background: proteolytic enzymes have an important role in variety of physiological and pathological functions. they have been used in therapeutic and pharmaceutical applications. characterizations of extracellular proteases from various strains of s. marcescens indicate that most strains produce a very similar major metalloprotease. this metalloprotease (serrapeptidase, serrapeptase) is an impo...
Background: a-Amylases (EC 3.2.1.1) are covering approximately 25% of total enzyme market and are frequently used in food, pharmaceutical and detergent industries. Objectives: The first ever detailed characterization of amylase from any halophilic Engyodontium album is presented. Materials and Methods: An extracellular α-amylase was studied from halophilic E. album TISTR 3645. The enzyme was e...

Benzyl Alcohol Dehydrogenase (BADH) is an important enzyme for hydrocarbon degradation, which can oxidize benzyl alcohols to aldehydes, while being capable of catalyzing a reversible reaction by reducing benzaldehyde. BADH is a member of medium chain alcohol dehydrogenases, in which zinc and NAD are essential for enzyme activity. This paper describes the expression, purification, and characteri...

It is now well established that even though Pd supported on acidic zeolites is highly selective for CH4-SCR, zeolitic structures are susceptible to dealumination under hydrothermal environments. In this contribution, we have investigated the ability of non-zeolitic acidic materials to promote the SCR selectivity and stability in the presence of H2O and SO2. The results of catalytic activity mea...
background: today a large number of bacterial amylases are available commercially in industry. the goal of the present study was purification and biochemical characterization of an extracellular thermostable alkaline α-amylase from the novel moderately halophilic, bacillus persicus from the aran-bidgol, iran. methods : purification of enzyme, was carried out by acetone precipitation, ultrafil...
this research has focused on isolation and characterization of a strain of bacillus sp. from alkaline soil, which was able to produce extracellular alkaline protease at phs ranging from 8 to 11 and temperatures of 20 to 50ºc. also the impact of different carbon andnitrogen sources were investigated. the yield and fold of enzyme purification was 24% and 50 times, respectively. molecular weight o...
Background: Typically, non-cellulytic glucanase, including fungi and yeast cell wall hydrolyzing enzymes, are released by some symbiotic fungi and plants during the mycoparasitic fungi attack on plants. These enzymes are known as the defense mechanisms of plants. This study intends to investigate the biochemical properties of β-1,6-glucanase (bg16M) from native thermophilic bacteria, Cohne...
Bacillus licheniformis RM44 was isolated from hot spring near Karachi and screened forthe production of extracellular amylase Amy RM44. Amy RM44 was purified to homogeneityon a single step by affinity chromatography using insoluble corn starch. The molecular weightof Amy RM44 was estimated to be 66 kDa by SDS–PAGE and zymographic analysis. Nine foldpurification was achieved with the specific ac...
