Increased temperatures from global climate change are projected to cause substantial losses in crop productivity by the end of the twenty-first century. High temperature is predominant among the cardinal ecological factors that determine crop growth and productivity (Al-Khatib and Paulsen, 1999). In cotton, temperature is a primary controller of the rate of plant growth, developmental events, a...

Polyphenol oxidases are found both in prokaryotic and eukaryotic microorganisms, in mammals, invertebrates and plants. Most plants have multiple forms of PPO. The more recent articles regarding the polyphenol oxidases from different plants are reviewed. The main characteristics considered were the sources, structure and properties of polyphenol oxidase (PPO) as well as the inhibitors of this en...

This paper investigates the thermodynamic framework of a three-bed advanced adsorption chiller, where the mass recovery scheme has been utilized such that the performances of this chiller could be improved and a CFC-free-based sorption chiller driven by the low-grade waste heat or any renewable energy source can be developed for the next generation of refrigeration. Silica gel-water is chosen a...

Objective: The objective of the study was to develop and evaluate the reverse phase ultra-performance liquid chromatography (RP-UPLC) method for the quantitative determination of potential impurities of rivaroxaban active pharmaceutical ingredient. Method: The method uses a water acquity BEH C8 column (100mm x 2.1 mm, 1.7μm) with mobile phase A consisted, 0.05M diammonium hydrogen phosphate, pH...

Lysine as an essential amino acid supplemented to fulfil the dietary requirement of Poultry feed. In Pakistan all this demand is accomplished by importing lysine for feed sector. Wild Brevibacterium flavum was used to induce mutation by random mutagenesis for hyper production of lysine through fermentation. The highest lysine producing strain (BFENU2) was screened with 21.64 g/L production by m...

We developed predictive growth models for Staphylococcus aureus and Bacillus cereus on various food matrices consisting primarily of ready-to-eat (RTE) foods. A cocktail of three S. aureus strains, producing enterotoxins A, C, and D, or a B. cereus strain, were inoculated on sliced bread, cooked rice, boiled Chinese noodles, boiled bean sprouts, tofu, baked fish, smoked chicken, and baked hambu...

Bacillus sp. MG-33 was isolated from the desert of Rajasthan (India). The organism produced 500 and 200 Ug of thermostable mannanase (after 96h) in solid state fermentation (SSF) of wheat bran and wheat straw rich-soda pulp at the moisture ratio of 1:1.5 and 1:3 at 30oC, respectively. Two-step partially purified mannanase was optimally active at 65oC and was 100% thermostable at 55 to 60oC for ...

The area of nanotechnology encompasses the synthesis of nanoscale materials, the understanding and the utilization of their physicochemical and optoelectronic properties, and the organization of nanoscale structures into predefined superstructures. The development of biologically inspired experimental processes for the synthesis of nanoparticles is evolving into an important branch of nanotechn...

The immunoglobulin (Ig) constant CH2 domain is critical for antibody effector functions. Isolated CH2 domains are promising scaffolds for construction of libraries containing diverse binders that could also confer some effector functions. We have previously shown (Gong et al., JBC 2009) that an isolated human CH2 domain is relatively unstable to thermally induced unfolding but its stability can...

Chitinase production by newly isolated Serratia marcescens B4A was optimized following Taguchi’s array methods. Twenty-three bacterial isolates were screened from shrimp culture ponds in the South of Iran. A chitinase-producing bacterium was isolated based on it’s ability to utilize chitin as the sole carbon source. The isolate designated as B4A, was identified as Serratia marcescens based on i...
