives were mixed every 2 days, and this was followed by a two-step steam pasteurisation (55 - 65ºC; 15 h each step). Bacteria, (mainly Bacillus and Paenibacillus spp. and members of the Enterobacteriaceae) were the predominant micro-organisms present throughout the composting process with an average population density of 3 x 108 CFU/g. Actinomycetes, and especially members of the genus Streptomyces, were well represented with a population density of 2 - 3 x 108 CFU/g. The filamentous fungi, however, exhibited much lower population densities and were less diverse than the other micro-organisms, although Aspergillus fumigatus was present during the whole composting process and after pasteurisation |

A produção de cogumelos depende da composição química dos substratos básicos, dos suplementos utilizados e da preparação do composto no qual o fungo será cultivado. Considerando-se que os custos de produção precisam ser minimizados, os resíduos agroindustriais representam uma fonte alternativa e econômica para a preparação do composto. A interação da microbiota natural dos resíduos agrícolas durante o processo de compostagem influencia a subseqüente colonização do cogumelo. Visando-se a produção de A. brasiliensis, o presente trabalho objetivou isolar e identificar a microbiota presente no composto preparado a partir de bagaço de cana e capim coast-cross. O processo de compostagem durou 14 dias com reviragens da pilha a cada dois dias, o qual foi seguido de pasteurização (55 65 ºC) em duas fases por 15 h cada. As bactérias (principalmente Bacillus, Paenibacillus e espécies da família Enterobacteriaceae) foram os microrganismos predominantes durante todo o processo com uma densidade populacional média de 3.0 x 108 UFC/g. Os actinomicetos, principalmente os do gênero Streptomyces, estiveram bem representados, com uma densidade populacional de 2.0 a 3.0 x 108 UFC/g. Os fungos filamentosos foi a classe de microrganismos com menor densidade populacional e menor diversidade, embora a espécie Aspergillus fumigatus esteve presente durante todo o processo de compostagem e também após a pasteurização do composto.Sociedade Brasileira de Microbiologia2017-08-18T13:21:17Z2017-08-18T13:21:17Z2009-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, C.
