    Authors: Mangrio G.Sughra, Dahot, M. Umar and Simair, A. Ahmed

    Present study was carried out to utilize sugar industry byproduct (molasses) as a carbon source for the growth of different fungi and production of pectinase enzyme. Four types of fungi (P. lilacinum, M. geophillus, A. niger and A. fumigatus) were used in this study. The maximum production rate of pectinase was observed by A. niger when grown in 2.5% and 5% molasses in comparison to other fungi used. Highest rate of pectinase 10.13units/ml was produced after 72 hours when A. niger was grown on 5% molasses.

    This study was undertaken to investigate the effect of Garlic (Allium sativum) and Ginger (Zingiber officinale) aqueous extracts on serum glucose, cholesterol, urea levels and body weight in normal and alloxan-induced diabetic male rabbits. Before alloxan monohydrate (120mg/kg) introduction rabbits were left in fasting condition till twelve hours. After seven days of alloxan monohydrate induction diabetes mellitus was confirmed animals with fasting serum glucose level ? 250mg/dl and were considered as diabetes. In whole experimental work twelve male rabbits were selected divided in to four groups and each group contains three male rabbits 1st and 2nd group normal and diabetic control 3rd to 4th group containing male rabbits were treated with 1% garlic and ginger aqueous extract to check the comparison between them against serum glucose and their variable effects on serum cholesterol, serum urea and body weight. Blood serum was used to determine all selected biochemical parameters, on every third day. It was observed that 1% Garlic and ginger aqueous extract controlled 51% and 45.26% glucose, 35.29% and 21.95% cholesterol, 46.22% and 21.69% urea level and body weight gradually increased in alloxan induced diabetic male rabbits. It is observed in the present investigation that oral administration of garlic and ginger aqueous extracts are hypoglycemic agents but according to the results garlic is the best hypoglycemic agent, which also controlled cholesterol and urea level more than ginger in alloxaninduced diabetic male rabbits

    Microbial fuel cells (MFCs) are new bioprocess method for conversion of chemical energy in organic matters to bioelectricity. In some MFCs produced electrons can travels to anode surface directly and need some artificial component to transfer the produced electron to anode surface. This paper tries to highlight different mediators that have been used as electron mediators in the MFCs in recent years. In this research study, Escherichia coli ATCC 8739 was used for power production in an anaerobic condition. Methylene blue, thionine, humic acid, potassium fericyanide and neutral red at different concentrations (50 to 500µmoll-1 ) are selected and analyzed with several concentrations as mediators. Cyclic voltammetry use to study of anodic electrochemistry analysis. All experiment carry out in aerobic an anaerobic condition but at aerobic condition did not obtain significance peak. The obtained results demonstrate that NR has better ability for transfer of electron in this study.
