Keywords: Gibberellic acid, Sugarcane, Bacillus cereus, Carbon-nitrogen ratio.
Abstract: In this study, favorable carbon-nitrogen ratio for high yields of gibberellic acid (GA3) production from Bacillus cereus was investigated. First of all, optimum carbon (glucose, sucrose, maltose) and nitrogen (NH4CL, NaNO3, urea) sources among the others were chosen. The highest yield of GA3 productivity was found in growth medium supplemented with glucose (445.52+-0.45mg/L). NaNO3 was found as a suitable nitrogen source (424.18+-0.18 mg/L). Then, in order to determine the optimum carbon-nitrogen ratio, different concentrations of carbon (from 50 mM to 200 mM) and nitrogen (from10mM to 40 mM) sources were added in culture media. As a result, optimum carbon-nitrogen ratio for GA, production from Bacillus cereus was found to be 100:10 mM.

Keywords: Fruit Eating Bat, Pteropus giganteus, Frugivorous, Nectarivorous, Feeding ecology, Shivamogga.
Abstract: This paper deals with study of feeding activity of fruit eating bat (Pteropus giganteus) in Shivamogga area. The present investigation identified ten host plants for roosting and more than twenty different types of fruits preffered as food. They play an important role in the seed dispersal of fruit plants. They chew the fruit to obtain the juice. Very soft fruits such as bananas are swallowed, but spit out the fruit pulp and seeds once it has extracted all the juice. In the evening bats become increasingly active and at one point they take off and find a feeding place., often very far away from their resting places. Bats travel 40-50 Km per day around the nested area. They move to different places such as Thirthahalli, Agumbe, Sringeri, Kavishyla, Huncha, Heggargudda forest, Shettihalli forest near Mastikatte Reservoir, Tunga reservoir and Bhadra reservoir around Shivamogga. In the present study area bats mainly fed on 18 varieties of fruits. These food plants are available around the nesting area. During day time they were roost in various host plants such as Bamboosa valgeri, Samanea samana, Ficus bengalensis, Ficus religiosa, Artocarpus integraifalia, Pongamia pinnata etc. The hitherto study revealed around 1000 animals in six rookeries and there is an urgent need to create awareness among common public to protect these useful animals to maintain ecological balance.

Abstract: The prime purpose of this study was to screen secondary metabolites i.e, phytochemical analysis and to evaluate the antibacterial activity of methanolic extracts of Coriandrum sativum Linn. against 11 bacterial isolates belonging to 2 different genera of gram negative and gram positive bacterial population isolated from urine specimen by employing disc diffusion method. The phytochemical analysis was done to screen flavanoids, phytosterols, tannins, phenolic compounds, carbohydrate, fixed oils and fats, glycosides, resins and lignin. The methanolic extract of leaves of Coriandrum sativum showed maximum activity against Escherichia coli and Staphylococcus aureus. Coriandrum sativum was observed to have an potent antibacterial activity and can be used for medicinal purposes. In the present study, it was noted that Coriandrum sativaum has antibacterial activity and also there is presence of secondary metabolites in leaves of Coriandrum sativum.

Abstract: Textile effluent and sludge produced by effluent treatment plant is rich source of dye decolorizing bacterial population. Total 39 isolates on the basis of their Gram reaction, colony characteristics, and cell morphology. Samples contain both the types of organisms, Gm +ve and Gm -ve with sominated Gm +ve species. Initially, all 39 isolates were tested for their ability to decolorize two azo dyes, Reactive Black 5 and Green B. Then, six potential isolates were selected on the basis of their dye decolorizing ability and further tested with FF sky Blue, Black E, Black BT and Reactive Orange M2R. Differences in structures and complexity of the dye led to variable percentage of decolorization of different dyes by the same organism.

Abstract: The purpose of this study was to evaluate the efficacy of various extracts of stem of Cissus quadrangularis and fruits of Terminalia chebula against some food poisoning bacteria such as Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa and Escherichia coli. The antibacterial activity of different solvent extracts (ethyl acetate and methanol) of these plants was determined by using disc diffusion method. Results revealed that ethyl acetate extract of C.quadrangularis exhibited significant antibacterial activity against all the tested bacteria except P. aeruginosa. The methanolic extract of T.chebula showed maximum zone of inhibition against the bacteria B.cereus. From the present study it is clear that these two plants may have the potential to be used as natural medicine against food poisoning bacteria. However there is a need for further research to isolate the bio-archive compounds responsible for antibacterial activity.

Abstract: Karyotype analysis was performed on Gymnocorymbus ternetzi (Family: Characidae) by investigating the number and structure of its chromosomes. Metaphase chromosome spreads obtained from gill and tailfin epithelial cells and kidney were analyzed under low and high power of microscope and photographed. The diploid chromosome number of this species was 2n = 48 (n-24). The karyotype consist of 20 pairs of metacentric, 20 pairs of submetacentric, 6 pairs of sub telocentric, 2 pairs of telocentric chromosomes. The chromosomal information described here should be useful in monitoring gynogenetic population studies and hybridization in this species.

Keywords: Extrapulmonary tuberculosis, IS6110, Mycobacterium tuberculosis complex, Nested polymerase chain reaction (nPCR).
Abstract: Extrapulmonary tuberculosis (EPTB) is a significant health problem in both developing and developed countries. India is the highest tuberculosis burden country accounting for one fifth of the global incidence ranges between 8.3% and 13.1% in different districts. The aim of this study is to evaluate PCR as a rapid and sensitive tool for diagnosis of clinically suspected cases of Extra pulmonary tuberculosis. Two hundred samples of clinically suspected cases of EPTB were collected and processed for Mycobacteria by Ziehl-Neelsen staining and also for PCR amplification with primers targetting 123 bp fragment of insertion element IS6110 of M. tuberculosis complex. 65 samples were positive for M.tuberculosis complex by nPCR. Out of these 65 PCR positive samples, only 22 (68.75%) were ZN smear positive. We conclude that PCR assay targetting 123 bp fragment of IS6110 is a highly sensitive and specific test for rapid diagnosis of EPTBs.

Abstract: Enterotoxemia is the most important and wide spread disease of sheep and goats in India. The disease is usually per acute and acute and death occurs within hours after showing clinical symptoms of watery diarrhoea, abdominal pain, convulsion and recumbency. Enterotoxaemia is caused by Clostridium perfringens type D and under certain conditions the organisms multiplies rapidly and produces high concentration of epsilon toxin leading to toxaemia and death. Epsilon toxin is potent pathogenic Clostridium toxin. Epsilon toxin gene was amplified, sequenced and in silico analysis was attempted in this study. Primer specific for etx gene amplified a product size of 933 bp. C. prefringens type D strain IVRI49 etx gene sequences of this nucleotide sequence revealed that it has high hydrophilicity and consists of mainly beta pleated sheets secondary structures. This protein is predictably more immunogenic with less surface probability. This study will help in designing subunit vaccine and recombinant vaccine and also for diagnostic kit developments.

Abstract: Vermicomposting of vegtable wastes amended with cattle manure using earthworm species Eisenia Foetida was studied for a period of 45 days. The vegtable waste mixture had 45.15 ? 1.9 % organic carbon, 1.5 ? 0.21% total nitrogen and 30.1 ? 2.1 C:N ratio initially. Organic carbon and C/N ratio decreased in both the control and experimental pots whereas nitrogen content increased during the study period. Significant variation in total organic carbon, nitrogen content and C/N ratio (P<0.05) was observed on 15th, 30th and 45th day of composting.
