Taschenbuch. Condition: Neu. Neuware -Scientific Study from the year 2013 in the subject Biology - Micro- and Molecular Biology, grade: A, Nirma University (Institute of Science), language: English, abstract: Increasing applications of MW radiation has led to concerns globally due to the suspected bio effects associated with its… exposure. Effect of MW, thermal and/or athermal, is inconclusive, complex, and controversial in literature. Thermal effect causes thermogenic effect while athermal effects are other than heat and such effects reported as somatic effect and/or genetic effect.This study basically deals with the athermal effects and is aimed at investigating the hypothesis that the exposure of microbial cells to MW (low power) may cause athermal effect, which affect on growth of microbes, enzyme activity, and production of exopolysaccharides. Furthermore, we have also checked the effect of different intracellular enzymes on MW treated bacteria. Our study also gives information that MW athermal effects causes changes at genetic level and can be passed on to next generation.There are numerous and increasing applications of MW energy and technology in the industries, in homes, in medical, research institutions etc., and there is greater awareness and concern of the public over the suspected potential health hazards associated with such exposures [ICNIRP Guidelines, 1998]. There is therefore, a need for deeper understanding of the bio-effects of exposure to this radiation. Due to the ease of handing them in laboratory, microorganisms can be conveniently used to study the effect of MW on living systems. Besides, employing mutagenic frequencies of MW radiation for microbial strain improvement can be of considerable industrial significance.Objectives:1. To investigate the effect of low power MW ona. Growthb. Extracellular enzyme (amylase and pectinase) activity in Bacillus subtilis, Streptococcus mutans and Pectobacterium carotovora.c. Exopolysaccharide (EPS) in S. mutans and Xanthomonas campestris.2. To study the effect of low power MW ona. Growthb. Protein synthesisc. Intracellular enzyme (Glucose-6-phosphatase and ¿- galactosidase) activity3. To investigate mutagenic effect of MW on EPS production in X. campestris.

Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2013 in the subject Biology - Micro- and Molecular Biology, grade: A, Nirma University (Institute of Science), language: English, abstract: Hydrocarbon contamination of marine ecosystems has been a major environmental… concern. Hydrocarbon metabolizing capacity of four halotolerant bacteria (Bacillus atrophaeus, Halomonas shengliensis, Halomonas koreensis, and Virgibacillus salarius) isolated from saline soil of Khambhat, India was investigated. Presence of catechol metabolizing enzymes (catechol 2,3 dioxygenase, chlorocatechol 1,2 dioxygenase, and protocatechuate 3,4 dioxygenase) was checked in V. salarius, as only this among all the test organisms could grow on the hydrocarbon substrates used, and compared with Pseudomonas oleovorans. Effect of salinity of the growth medium on activity of catechol metabolizing enzymes was also studied. Catechol 2,3 dioxygenase activity in both the organisms was more susceptible to increase in salinity of the growth medium than chlorocatechol 1,2-dioxygenase activity. To thebest of our awareness, this is the first report of catechol metabolism in V. salarius. V. salarius was found to be capable of weak biofilm formation. As V. salarius is capable of growing at high salt concentration, alkaline pH, hydrocarbon degradation, and also of growth in presence of various metal ions, it can be an attractive candidate for bioremediation of marine oil spills. Organisms like V. salarius can also serve as a model for multiple stress tolerance in prokaryotes.

Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - Scientific Study from the year 2014 in the subject Biology - Micro- and Molecular Biology, grade: A, Nirma University (Institute of Science), course: M.Sc., language: English, abstract: This study attempted at microwave mutagenesis of: (i) Lactobac…illus plantarum for lactic acid overproduction, and (ii) Streptococcus mutans for reduced lactic acid production. Lactic acid is among the microbiological products with high market potential. Lactic acid is also an important virulence factor in formation of dental caries by S. mutans, as the acid produced by the bacteria leads to demineralisation of the teeth. Two of the mutants obtained (one from each organism) were able to maintain the altered lactic acid production till 10 generations. However the magnitude of alteration in lactic acid producing ability of the mutants went on decreasing over generations. The microwave effects observed in this study seem largely to be athermal in nature. Investigation of the mutants obtained at molecular level may result in identification of novel mutations responsible for altered lactic acid production. These mutations can then be introduced into a suitable organism either for better industrial production of lactic acid, or for constructing new probiotic strain(s) for possible application in maintenance of oral health.Effect of low power (90 W) microwave (2,450 MHz) radiation on bacterial growth and pigment production was studied in three different bacteria. Microwave exposure of 2-6 min duration was able to alter growth and pigment production (prodigiosin production by Serratia marcescens, violacein production by Chormobacterium violaceum, and staphyloxanthin production by Staphylococcus aureus) in the test organisms significantly. In this study, pigment production was estimated in the cell population originated from microwave treated inoculum, and not directly in the MW treated cells. Thus the alterations in pigment production and/or secretion might have been transferred from the originally MW treated cells to their daughter cells (who did not receive direct MW exposure), indicating the mutagenic influence of microwave radiation. Heavy prodigiosin overproduction observed in one of the test tubes inoculated with microwave treated S. marcescens could not be sustained by daughter populations corresponding to that tube, indicating the reversible nature of microwave induced mutation(s). The microwave effects observed in this study largely seem to be of athermal nature, as the thermal effect was minimized by use of ice during the microwave treatment.
