Under stationary and anaerobic conditions, greater cell yields of Lactobacillus brevis were obtained from autoclaved than from filter-sterilized glucose media. Fructose, tentatively identified as a product generated by the heating process, served as an excellent catalyst for inducing growth. The addition of micromolar quantities of pentoses or potential pentose precursors to the filter-steriliz...

anaerobic treatment methods are more suitable for the treatment of concentrated wastewater streams, offer lower operating costs, the production of usable biogas product. the aim of this study was to investigate the performance of an anaerobic fluidized bed reactor (afbr)-aerobic moving bed bio reactor (mbbr) in series arrangement to treat currant wastewater.the bed materials of afbr were cylind...

Introduction: The aim of this study was to compare the protective effects of two types of aerobic and intermittent training on breast cancer as a result of TGFβ protein, Smad-3, and MMP2 gene in female mice. Methods: In the experimental study, a total of 24 female BALB/c mice after Tumorigenesis by MC4-L2 cell line in the three groups; Control, Aerobic, and Intermittent training groups,...

Antimicrobial peptides (AMPs) can cause lysis of target bacteria by directly inserting themselves into the lipid bilayer. This killing mechanism confounds the identification of the intracellular targets of AMPs. To circumvent this, we used a shuttle vector containing the inducible expression of a human cathelicidin-related AMP, LL-37, to examine its effect on Escherichia coli TOP10 under aerobi...

Aerobic acetylene-degrading bacteria were isolated from soil samples. Two isolates were assigned to the species Rhodococcus opacus, two others to Rhodococcus ruber and Gordona sp. They were compared with known strains of aerobic acetylene-, cyanide-, or nitrile-utilizing bacteria. The acetylene hydratases of R opacus could be measured in cell-free extracts only in the presence of a strong reduc...

Objective: Laboratory studies on diabetic rats have shown that diabetic rats have a lower beta cell mass than healthy rats. On the other hand, over the years, with tremendous advances in genetic science, many studies have been done on the expression of genes and its effective factors, such as physical activity. One of these genes is AKT / PKB. Due to the association between the expression of th...

This paper describes experimental research to directly quantify the ordinary heterotrophic organism (OHO) cell yield coefficient under anoxic and aerobic conditions with real wastewater as substrate. Until recently these two values were assumed equal in activated sludge models, despite theoretical predictions that the anoxic yield should be reduced relative to its aerobic value. In this study, ...

Aerobic exercise is a promising form of prevention for cognitive decline; however, little is known about the molecular mechanisms by which exercise and fitness impacts the human brain. Several studies have postulated that increased regional brain volume and function are associated with aerobic fitness because of increased vascularization rather than increased neural tissue per se. We tested thi...
