background and objectives: auto-induction is usually employed to achieve high cell density and overproduction of proteins with a simple and low-cost operation. the efficiency of heterologous protein expression in escherichia coli is determined by different parameters. interactions between these parameters usually complicate the identification of those that contribute more to the improvement of ...
The spread of multidrug resistance among bacterial pathogens poses a serious threat to public health worldwide. Recent approaches towards combating antimicrobial resistance include repurposing old compounds with known safety and development pathways as new antibacterial classes with novel mechanisms of action. Here we show that an analog of the anticoccidial drug robenidine (4,6-bis(2-((E)-4-me...
Present study was conducted to evaluate the effect of aqueous methanolic extract from Saccharum officinarum on the sporulation and morphology of oocysts of four Eimeria species (Eimeria tenella, E. necatrix, E. mitis, E. brunetti) of poultry. Sporulation inhibition bioassay was used to evaluate the activity of Saccharum officinarum extract (SOE) on the sporulation of coccidian oocysts. In this ...
AIM This study aims to produce and assay cellulolytic enzyme activity (endo-(1,4)-β-D-glucanase, exo-(1,4)-β-D-glucanase, and β-glucosidase, at optimum temperature and optimum pH) of Enterobacter cloacae WPL 214 isolated from bovine rumen fluid waste of Surabaya Abbatoir, Indonesia. MATERIALS AND METHODS To produce enzyme from a single colony of E. cloacae WPL 214, 98 × 10(10) CFU/ml of isola...
the activity of phospholipase c in crude enzymatic preparation of melia azadiracht seeds (neem seeds) was studied by the use of lecithin as a substrate in aqueous medium. the enzyme activity was found optimum at ph 2.5 and temperature 35?c. the phospholipase c was found heat labile, being inactivated 88% within 10 minutes at 90°c
The field experiments were conducted on sandy loam soil at New Delhi, during 2007 and 2008 to investigate the effect of conservation tillage, irrigation regimes (sub-optimal, optimal and supra-optimal water regimes), and integrated nutrient management (INM) practices on soil biological parameters in wheat cultivation. The conservation tillage soils has shown significant (p<0.05) increase in soi...
microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. in addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. bacillus sp. dm12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
A bacterium, isolated from rabbit’s waste and identified as Cellulomonas sp., had cellulase and thermostable α-amylase activity when grown on wheat bran. Maximum activity of thermostable α-amylase was obtained by adding 3% soluble starch. However, soybean oil (1 ml l) could increase the production of α-amylase and cellulase in wheat bran. The α-amylase was characterized by making a demonstratio...
Pectin methylesterase (PME) from green bell peppers (Capsicum annuum) was extracted and purified by affinity chromatography on a CNBr-Sepharose-PMEI column. A single protein peak with pectin methylesterase activity was observed. For the pepper PME, a biochemical characterization in terms of molar mass (MM), isoelectric points (pI), and kinetic parameters for activity and thermostability was per...
