Optimization of the production of roasted-nutty aroma by a newly isolated fungus Tolypocladium inflatum SRH81 and impact of encapsulation on its quality.

Background: Pyrazines are used in food industry to impart the foods nutty-roasted flavor. However, their extraction from natural sources is difficult and expensive. At the same time, there is awareness against the chemical food additives.

Human apoptosis antibody array-membranes studying the apoptotic effect of marine bacterial exopolysaccharides in HepG2 cells.

Background: Hepatocellular carcinoma (HCC) is considered as the third leading cause of cancer-related deaths, in spite of great advances in its treatment. The carbohydrate polymers, exopolysaccharides (EPSs), showed anticancer activity in diverse cancers.

Objective: The purpose of this study is to investigate a panel of 43 apoptotic proteins to assess the possible apoptotic induction effect of bacterial EPSs showing promising cytotoxic effects in HepG2 cells in our previous study, in an attempt to introduce exopolysaccharides as new source for cancer treatment.

Diverse bioactive metabolites from Penicillium sp. MMA derived from the red sea: structure identification and biological activity studies.

A soft coral-derived fungus Penicillium sp. among other isolates e high antibacterial, anti-yeast and cytotoxic activities. The fungus, Penicillium sp.

Nutty-like flavor production by 1220T from enzymatic soybean hydrolysate. Effect of encapsulation and storage on the nutty flavoring quality.

The main objective of this study was to evaluate the ability of to produce a safe nutty like flavor from enzymatic soybean meal hydrolysate (E-SH) and to investigate the effect of encapsulation and storage on the quality of the produced nutty flavoring. was incubated with E-SH, supplemented and un-supplemented with a mixture of threonine and lysine. The generated volatiles of each culture were subjected to odor sensory analysis.

Production of hydroxy marilone C as a bioactive compound from.

Hydroxy marilone C is a bioactive metabolite produced from the culture broth of isolated from Egyptian soil. Hydroxy marilone C was purified and fractionated by a silica gel column with a gradient mobile phase dichloromethane (DCM):methanol then Sephadex LH-20 column using methanol as a mobile phase. It was subjected to many procedures such as infrared (IR), nuclear magnetic resonance (NMR), Mass spectroscopy (MS) and UV spectroscopy for elucidation of its structure.

Efficacy of polysaccharide from Alcaligenes xylosoxidans MSA3 administration as protection against γ-radiation in female rats.

Damage to normal tissues is a consequence of both therapeutic and accidental exposures to ionizing radiation. A water-soluble heteropolysaccharide called AXEPS, composed of glucose, galactose, rhamnose and glucouronic acid in a molar ratio of nearly 1.0:1.

Effect of pH on growth and biochemical responses of Dunaliella bardawil and Chlorella ellipsoidea.

The goal of the present investigation was to study the effect of pH on growth and biochemical responses of Dunaliella bardawil and Chlorella ellipsoidea when exposed to different pH values. The two tested microalgae could grow in a wide range of pH (4-9 for D. bardawil and 4-10 for C.
