Effect of carbohydrates and amino acids on fermentative production of alpha amylase: Solid state fermentation utilizing agricultural wastes

Research Paper (undergraduate) from the year 2012 in the subject Chemistry - Bio-chemistry, grade: "-", , language: English, abstract: Extracellular alpha amylase was produced from Aspergillus oryzae under solid state fermentation. House hold agro-wastes were used as medium which were considered as one of the major pollutants due to unfavorable gas production via natural fermentation beside creating disposal problem. Investigations were carried out to evaluate the effect of various carbohydrate sources e.g. glucose, maltose, lactose, sucrose and soluble starch with different concentrations on the production of fungal alpha amylase utilizing agricultural wastes as the fermentation medium. Studies were also carried out to evaluate the effect of various heat stable amino acids e.g. glycine, histidine, proline, leucine and isoleucine with different concentrations on the production of fungal alpha amylase utilizing agricultural wastes as the fermentation medium. The results indicated that maximum activity of alpha amylase (6639.85 U/gds) was obtained at 0.5% concentration of sucrose solution with a r2 of 0.9692 when compared to control (3319.95 U/gds) and other carbohydrates used. Maximum activity of alpha amylase (10407.80 U/gds) was also obtained at 0.75% concentration of proline solution with an r2 of 0.6816 when compared to control (3035.60 U/gds) and other amino acids used in our present study.
