ABSTRACT
The purpose of this investigation was to study the effect of Bacillus subtilis CM5 in solid state fermentation using cassava bagasse for production of Exo-polygalacturonase (exo-PG). Response surface methodology was used to evaluate the effect of four main variables, i.e. incubation period, initial medium pH, moisture holding capacity (MHC) and incubation temperature on enzyme production. A full factorial Central Composite Design was applied to study these main factors that affected exo-PG production. The experimental results showed that the optimum incubation period, pH, MHC and temperature were 6 days, 7.0, 70 percent and 50ºC, respectively for optimum exo-PG production.
RESUMO
O objetivo desta investigação foi estudar a produção de exo-poligalacturonase (exo-PG) por Bacillus subtilis CM5 por fermentação em estado sólido empregando bagaço de mandioca. Empregou-se a metodologia de superfície de resposta para avaliar o efeito de quatro variáveis na produção da enzima período de incubação, pH inicial do meio, MHC e temperatura de incubação. Os resultados experimentais mostraram que os ótimos de temperatura, período de incubação, MHC e temperatura para produção de exo-PG foram seis dias, 7,0, 70 por cento e 50ºC, respectivamente.
