Asian Journal of Advances in Research, Page 6-12

Microbial Fuel Cell is a promising tool that utilizes microorganisms as biocatalysts to transform chemical energy into electrical energy. The particular microbe is able to utilize different substrates via metabolic activity resulting in the generation of electric current. The reason for the growing popularity of MFC is due to its multifaceted applications attributed to its eco-friendly nature. Even though the current generation is in milliampere (mA) scale, MFCs have unlimited benefits for future purposes. Fungi are among the microorganisms able to generate electricity as a result of their metabolic processes. The microorganism used in this study is Saccharomyces cerevisiae (baker’s yeast). Electrons are diverted from the electron transport chain of this single-celled eukaryote which therefore helps in the conversion of chemical energy into electrical energy. The point of this examination is to measure the amount of electric flow produced by Saccharomyces cerevisiae, when using copper electrodes with mediator and sources of a substrate on the production of current. For the reaction to be carried out, Potassium permanganate (KMnO4) was used as a mediator. The best results (105.3 mA) were obtained from maltose as substrate. Thus, here we describe the main findings, which can be used as the starting point for future investigations. We show that fungi have the potential to act as electrogens.

Asian Journal of Advances in Research, Page 13-20

Water quality of Anasagar lake was studied for period of four months on the basis of fortnightly sampling. This study has provided the first data set for water quality of lake. The value of various physico-chemical parameter were temperature (24.50°C to 33.90°C), pH (7.9 to 8.2), electrical conductivity (2.07 to 2.49 mS/cm), dissolved oxygen (7.53 to 8.73 mgL-1), alkalinity (101 to 109 mgL-1), Hardness (121 to 150 mgL-1), total dissolved solid (1344.00 to 1617.00 mgL-1), nitrate (0.88 mg L-1 to 1.02 mgL-1), phosphate (0.67 mgL-1 to 0.76 mgL-1), depth of visibility during the study period was 48.92 cm. Anthropogenic stressors such as disposal of raw sewage and municipal wastewater, input of detergents due to washing of clothes and bathing, inputs of pesticides and chemical fertilizers due to unsustainable agriculture, aquaculture and horticulture, and urban settlement have forced the lake into the severely polluted and hyper-eutrophic condition.

Asian Journal of Advances in Research, Page 21-27

The aim of this experiment was to evaluate the proximate, mineral, vitamin and amino acid composition of Prosopis africana seed oil (PASO). The proximate revealed the presence of moisture (5.62%), crude protein (30.71 %), crude fibre (6.47%), ash (5.08%) and energy (383.26 Kcal/g). Mineral analysis of PASO showed that it contains calcium, potassium, potassium, magnesium, sodium, manganese, zinc, copper and iron at 403.8 mg/100g, 606.1 mg/100g, 142.8 mg/100g, 281.3 mg/100g, 101.7 mg/100g, 38.56 mg/100g, 19.10 mg/100g, 42.28 mg/100g and 14.93 mg/100g respectively. Amino acid such as lysine (4.18 g/100g), histidine (2.31 g/100g), arginine (4.85 g/100g), aspartic acid (8.61 g/100g), threonine (2.80 g/100g), serine (3.11 g/100g), glutamic acid (11.44 g/100g), proline (3.29 g/100g), glycine (3.47 g/100g), alanine (5.22 g/100g), cystine (1.08 g/100g), valine (4.72 g/100g), methionine (1.40 g/100g), isoleucine (3.22 g/100g), leucine (8.31 g/100g), tyrosine (2.40 g/100g), tryptophan (0.90 g/100g) and phenyl alanine (3.85 g/100g) were found to be abundant in PASO. Vitamin analysis of the test material shows that vitamin E had the highest concentration of 11.67 mg/100g followed by vitamin C (8.56 mg/100g), vitamin A (0.55 mg/100g), vitamin D (0.33 mg/100g), vitamin B3 (0.25 mg/100g), vitamin B1 (0.21 mg/100g), vitamin B12 (0.20 mg/100g), vitamin B6 (0.18 mg/100g), vitamin B5 (0.10 mg/100g), vitamin B2 (0.08 mg/100g), vitamin K (0.08 mg/100g) and vitamin B9 (0.06 mg/100g) respectively. It was concluded that PASO is rich in several nutrients that have numerous health benefits including tissue maintenance, coordination of body functions and other biochemical and physiological functions in the body.

TOXICITY ACTIVITIES OF Jatropha curcas SEED EXTRACT AGAINST THE 4TH INSTAR LARVAE AND PUPAL STAGES OF Aedes aegypti

Asian Journal of Advances in Research, Page 28-32

Mosquitoes are vectors of several diseases of public health importance. Their control with synthetic insecticides has faced challenges of resistance by target insects and consequent environmental pollution. There is therefore need to find alternative ecofriendly plant derived insecticide. Therefore toxicity activities of Jatropha curcas seed extract against the 4th instar larvae and pupal stages of Aedes aegypti was studied in vitro with increasing doses of Jatropha curcas seed extract for 96 hours. The result showed significant difference between mortality among treated animal and control (P< 0.05). Mortality of both larvae and pupae of Aedes aegypti treated with Jatropha curcas seed extract was dose and time dependent. At the highest (9%) concentration (wt/vol), mean larval mortality was 100%, while at the lowest (1%) concentration, the mortality decreased to 50%. Mean pupal mortality increased to 100% at highest concentration of 9% (g/100ml) but decreased to 40% at lowest concentration. The duration of incubation also influenced mortality. At 72 and 96 hours of incubation all treated larva died in highest concentrations of the extract (9% and 7%) while the entire treated pupa died out in 96 hours of incubation at the highest concentration (9%) of the extract. Survived larva and pupa after 96 hours in lower concentration could not develop to adult stage. In conclusion Jatropha curcas seed water extract has toxicity effects on larvae and pupae of Aedes aegypti and can be deployed for the control of the insect.

Asian Journal of Advances in Research, Page 1-5

After independence in our country, paper industries has bright future but at the this century, large amount of paper is required. Due to this reason , paper industry has bright future, for this purpose forest cover TREE-PLANTATION, must be done. From forest, we get food, fodder, fuel, Pharmaceutical-products,, vitamins, pure air, & stoppage of floods etc.
