“…The pH of the fermentation medium is the most critical parameter for amylase production process therefore maintenance of the medium pH is paramount for successful fermentation of amylase. Fungal strains tend to thrive best in acidic medium ranging from 3 to 6 (Fawole and Odunfa, 2003), hence the pH range of 2 to 6 is frequently utilized for submerged and solid state fermentation (Adham, 2002;Lesuiak et al, 2002). Sivaramakrishnan et al, (2006) also opined that slightly acidic pH is needed for fungi growth.…”

“…Aspergillus e Rhizopus são freqüentemente usados pela alta atividade pectinolítica exibida nos extratos produzidos. 9 A produção de pectinases por microrganismos é influenciada pelas condições de cultivo, em particular do meio de cultura, tipo e concentração da fonte de carbono, pH e temperatura do cultivo, além de outros fatores. 10 O nível de umidade do substrato é um dos fatores que mais influenciam o processo e varia de acordo com a natureza do substrato, tipo de produto final e necessidade do microrganismo.…”

“…Most filamentous fungi are mesophilic requiring optimal temperatures between 25 and 35°C (Reid, 1998;Suresh et al, 1999). A temperature of 40°C was identified as optimum for metabolite production and sugar utilization by A. niger ATCC 10577 and A. niger V. Tiegham (Roukas, 2000;Fawole and Odunfa, 2003).…”
