“…Carbon and nitrogen sources are important variables that affect the growth and products of microbes [30]. Many authors had reported variability of carbon and nitrogen sources with different microorganisms [31][32][33]. Shafee et al [30] had reported that maximum protease was produced in medium containing glucose and beef extract, which was similar to our findings with S. albolongus.…”

“…To high action of the fungus, is it possible the aqueous extract may have enriched the culture medium providing a greater quantity of compounds to be assimilated by fungus and the fungus' rapid metabolism increased the production of extracellular proteases, and therefore, unlike that observed with peracetic acid, the infectious process is accelerated and increased the percentage of mortality (Rombach, 1989;Leite et al, 2003;Ito et al, 2007).…”

“…Foram realizados cultivos submersos da cepa de B. bassiana CG432 a 28ºC, 150rpm através da inoculação de 1% de uma suspensão contendo 10 8 conídios/mL recém-ativados em broca-do-café utilizando meio de cultura líquido com a mesma composição do meio sólido, porém sem adição de ágar e preparado conforme descrito por Ito et al (2007), porém aumentando a relação espaço aéreo/ meio de cultivo para 1/5. Todos os cultivos foram realizados em triplicata.…”

“…B. bassiana cepa CG432 isolada de insetos mortos Hemiptera: Membracidae na região nordeste do Brasil, demonstrou elevado crescimento sobre adultos de broca do café Hypothenemus hampei (Ferrari) HIROSE, 2005), e rápida produção de proteases extracelulares em apenas 2 dias de cultivo inoculado com suspensão de conídios previamente ativados em seu hospedeiro (ITO et al, 2007), sendo este tempo de produção de proteases, muito inferior aos publicados por cultivos de B. Bassiana realizados em meio enriquecidos com substratos protéicos como gelatina e caseína (URTZ; RICE, 2000) ou com cutícula moída de gafanhoto (St LEGER et al, 1986a).…”
