Resumo: The majority of Brazilian arable soils shows P deficiency, due to the fact that most of this element in the soil is unavailable for the plant absorption, for this and other reasons, the ability of filamentous fungi to solubilize P from various sources, insoluble, organic and inorganic, has been considered a desirable feature for several uses. The aim of this study was to characterize the production of phytase mycobiota in soil located in Cerrado in two seasons, under dry and rainy seasons, and also characterize abiotic factors in this biome in order to verify the existence of correlations between the quantitative and qualitative aspects of their mycobiotas in these conditions. The samples were collected from eight forest fragments twice, two soil depths (0-5 and 5-10 cm) and litter layer to quantify mycobiota and the evaluation of phytase production. In the collection carried out in the rainy season, the total number of phytase producing fungi was lower, but the number of Aspergillus section Nigri producers of phytase was greater. In the dry season the number of phytase producing fungi belonging to the genus Penicillium was higher. The year season´s factor alters quantitatively and qualitatively the phytase producer mycobiota. It was concluded that the soils are potentially exploitable in relation to obtaining phosphorus solubilizing fungi, and the dry season is more propitiate to the achievement of these fungi.

Neste contexto, a habilidade dos fungos filamentosos em solubilizar o P de várias fontes, sejam estas, insolúveis, orgânicas e/ou inorgânicas, tem sido considerada uma característica de destacada importância. O objetivo do presente estudo foi caracterizar a micobiota produtora de fitase no Bioma Cerrado, bem como, apresentar uma caracterização dos fatores abióticos do presente bioma e as possíveis correlações com a micobiota encontrada. As amostras foram coletadas de oito fragmentos florestais, em duas épocas, duas profundidades do solo (0-5 e 5-10 cm) e na camada de serapilheira para a quantificação da micobiota e avaliação da produção de fitase. As coletas foram realizadas em duas épocas, sendo uma na época chuvosa e outra na época seca. Na coleta da época chuvosa, o número total de fungos produtores de fitase foi menor, mas o número de Aspergillus seção Nigri produtores de fitase foi maior. Na época seca, o número de fungos produtores de fitase pertencentes ao gênero Penicillium foi maior. O fator época do ano alterou qualitativamente e quantitativamente a micobiota produtora de fitase. Concluiu-se que os solos do Bioma Cerrado são potencialmente exploráveis para a obtenção de fungos solubilizadores de P, sendo a época seca do ano a mais propícia para este fim.Universidade Federal de Santa Maria2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1558610.5902/1980509815586Ciência Florestal; Vol. 29 No. 3 (2019); 1270-1281Ciência Florestal; v. 29 n. 3 (2019); 1270-12811980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/15586/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessDonato, Alexandre deConto, Tiago deMaia, Tatiana FariaPareira, Marcos GervasioFraga, Marcelo Elias2019-10-01T13:06:32Zoai:ojs.pkp.sfu.ca:article/15586Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-10-01T13:06:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
