“…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.…”

The use of agriculture substrates in industrial biotechnological processes has been increasing because of its low cost. Cashew apples are considered an agriculture low cost product in the Brazilian Northeast because the cashew cultivation is done mainly to produce cashew nuts. About 90% of the cashew apples production is lost in the field after removing the nut. In this work, the use of clarified cashew apple juice as substrate for microbial cultivation was investigated. The results showed that cashew apple juice is a good source of reducing sugars and can be used to grow Leuconostoc mesenteroides to produce high added value products such as dextran, lactic acid, mannitol and oligosaccharides.

Cashew apples are considered agriculture excess in the Brazilian Northeast because cashew trees are cultivated primarily with the aim of cashew nut production. In this work, the use of cashew apple juice as a substrate for Leuconostoc mesenteroides cultivation was investigated. The effect of yeast extract and phosphate addition was evaluated using factorial planning tools. Both phosphate and yeast extract addition were significant factors for biomass growth, but had no significant effect on maximum enzyme activity. The enzyme activities found in cashew apple juice assays were at least 3.5 times higher than the activity found in the synthetic medium. Assays with pH control (pH = 6.5) were also carried out. The pH-controlled fermentation enhanced biomass growth, but decreased the enzyme activity. Crude enzyme free of cells produced using cashew apple juice was stable for 16 h at 30 degrees C at a pH of 5.0.
