BACKGROUND Conventional corn dry-grind ethanol production process requires exogenous alpha and glucoamylases enzymes to breakdown starch into glucose, which is fermented to ethanol by yeast. This study evaluates the potential use of new genetically engineered corn and yeast, which can eliminate or minimize the use of these external enzymes, improve the economics and process efficiencies, and si...

The oxidation of the bladder carcinogen 2-naphthylamine (2-NA) by prostaglandin H synthase (PHS) in vitro was examined. Oxygen uptake studies of 2-NA oxidation in the presence of glutathione, as well as extensive product analysis data, are consistent with a one-electron mechanism of 2-NA oxidation by PHS. The formation of 2-nitrosonaphthalene is not observed under any condition. Metabolism stud...

Besides the high starch content, sweet potato contains endogenous amylases where the two Predominants are - and β-amylases. Sweet potato is thought to be a promising source of β -amylase since β -amylase is one of the major protein in the tubers. This investigation has focused on the properties of β amylase from white-flesh sweet potato that has been grown in Iran as a potential source for indu...

A total of 50 root colonising bacterial endophytes were identified from a medicinal plant in this investigation (Barleria lupulina), and characterized based on morphologically selected isolates, BLR41 Gram-negative motile, rod-shaped BLR45 was Gram-positive, rod-shaped, light yellow color. The isolate motile the positive for indole. strains citrate, amylase, protease, lipase. Among all exhibite...

In the parotid, as well as in other exocrine glands, secretory protein synthesis declines with age. However, whether this decline in the steady-state rate of protein synthesis reflects the reduced digestive activity of the animal or actual cellular alterations that affect synthesis is unknown. Here the ability to synthesize amylase and its mRNA during the period of enhanced protein synthesis fo...

This is an in vitro study to evaluate five different commercially available citrus fruits: viz., Sweet orange (Citrus sinences Osbeck), Grape [Citrus maxima (J. Buruan) Merrile], Lemon [Citrus limon (Burn F.) and Lime (Citrus aurantifolia Swingle. Evaluation of their pHs and neutralizable acidity were made. A 50 mL of each fruit was prepared by juice press. Initial pH was measured in triplicate...
