Relative viability (%) of Metarhizium robertsii ARSEF 2575 produced in parboiled rice supplemented or unsupplemented with riboflavin and sodium nitrate after exposure to heat stress. Rice was washed with Tween 80® (0.01% v/v) after twenty days of solid fermentation. The groups evaluated were: A: Crude extract produced in supplemented medium; B: Conidia produced in supplemented medium; C: Crude extract produced in unsupplemented medium; D: Conidia produced in unsupplemented medium. Samples of each group were exposed to 45 ± 0.2 °C and at each 1 h of exposure an aliquot was inoculated in culture medium for germination analysis. All exposure times were compared to the 0 h of heat exposure. *P < 0.05 and **P < 0.01 according to Tukey’s Test
