In the preliminary stage the Enterobacter cloacae GNTEW13-1 and GNTEW13-V has grown on the glycerol based medium to enhance the more utilization of glycerol for the high production 1, 3-propanediol. Total 10 mutants were screened after UV Treatment and among these mutants, 3 mutants showed increased production over parent strains.

The conversion of glycerol may be carried out by both chemical as well as biological means.
Many microorganisms are known to convert glycerol to value added industrially important products. The present study involved the isolation of potent bacterial strains from soil sample obtained from bio-diesel information and demonstration center, Gulbarga University, Gulbarga, Karnataka, India. The isolated strain was Enterobacter safensis and is designated as GNTEW-13. As the Enterobacter safensis strain is the known producer of 1,3-PDO, is an important component of fuel and polyesters (used widely in the petroleum industry) using bio-diesel derived crude glycerol for producing 1,3- Propanediol, which is a substituent in various industrial sectors as good and remarkable solution from an commercial as well as ecological point of view.

The aim of present study is to investigate on the concentration of heavy
metals (Cu, Ni, Fe, Co, Mn, Cr and Zn) present in the water and their
effects on Toxicity, Hematology, Gravimetric and Serum biochemistry
of healthy albino rats. The results showed that 50% of toxicity and
there was significant difference (p<0.05) in the Red Blood Cell (RBC)
and White Blood Cell (WBC), It indicate the hemolytic anemia. This is
due to injurious effect of the toxic heavy metals of water. Where in
case of Gravimetric study the average weight reduced significantly
(p<0.05) in test rats when compared with control, indicating that, the
excess heavy metal water exposure to rats caused reduction in weight
of liver, heart, kidney and adrenal. The serum biochemistry studies of
protein, cholesterol, urea, and phospholipids were reduced in all the
groups studied. Thus, it can be concluded that heavy metals of water as serious consequences
on toxicity, hematology, Gravimetric, Tissue and serum biochemistry in rats and causes
hemolytic anemia which is attributed to the toxic effect of heavy metals of the water in the
experimental rats.

potentials for its seed oil, which can be converted into biodiesel- an alternative to petro-diesel. It aims to overcome
energy crisis problem and also to reduce environmental changes. The fact that the oil of J. curcas cannot be used for
nutritional purposes without detoxification makes its use as an energy source for fuel production very attractive. Oil
content of Jatropha curcus L was subjected to various physicochemical parameters. The chemical parameters include
determination of free fatty acids, peroxide value, Iodine value, saponification value, various physiological analysis of
Jatropha curcus L plant was also carried out in order to estimate the presence of total content of chlorophyll. By
considering all the above parameters the present study reveals that the Jatropha curcus L l plant is good for production
of better quality of biodiesel.

The rats were divided into four groups and were fed with Bheema river water subsequently for one day, four day and seven day. The rats of control group received only normal tap water, where as group one, group two, and group three were fed with Bheema river water for one day four day and seven day. The rats treated for two days have shown significant reduction in the Hemoglobin content and, differential counts compared to other group. Simultaneously we have checked the various physical and chemical parameters of Bheema river water where we observed significant variations in the chemical analysis of the water quality compare to normal water which shows that the Bheema river water is polluted and not good for drinking purpose.

This study investigated different solvent extracts of Zingiber officinale, to determine their efficacy against multidrug resistant microbes. The antimicrobial properties of various extract of Zingiber officinale (ginger) against Escherichia coli and Klebsiella pneumoniae that are common causes of gastrointestinal tract infection were investigated using the Agar and tube diffusion method. The results obtained revealed that Methanolic extract of ginger gave the widest zone of inhibition against one out of the two test organisms at the concentration of 20 mg mL -1 . However, Klebsiella pneumonia was more sensitive to the extract. It was also observed that the solvent of extraction and its varying concentrations affected the sensitivity of the two test organisms to the plant extract showing that ginger has antimicrobial activities on the test organisms due to its inhibitory effect, thus confirming its use in folk medicine.
