The production of pullulan from molasses and synthetic medium by Aureobasidium pullulans P56 in batch culture was investigated. Among the pretreatments of molasses used to increase polysaccharide production, sulfuric acid + activated carbon treatment gave better results with regard to polysaccharide concentration, polysaccharide yield and sugar utilization. A maximum polysaccharide concentratio...

Myoblast cells, C2C12, which is an established cell line from satellite cells of skeletal muscle of C3H mouse, start to fuse and form multinucleated cells (myotubes) and begin to express creatine phosphokinase and myosin, when culture medium is changed from the growth medium to the differentiation medium. Among the 12 lectins that we tested, wheat germ agglutinin apparently suppressed the myotu...

production of lysine by corynebacterium glutamicum (ptcc 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. for this purpose, ammonium sulphate was selected as a constant nitrogen source. the effect of different nitrogen sources was also investigated with glucose as a constant carbon source. the production of l-lysine was exam...

BACKGROUND Biodegradable polyesters are candidates for the development of environmental friendly plastics. Poly-β-hydroxybutyrate (PHB) is a type of polyester from the hydroxyalkanoates family, synthesized by bacteria as an intracellular material and accumulated as granules in the cytoplasm. OBJECTIVES The aim of this study was to isolate Poly β-hydroxybutyrate over producing bacteria and opt...

Synthetic pesticides have a number of ill effects on soil, water, human health, wildlife and ecological balance. These ill effects have led to the use of microbial insecticides against insect pests of order Lepidoptera, Coleoptera, Diptera and Hemiptera. Bacillus thuringiensis is a gram-positive endospore forming bacterium that produces a parasporal crystal protein inclusion during sporulation ...

Sugarcane molasses is rich in nutriments and vitamins. It may be used as the carbon source for the production of polyunsaturated fatty acids (PUFA) by Mucor recurvus sp. Using sugarcane molasses, the effects of fermentation parameters and media components on polyunsaturated fatty acid production through both linear and orthogonal array experiments were investigated. The best fermentation condit...

The objective of this study was to investigate the effects of adding different levels of molasses (1-5%) on the silage quality, in vitro methane production and in vitro organic matter digestibility (IVOMD) of pistachio (Pistachio vera) by-product and wheat straw mixture silages. For this purpose, silages were prepared with pistachio by-product (85%) and wheat straw (15%) without molasses (contr...
