Isolation and characterization of a newly isolated Pseudomonas mutant for protease production

Abstract

ABSTRACT

Production and some properties of crude alkaline proteases of indigenous Central Amazonian rhizobia strains

“…4). The temperature range for optimum catalytic activity of numerous proteases was between 30 and 47 o C (Schokker and van Boekel, 1997;Singh et al, 2001;Dutta and Banerjee, 2006;Genckal and Tari, 2006). At temperatures from 25 to 55 o C, significant increases in enzyme activity of strain R-993 were observed (Fig.…”

Kinetic study of free and immobilized protease from Aspergillus sp

“…For the commercial exploitation of enzyme it is desirable to choose an enzyme, which will have the fastest reaction rate per unit amount of enzyme. Reaction rate indicates the maximum effect for minimum amount of added catalyst [22].…”

Hyper-production of Alkaline Protease by Mutagenic Treatment of Bacillus subtilis M-9 using Agroindustrial Wastes in Submerged Fermentation

“…Mutation and screening of industrially useful microorganisms are very important for the successful development of various strains which are required in the fermentation industry [29]. Therefore, the parent strain B. subtilis M-9 was treated with different mutagens like UV irradiation, NTG (N-methyl-N-nitro-N-nitrosoguinidine) and EB (ethidium Bromide), to improve its productivity.…”

“…This increase in optimum temperature might be due to formation of chaperones or heat shock proteins with some hydrophobic amino acids, in response to induced genetic mutation that supports high product formation at higher growth permissible temperature. Dutta and Bannerjee [29] [32] found 60 º C optimum temperatures for alkaline protease production by mutant strain of Bacillus pumilus.…”
