in a 42-d experiment, 576 one-day-old vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. the inclusion of bio choline and lecithin extract in the diet signifi...

Lignocellulosic biomass is an abundant and renewable resource for biofuels and bio-based chemicals. Vanillin is one of the major phenolic inhibitors in biomass production using lignocellulose. To assess the response of Corynebacterium glutamicum to vanillin stress, we performed a global transcriptional response analysis. The transcriptional data showed that the vanillin stress not only affected...

Dioxin-like compounds including polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) are polyhalogenated aromatic hydrocarbons (PHAHs) that bio-concentrate, bio-accumulate and bio-magnify because of their hydrophobicity, and persistence in the environment. These compounds are formed as a result of incomplete combustion during cert...

Aromatase is the enzyme that converts androgen to estrogen. Our laboratory has proposed and demonstrated that aromatase is an important target of some environmental chemicals. We have found that some of these compounds inhibit aromatase activity, resulting in a decrease in the level of estrogen or an increase in the level of androgen in cells. Environmental chemicals can also modify the express...

Depleting oil reserves and growing environmental concerns have necessitated the development of sustainable processes to fuels and chemicals. Here we have developed a general metabolic platform in E. coli to biosynthesize carboxylic acids. By engineering selectivity of 2-ketoacid decarboxylases and screening for promiscuous aldehyde dehydrogenases, synthetic pathways were constructed to produce ...

from the time of antiquity two lines of thinking were always predominant, the materialistic and the spiritualistic viewpoint. the materialistic point of view states the human beings and other living creatures come to life according to a specific pattern and constellation of chemicals and molecules. on the other hand, the nonmaterialistic view point emphasizes that the life factor is something m...

Every year lots of black tea (Camellia sinensis (L.) Kuntze) residue will produce in the factories. These residue are unusable whereas the bio active compounds can be extracted and used in the drag and food industries. Due to mentioned problems, this project was conducted years 2011 - 2012 with the aim to make a study on consecutive isolation of all bio active compounds from tea residu...
