Streptomyces sp. PG-08-3 was isolated from the desert of Rajasthan (India). The organism produced mannanase (15 Umg protein) in the presence of 0.5% guar gum as a sole carbon source in minimal media by submerged fermentation (SmF). Enzyme production was enhanced by 7.3-fold when 0.5% soyabean meal and 0.25% of leucine were added to the minimal media. Increasing the guar gum concentration in the...

The present study was carried out to evaluate the effect of Guar meal, an unconventional feed on growth performance, behavioural traits, faecal consistency in kids (3 months old) with an average body weight of 9.46 ± 0.15 Kg divided into three equal groups (D1, D2 and D3) following completely randomized design. Experimental diets were formulated by replacing ground nut cake (GNC) from the contr...

The effect of prolonged consumption of guar gum on iron absorption and Fe status was investigated in rats. Experiments with closed loops of duodenum, isolated in situ, were designed to reveal changes in the short-term regulation of duodenal Fe uptake, induced by challenge with low- and high-Fe meals. In separate experiments, the effect of guar gum on the capacity of intact rats to maintain Fe s...

Everted sacs of rat proximal small intestine were used to determine the effect of guar gum (5 g/l) on the uptake of cholesterol (0.1 mM) from a solution of micelles. The uptake of cholesterol was found to be linear both in the presence and absence of guar gum. When guar was present throughout the whole of the incubation medium, the uptake of cholesterol was reduced to approximately 40% of contr...

Introduction Consumption of low glycemic-index (LGI) foods has been shown to attenuate blood glucose response during the postprandial period immediately following a meal. In addition, positive metabolic effects can persist well beyond this period. One of these extended effects, known as the “second-meal effect,” is the positive effect of the bioavailability of glucose on the glucose tolerance o...

The present study describes the screening of different agroindustrial byproducts for enhanced production of alkaline protease by a wild and EMS induced mutant strain of Bacillus subtilis IH-72(EMS8). During submerged fermentation, different agro-industrial byproducts were tested which include defatted seed meals of rape, guar, sunflower, gluten, cotton, soybean, and gram. In addition to these m...

Hydrocolloids, often called gums that generally contain many hydroxyl groups and may be polyelectrolytes .Foams are colloidal systems in which tiny air bubbles are dispersed in an aqueous continuous phase. Many processed foods consumed daily are liquid or solid foams, such as the head of soft drinks and beer, whipped cream, mousses, meringue, bread and ice cream. The utilization of these gums d...
