Proteases have been isolated from A. niger isolates originally isolated from common carp (Cyprinus carpio). The three isolates showed slight difference in their productivity of the enzyme. The characteristics of the enzyme from three isolates however was same i.e. alkaline in nature. The alkaline proteases are industrially very important.

The sambar (Rusa unicolor) is the largest and most widely distributed deer in India. Between July 2010 and June 2011, habitat utilization of sambar, using fecal pellet method was studied in VanVihar Naitonal Park, Bhopal, Madhya Pradesh, India. Sambar utilized different habitats in different seasons. Grassland and savanna habitats were overutilized in monsoon and post-monsoon while as wetland and woodland habitats were underutilized. In winter season, scrubland and grassland habitats were overutilized while as wetland habitats were underutilized. In summer season woodland and scrubland habitats were overutlized while as grassland, wetland and savanna habitats were underutilized by the sambar deer.

This study evaluated the present status of river Betwa by using Zooplankton as bioindicators. Standard methods were applied and Zooplanktons population size was correlated with biotic and abiotic parameters (physic-chemical). The species of planktonic protozoans, rotifers, cladocerens, copepods and ostracods were found in all samples. Result of the study indicated that potentiality of Zooplankton as bioindicator is very high.

Hemicellulose hydrolysate from acid- and alkali-impregnated wood chips of Ailanthus excelsa, a lignocellulosic substrate, was obtained using heating devices, namely, autoclave and microwave. Effects of various combinations of physical and chemical conditions on pretreatment was assessed based on release of hemicellulose hydrolysate from wood chips and yield of reducing sugars and ethanol from the hemicellulose hydrolysate. The various hydrolysis conditions tested were dilute acid- (0.7% sulphuric acid) or alkali- (3% sodium hydroxide) impregnated wood, two heating devices (autoclave and microwave), either singly or in combination, and single- or two-step hydrolysis process. Single-step acid hydrolysis applying microwave and autoclave as heating method gave almost similar results. The single-step autoclave-mediated dilute acid hydrolysis was chosen as optimal because it yielded the highest amount of pentoses (280 mg g-1) and total sugars (285 mg g-1). Hemicellulose hydrolysate after detoxification was found to be fermentable to ethanol (9.8-10.8 g L-1) by pentose-fermenting yeast, Scheffersomyces stipitis. Ailanthus excelsa may therefore be a potent tree for bioethanol production. © Forest Research Institute Malaysia.

Of the twenty-three morphotypes of yeasts isolated from soil capable of utilizing pectin as sole carbon source at 6°C, two yeast isolates, one psychrotolerant (PT1) and one psychrophilic (SPY11), were selected according to their ability to secrete pectinolytic enzymes under some oenological conditions (temperature 6 and 12°C and pH 3·5) and ability or inability to grow above 20°C, respectively. As compared to their optimal activity, the three pectinolytic enzymes viz., pectin methyl esterase (PME), endopolygalacturonase (endo-PG) and exopolygalacturonase (exo-PG) isolated and assayed at pH 3·5 from PT1 were found to retain 39, 60 and 60% activity at 12°C and 40, 79 and 74% activity at 28°C, respectively. Likewise, the enzymes PME and endo-PG at pH 3·5 from SPY11 displayed 46 and 86% activity at 12°C and 50 and 60% activity at 28°C, respectively. All these enzymes showed 20-90% of residual activity at pH 3·5 and 6°C. The yeast isolates PT1 and SPY11 were identified as Rhodotorula mucilaginosa and Cystofilobasidium capitatum, respectively, on the basis of morphological, physiological and molecular characteristics. This study presents the first report on pectinolytic activities under major oenological conditions from psychrotolerant isolate R. mucilaginosa PT1 and psychrophilic isolate C. capitatum SPY11.© 2013 The Society for Applied Microbiology.

Twenty nine isolates of black yeasts isolated from different environmental sources such as soil, water and different plant parts (diseased wood, leaf, flower and fruit). Their preferable niche has been found to be leaves followed by other plant parts. They were less frequent in other ecosystem studied. This is the first report about the ecological survey of black yeast in Bhopal.

Indiscriminate use of chemicals regardless of climate, soil vigor and other factors has adversely affected the environmental quality and soil ecosystem. Fungi play a key role in maintaining the biogeochemical cycles in the soil by utilizing many recalcitrant chemical compounds and some common insecticides. In the present study, many fungal species were isolated from the rhizosphere of Juglans regia L. in the Northern regions of Jammu and Kashmir, India and tested in thisinsecticide utilization-screening programme. Among the isolated strains, only Trichoderma koningii, Penicillium notatum, Aspergillus terricola and A. niger were successful in degrading the supplemented insecticides viz., dimethoate and pyrethroid. The strains exhibited the optimal growth in the temperature range of 20-300C. The two insecticides were providedas the sole source of carbon and nitrogen in the Potato Dextrose Agar (Hi Media). Trichoderma koningii used dimethoate as carbon source at a faster rate compared to that of pyrethroid as the nitrogen source. However, Penicillium notatum andAspergillus niger used dimethoate both as carbon and nitrogen sources. Trichoderma koningii and Aspergillus niger utilized pyrethroid as carbon source more vigorously than Penicillium notatum and Aspergillus terricola.

Metal complexes of general composition [M(L)2]X2 (where M = Cu(II) and X = Cl-, NO3 -) and [M(L)2]X3 (where M = Fe(III) and X = Cl-, NO3 -) were synthesized by the condensation of metal salts with semicarbazone (La)/thiosemicarbazone (Lb) derived from 2-acetyl benzofuran. The ligands and metal complexes were characterized by NMR, elemental analysis, molar conductance, magnetic susceptibility measurements, IR, atomic absorption, and electronic spectral studies. On the basis of electronic, molar conductance and infrared spectral studies, the complexes were found to have tetrahedral geometry. The Schiff bases and their metal complexes were tested for their antioxidant, radical scavenging and antibacterial activities. © 2013.

Objective: The aim of the present work was to assess the total phenolic content (TPC), total flavonoid content (TFC), and total alkaloid content (TAC) of crude hydro-methanolic seed extract of Abrus precatorius L. which is one of the beautiful seed bearing plant belonging to family Fabaceae and used extensively in many Ayurvedic preparations with significant therapeutic significance. Methods: The amount of total phenols was analyzed using Folin–Ciocalteu assay, the amount of total flavonoids by aluminum chloride assay and total alkaloids by bromocresol green-complex assay. Results: The TPC, TFC, and TAC of the hydro-methanolic seed extract were 219.966±4.714 mg gallic acid equivalent per gram, 73.333±2.357 rutin equivalent per gram, and 41.666±4.784 atropine equivalent per gram, respectively. Conclusion: The result of the study highlighted a potent phenol, flavonoid, and alkaloid contents in the crude extract and thus can be used to explore new drugs. The study also justifies some of the medicinal properties of the plant. © 2016, Asian Journal of Pharmaceutical and Clinical Research. All rights reserved.

Dichlorvos, a broad spectrum Organophosphate insecticide is a potential toxic pollutant, adversely affecting the fauna of aquatic ecosystem. The objective of the present work was to evaluate the acute toxicity and behavioral responses of Dichlorvos on Labeo rohita under static conditions. The median lethal concentration of the insecticide was found to be 16.71ppm and one tenth of LC 50 (1.67ppm) was studied for sub acute studies. Data obtained from the Dichlorvos acute toxicity tests were evaluated using Finney's Probit Analysis statistical method. Behavioral patterns were studied in lethal (1, 2, 3 & 4 d) and sublethal concentration (1, 5, 10 & 15 d). The test fish showed erratic swimming, increased surfacing, copious mucus secretion, loss of equilibrium and hitting to the walls of test tank before finally sinking to the bottom just before death. Fish under sublethal concentration were found under stress, but that was not fatal.
