Resumo: Few studies have been done to determine Agaricus brasiliensis Wasser et al. (A. blazei; A. subrufescens) basic mycelial growth characteristics on axenic cultivation. This study aimed to determine the optimal temperature and initial pH for mycelial growth of A. brasiliensis on malt extract agar medium to develop axenic cultivation techniques. Studied initial pH values for mycelial growth were adjusted to 3.0, 4.0, 5.0, 5.5, with HCl, 6.0, 7.0, 8.0, with NaOH, and again 7.0 and 8.0, with CaCO3. Studied temperatures for mycelial growth were 22 ºC, 25 ºC, 28 ºC, 31 ºC and 34 ºC. It was concluded that A. brasiliensis can grow in axenic cultivation at temperature range from 22 oC to 34 ºC, with optimal temperature range from 28 oC to 31 ºC and optimal temperature value of 30.5 ºC ± 0.3 ºC. It also grows in initial pH range from 4.0 to 7.0, adjusted with HCl or NaOH but not CaCO3, with optimal initial pH range from 5.5 to 6.0 and optimal initial pH value of 5.56 ± 0.05. Mycelial growth is inhibited with pH of 3.0 or lower, 8.0 or higher, or when CaCO3 is used to adjust pH in the substratum to 7.0 or higher.

(A. blazei, A. subrufescens). O objetivo deste trabalho foi determinar a faixa ótima de temperatura e pH para o crescimento micelial, em agar-extrato-de-malte, de A. brasiliensis, visando o desenvolvimento de técnicas de cultivo axênica. Os valores de pH estudados foram 3,0, 4,0, 5,0 e 5,5, ajustados com HCl, 6,0, 7,0 e 8,0, ajustados com NaOH, e 7,0 e 8,0, ajustados com CaCO3. As temperaturas de crescimento estudadas foram 22 ºC; 25 ºC; 28 ºC; 31 ºC e 34 oC. Concluiu-se que A. brasiliensis cresce em uma faixa de temperatura ótima de 28 oC a 31 ºC, com valor ótimo de temperatura de 30,5 ºC ± 0,3 ºC. A faixa de pH inicial ótimo no substrato é de 5,5 a 6,0 e o valor de pH inicial ótimo é de 5,56 ± 0,05. O crescimento do micélio é inibido com pH de 3,0 ou inferior, 8,0 ou superior, ou quando CaCO3 é utilizado para ajuste do pH para 7,0 ou superior.UEL2008-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/281810.5433/1679-0359.2008v29n2p307Semina: Ciências Agrárias; Vol. 29 No. 2 (2008); 307-312Semina: Ciências Agrárias; v. 29 n. 2 (2008); 307-3121679-03591676-546Xreponame:Semina.
