چکیده

New cytokine production inhibitors, CJ-14,877 (I) and CJ-14,897 (II), were isolated from the fermentation broth of a basidiomycete, Marasmiellus sp. CL21624. Their structures were determined to be methyl-(7S,8S)-5-(7,8-dihydroxypropyl)pyridine-2-carboxylate and methyl-(7S,8S)-5-(8-acetoxy-7-hydroxypropyl)pyridine-2-carboxylate [corrected], respectively, by spectroscopic analyses. These compounds showed inhibitory activities for lipopolysaccharide-induced production of interleukin-1beta and tumor necrosis factor-alpha in human whole blood with IC50 values of the range from 0.059 to 2.6 microM.

Optimization of Culture Conditions and Medium Components for Carboxymethyl Cellulase (CMCase) Production by a Novel Basidiomycete Strain Peniophora sp. NDVN01

Background: Cellulytic enzymes including carboxymethyl cellulases play the key role in hydrolysis of cellulose, a huge organic carbon reservoir on earth, into monomeric sugars and their eventual conversion into valuable chemicals and energy sources. Objectives: In this study, we described the identification of a basidiomycete isolate NDVN01 and optimization of culture conditions and medium com...

A novel low molecular weight extracellular protease from a moderately halophilic bacterium Salinivibrio sp. strain MS-7: production and biochemical properties

Kinetics of bacterial growth and protease production were monitored on a novel isolated moderately halophilic bacterium, Salinivibrio sp. strain MS-7, and maximum growth and protease activity was achieved after 48 hours at 30°C and 180 rpm. To determine the effect of various carbon sources on protease production, glucose, lactose, sucrose and maltose were investigated and  maximum production of...

Study on Activity and Stability of Proteases from Bacillus Sp. Produced by Submerged Fermentation

Objective: Investigations were carried out to isolate bacteria from saline-alkali soils and determined optimized alkaline protease activity and stability produced by a wild strain of bacillus sp. in submerged fermentation (SMF). Methods: Optimum temperature for enzyme activity in the crude extract was 40 ◦C at a pH between 8.0 and 9.0. The studies on pH stability showed that the enzyme...

Production of bacteriocin by a novel Bacillus sp. strain RF 140, an intestinal bacterium of Caspian Frisian Roach (Rutilus frisii kutum)

Bacteriocins are proteinaceous antibacterial compounds that exhibit bactericidal activity against species closely related to the producer strain. The aim of this research was to investigate the production of bacteriocin by Bacillus spp. isolated from intestinal bacterial flora of the Caspian Frisian Roach (Rutilus frisii kutum). A bacteriocin produced by the bacterium Bacillus cereus strain RF ...
