Keywords: L-asparaginase, bat faeces, Staphylococcus aureus
Abstract: L-asparaginase activities of Staphylococcus aureus from bat faeces were investigated. Bat faeces samples were collected and subjected to plating. Interestingly all the samples showed the presence of S. aureus. Among the colonies formed, 10 staphylococcal isolates (I-X) were subjected to the assay and screening of L-asparaginase activity. Rapid plate assay on M-9 medium showed the formation of pink zones around each colony. Maximum zone diameter obtained was 1.5 mm in isolate V, whereas isolate VI exhibited maximum enzyme activity (21.55 g ammonia/ml/h) in Nesslerization method. IN Lowry ' s method, maximum protein content was obtained in isolate II (0.82 mg/ml). The optimum pH and temperature range for maximum enzyme activity was estimated as 7 and 370C, respectively.

Keywords: River Noyyal, pollution, physico-chemical characterization
Abstract: Increasing industrial development on the bank of River Noyyal poses a great risk to its ecology. To explore the extent of pollution level of Noyyal river, water samples were collected from five stations namely Boluvampatti, Perur, Alangadu, Kasipalayam and Orathupalayam and were analysed for the physico-chemical parameters. Results showed heavy contamination of Noyyal river towards the downstream stations as evidencec by acidic pH (6.1) at Kasipalayam, a high level of TDS (4533.3 mg/l) at Orathupalayam, zero levels of oxygen at Alangadu and Kasipalayam, increased levels of BOD (277.5 mg/l) at S5 and COD (278.7 mg/l) at S4, high levels of alkalinity (808.3 mg/l) at S4 and hardness (880 mg/l) at S3, elevated levels of chlorides (5798.3 mg/l) at Orathupalayam and Sulphate (74.7 mg/l) at S3.

Abstract: Lysosomal membrane responses in the tropical teleost-Oreochromis mossambicus exposed under laboratory conditions to water accommodated fractions (WAF) of Bombay High crude oil for three weeks was assayed. Lysosomes are subcellular organelles bounded by a semi permeable lipoprotein membrane contain a battery of hydrolytic enzymes. Total lysosomal activity for two acid hydrolases-acid phosphatase and ?- glucuronidase with different substrate specificities was determined in liver tissue of O. mossambicus. The results indicate that significant decrease (P<0.001) in lysosomal acid phosphatase and ?- glucuronidase whereas significant increase (P<0.001) in nuclear and soluble fractions. The response of the fish to WAF of crude oil was dose dependent.

Keywords: Land slide, erodibility, plant diversity, Sikkim
Abstract: The present study encompasses the analysis of vegetation types, its richness and studies of soil samples of four landslide prone areas of East Sikkim. The identification of dominant and effective plant species was done in each of four landslide areas. The investigation on various attributes of erodibility factor of soils have proved very high ' K ' values ranging from 0.08 to 0.18, indicating that the soils are excessively erodable. The categorized two active landslides Beto and Namli along with one presently passive landslide of Ganeshtok were confined within acidic zone (pH below 6). All the landslide prone areas were restricted mainly by nitrogen fixing plant species Alnus nepalensis. The dominance of particular tree species is not always supportive for managing the soil erodibility. The diverse tree species (12 in number) with dense canopy and higher representation of Poaceae (total raltive density: 30.64) enriched soil organic matter (3.27%) which comparatively lowered the erodibility (K=0.08) of presently passive landslide area Amdogolai. The study has endowed new foundation for utilizing preferable and landslide mitigating efficient plant species in landslide prone areas of Eastern Himalaya.

Abstract: Comparison of natural plant and callus extracts of Solanum xanthocarpum was studied against two bacteria and fungi, for their antimicrobial activity using cup diffusion method in various solvents such as chloroform, petroleum ether and ethanol. The leaf and stem segments of the plant were cultured on Murashige and Skoog basal medium supplemented with various growth regulators. Maximum callus was recorded on medium containing 0.5 mg/l NAA ( Naphthylacetic acid) and 0.5 mg/l kinetin. The results reveal that the stem and leaf callus extracts have been shown significant activity against the tested microorganisms compared to the natural sample.

Abstract: An investigation was carried out to assess the influence of different grades (size) of coir pith particles on growth and reproduction of the earthworm Eudrilus eugeniae. Earthworms were grown in the vermibeds of different size of coir pith particles (300, 750, 1250, 1750 and 2000?m). On the completion of the trail (90th day), the earthworms were examined in various life-stages. The population of earthworm was in the order: cocoons >juveniles>non-clitellates> adults. Highest biomass of earhtworm was recorded in the vermicompost containing the particle size 1250?m (1237 ?m as calculated). There was negative growth in the earthworms when grown in vermicompost containing coir pith of the size 2000 ?m and the worms could not survive in the vermibed containing 300 ?m coir pith particles.

Abstract: A survey was made in five important places of Trichirappalli city. Total of 120 fruits samples were collected from Chatram Bus Stand, Rockfort, Central Bus Stand, MG gate and Gandhi market region. They were analyzed for total viable count, fecal coliforms, enteropathogens and for common pathogens. Enterococcus fecalis was predominant (80%) followed by Escherichia coli (61.7%), Staphylococcus aureus 47.5%, Salmonella sp (34.2%), Shigella sp (44.2%), Vibrio (10%), Klebsiella (34.2%), Pseudomonas aeroginosa (40.8%) and TVC range was 4.4-12.8 x 104 CFU/g. As htis study revealed the potential hazardus of street vended fruits, need of vigorous washing of fruits with safe running water before consumption is inevitable to minimize the risk of food borne illness.

Abstract: Total protein, carbohydrate and lipid content of mantle, foot, digestive gland, hermaphrodite gland, albumen gland, dart and the snail flesh were estimated to assess the nutritional status of Cryptozona bistrialis. The protein, carbohydrate and lipid content of the whole animal were 73.6, 4.51 and 2.45 % respectively. Further, protein level was 46.85% in dart, 19.2% in foot, 42.10% in albumen gland, 29.8% in mantle and 32.5% in hermaphrodite gland. The carbohydrate level varied from 2.56% (mantle) to 4.72% (albumen gland) whereas the lipid from 1.04% (foot) to 2.31% (albumen gland). In general, the protein content was relatively high in the whole animal. Significant differences between values of protein, carbohydrate and lipid were noted.

Abstract: Protein-rich guava cheeses were prepared by blending guava pulp using soy protein isolate (SPI) and whey protein concentrate (WPC) in different concentrations ranging from 1% to 6% protein. The products were analyzed for nutritional and sensory characteristics. As the percentage of protein isolate increased above 3%, the sensory score decreased. The guava cheese fortified with 2% SPI or 2% WPC with TSS fo 80 Brix, 0.61-0.64% acidity, 63.28-69.76 mg/100 g ascorbic acid, 2.37-2.29% protein and an overall sensory score of 8.00-8.03 was found to be the best. The product was found to be nutritionally and microbiologically safe after six months of storage. According to the recommendation of ICMR, an ideal food should have 0.7-1.0 g/kg protein for adults and 1.2-2.0 g/kg for children. Hence, protein fortified guava cheese could be called as protein-enriched product suitable for both children and adults.
