| Alpha amylase (α-1, 4-glucan-glucanhydrolase, EC 3.2.1.1), an extracellular enzyme, degrades α, 1-4 glucosidic linkages of starch and related substrates in an endo-fashion producing oligosaccharides including maltose, glucose and alpha limit dextrin (7). The present study deals with the production and comparative study of production of α-amylase from two strains of Bacillus licheniformis, MTCC 2617 and 2618, by using four different substrates, starch, rice, wheat and ragi powder as carbon source by submerged fermentation. The effect of varying pH and incubation temperature, activator, inhibitor, and substrate concentration was investigated on the activity of α-amylase produced by MTCC strain 2618. The results shows that the production of the α-amylase by... |

| ABSTRACT The present study was concerned with the searching of novel bacterial cultures from different samples for the lab scale production of pectinase. Keeping in view the increasing demand of pectinase specially in Faisalabad, an industrial city of Pakistan, isolation of new hyper producer bacterial strains locally is an easy and cheap way of getting the desirable products at low cost. Therefore, isolation of new strains for industrial enzyme production has been and will be remained a part of research every time. This method alone can also provide raw material for further research such as enzyme engineering or molecular directed evolution. For the identification of hyper producer strain colony PCR was done for 16S rRNA analysis. Reason to use the 16S... |
