“…The increase of glucoamylase production with increasing concentration of rice bran indicates that the enzyme may be inducible. Windish & Mhatre (1965) have reported the stimulatory effect of various metal ions such as Mn 2+ Zn 2+ Fe 3 § and Na + on amylase production. In contrast, metal ions could not stimulate the enzyme production in Aspergillus terreus.…”

“…Of them, amylase and protease are very important enzymes in industrial level (Burhan et al, 2003;Dhanasekaran et al, 2006;Saxena et al, 2007;Alamri, 2010;Vaseekaran et al, 2010;Divakaran et al, 2011;Abdel-Fattah et al, 2013;Deb et al, 2013). Amylase plays a vital role in the hydrolysis of starch to dextrin and other small polymers constituted of glucose units (Windish and Mhatre, 1965), and the enzyme derived from various sources including plants, animals and also microorganisms (Pandey et al, 2000).…”

Total of 56 bacterial isolates were isolated from five palm tree cultivated soil samples and screened their amylase production. In the preliminary screening, twenty four isolates exhibited amylase producing ability. Among these 24 isolates, an isolate KSU-6 showed maximum amylase enzyme production (37.52 U mL -1 ), and the isolate was identified as Bacillus licheniformis KSU-6. The maximum amylase production was optimized, and the conditions were pH 10.0, temperature 50 o C, incubation period 44 h, inoculum concentration 2% (v/v), starch 0.2% (w/v) as carbon source, peptone 0.5% (w/v) along with malt extract 0.3% (w/v) as nitrogen sources for B. licheniformis KSU-6. The partially purified amylase stabled upto pH 12, temperature 80 o C, 1-2 M salt concentration and 10 mM of different detergents. In this study conclude that the soil bacterium Bacillus licheniformis KSU-6 produced thermostable and alkaline amylase, which could be useful for industrial liquefaction and detergent industries.

“…Branched oligosaccharide resulting from the hydrolysis of starch is effectively used as anticarcinogenic oligoisaccharides (Nakakuki et al, 2002). Moreover the hydrolysis of starch give rise to dextrin that has extensive biotechnological application in bread and baking industry (Windish and Mhatre, et al, 1965). Thus it is apparent that starch saccharification has wide application in baking, brewing, detergent, textile, paper and distilling industry (Souza and Magalhaes, et al, 2010).…”

Amylase is one of the leading enzymes used in industry from decades. The preliminary function of this enzyme is the hydrolysis of the starch molecule into glucose units and oligosaccharides. Amylases have spectacular application in broad spectrum of industries such as food, detergent, pharmaceutical and fermentation industries. Among different type of amylases α-amylase is in utmost demand because of its striking features. This particular enzyme is a good substitute over the chemicals catalyst used in industries. α-amylases can be acquired from different sources such as microorganism, animals and plants. Microorganisms are the major source of production of amylase because of the ease of availability, manipulation and operation. The starch converting enzymes is basically generated using submerged fermentation. Some of the prominent characteristics of amylase are its mode of action, substrate specificity and operating condition (temperature and pH). Amylases from different bacterial sources contribute differently to the particular trait of the enzyme. Bacillus amylases have been studied and applied so far because of their robustness in nature and easy accessible pure form of it. Thus this makes it more specific and fit for distinct application in the industry. The purpose of this manuscript was the comparative analysis of the physical and chemical features of α amylases from Bacillus species. It also focuses on the unique characteristics of this enzyme and their industrial applications.
