Hydrolysis of starch by amylase from Bacillus sp. KCA102: a statistical approach

Optimization of amylase production from Bacillus sp. using statistics<br>based experimental design

“…In this study, for amylase production optimum at pH 11.35 was found; above and below this pH there was probably due poor microbial growth in acidic and alkaline medium (Kar and Ray, 2008). Also, similarly various research on optimization of physical parameters for amylase studies were reported in literature (Agrawal et al, 2005;Kar and ray, 2008;Tamilarasan et al, 2010). The application of properly designed models with multi-factor analysis allow process and biochemical engineers to design scale up strategies for increasing enzyme production.…”

Corn porous starch: Preparation, characterization and adsorption property

“…With the pH value increasing, both hydrolysis ratio and adsorption ratio increase at first, and then decrease. Enzyme is a kind of biochemical reagent and its activity has a great relationship with the pH value [21]. The rate of a biochemical reaction and the enzyme activity are greatly influenced by the structure of the enzyme.…”

“…From the figure, it can be seen that, with reaction temperature increasing, the hydrolysis ratio shows an upward tendency, while the adsorption ratio first increases, and then decreases. Temperature is another important restrictive factor to the enzymatic activity [21,22]. ␣-Amylase and glucoamylase have less activity when the environmental temperature is low.…”

Production of α-amylase from Streptomyces sp. SLBA-08 strain using agro-industrial by-products

“…(2003) reported several amylase-producing bacterial isolated from soil samples and the promising strain was identified as Bacillus sp. Agrawal et al (2005) reported 33 bacterial colonies which showed a zone of clearance surround the microbial growth in starch medium, isolated from four different locations in IIT-Madras campus, Chennai, Índia.…”
