“…From the literature, it is clear that the carbon and nitrogen status and the C : N ratio, in addition to the ambient pH, are the main nutritional factors influencing conidiation in Trichoderma (Aube & Gagnon, 1969;Bastos, 2001;Brian & Hemming, 1950;Friedl et al, 2008;Gao et al, 2007;Jackson et al, 1991;Kredics et al, 2004;Lewis & Papavizas, 1983;Monga, 2001;Steyaert et al, 2010b, c).…”

“…Aube & Gagnon (1969) observed that conidiation decreases with increasing nitrogen levels, and Jackson et al (1991) found that mycelial biomass increases significantly as the nitrogen levels decrease. This concept was investigated further by Gao et al (2007), who demonstrated an interactive effect on conidiation in T. viride between the level of carbon and the C : N ratio. Alone or in combination with different amounts of nitrogen, 6 g l 21 carbon (sucrose) produced the highest quantity of conidia.…”

“…This result demonstrated that the optimal C:N ratio for spore production of B. bassiana BNBCRC was at 29.63 in the BHE-based liquid culture (with the initial C:N ratio of56.58)after adding urea (1.07 g L -1 ) and peptone (3.25 g L -1 ) in total concentration of 1.00 g L -1 (as in Table II). The optimum C:N ratio for B. bassiana BNBCRC was about 3 times higher than those for B. bassiana (C: N ratio of 10: 1, using sucrose and casamino acid) [2],and Metarhiziumanisopliae SQZ-1-21 (C: N ratio of 10:1 and 20:1) [18]. However, it was 18.5 times higher than that for Metarhizium flavoviride Mf189 based on sucrose and brewer's yeast (with a C: N ratio of 1.6) [19].…”

“…Todavia, a resposta pode ser variável, não havendo uma relação que seja regra para todos os entomopatógenos, como reportado por Gao et al (2007) de avaliar a produção de biomassa em cinco meios líquidos, além de um meio com diferentes concentrações de melaço e extrato de levedura. Em todos os meios usados foram quantificados a biomassa, porém o meio que continha melaço e extrato de levedura foi o que produziu maior biomassa com 13,18 g.L -1 , superando em três vezes a produção dos demais tratamentos, isso porque, os fungos são favorecidos por meios de cultivos capazes de fornecer carbono e nitrogênio, como é o caso do meio apresentado.…”
