1. Alpha amylase and Alpha glucosidase inhibitory effects of aqueous stem extract of Salacia oblonga and its GC-MS analysis
ABSTRACT Our present investigation deals with the phytochemical screening, estimation of total flavonoids, terpenoids and tannin contents to evaluate the anti-diabetic activities of Salacia oblonga stem followed by GC-MS analysis. It explores the natural compounds and the potential α-amylase and α-glucosidase inhibitory actions of stem extracts. The aqueou

2. Biodegradation of kerosene: Study of growth optimization and metabolic fate of P. janthinellum SDX7
Penicillum janthinellum SDX7 was isolated from aged petroleum hydrocarbon-affected soil at the site of Anand, Gujarat, India, and was tested for different pH, temperature, agitation and concentrations for optimal growth of the isolate that was capable of degrading upto 95%, 63% and 58% of 1%, 3% and 5% kerosene, respectively, after a period of 16 days, at op

3. Hidrocarbonetos policíclicos aromáticos no meio ambiente: diferenciação de fontes em sedimentos e metabólitos em bile de peixes
Many studies on environmental ecosystems quality related to polycyclic aromatic hydrocarbons (PAH) have been carried out routinely due to their ubiquotus presence worldwide and to their potential toxicity after its biotransformation. PAH may be introduced into the environmet by natural and anthropogenic processes from direct runoff and discharges and indirec

4. Utilização de resíduos industriais como substratos de baixo custo para a produção de biossurfactante por Candida sphaerica
Surfactants are amphipathic agents with application in different industries, such as the petroleum, food and pharmaceutic. Many kinds of chemical surfactants are being used nowadays, although the development of alternative products, with biodegradable nature and lower toxicity, as the so called biosurfactants, metabolites from microorganisms, is a sound stra

5. Selective Removal of Nitrogen from Quinoline and Petroleum by Pseudomonas ayucida IGTN9m
Enrichment culture experiments employing soil and water samples obtained from petroleum-contaminated environments succeeded in the isolation of a pure culture possessing the ability to utilize quinoline as a sole nitrogen source but did not utilize quinoline as a carbon source. This culture was identified as Pseudomonas ayucida based on a partial 16S rRNA ge

6. T-2 metabolites in the excreta of broiler chickens administered 3H-labeled T-2 toxin.
A method for the detection of T-2 metabolites was developed and applied to analysis of metabolites in excreta of broiler chickens administered 3H-labeled T-2 toxin. The method used acetonitrile extraction and partitioning with petroleum ether followed by chromatography on Amberlite XAD-2, Florisil, and Sep-Pak C18. The recovery of T-2 toxin added to the chic

7. Sister chromatid exchanges in lymphocytes of petroleum retailers.
Occupational exposure to petroleum vapour was assessed in workers employed in suburban petroleum retail outlets. Urinary output of thioethers provided a non-specific estimate of exposure to chemicals metabolised via a mercapturic acid pathway. Urinary d-glucaric acid (DGA) excretion was taken as an estimate of hepatic enzyme activity. Sister chromatid exchan

8. Naphthalene biodegradation in environmental microcosms: estimates of degradation rates and characterization of metabolites.
Naphthalene biodegradation was investigated in microcosms containing sediment and water collected from three ecosystems which varied in past exposure to anthropogenic and petrogenic chemicals. Mineralization half-lives for naphthalene in microcosms ranged from 2.4 weeks in sediment chronically exposed to petroleum hydrocarbons to 4.4 weeks in sediment from a

9. Evidence for acetyl coenzyme A and cinnamoyl coenzyme A in the anaerobic toluene mineralization pathway in Azoarcus tolulyticus Tol-4.
A toluene-degrading denitrifier, Azoarcus tolulyticus Tol-4, was one of eight similar strains isolated from three petroleum-contaminated aquifer sediments. When the strain was grown anaerobically on toluene, 68% of the carbon from toluene was found as CO2 and 30% was found as biomass. Strain Tol-4 had a doubling time of 4.3 h, a Vmax of 50 micromol x min-1 x
