Seasonal changes in soil moisture, soil temperature and C input from crop roots, rhizosphere products and crop residues can have a large effect on soil microbial biomass and its activity. The objective of this study was to quantify the seasonal changes in soil microbial biomass and the enzyme activity in soils under cultivation and barren lands. Soil samples were taken at four different seasons for two years of study. Significant differences were found between soil sampling periods for microbial biomass, Mineralizable C and enzyme activity. Microbial biomass C in summer season compared to post monsoon season arable land and barren land averaged 61.4, 55.3 % respectively. Mineralizable C was higher in soils under arable lands, possibly due to more flows of C and N to soils. During post monsoon season Urease activity is higher whereas no Amidase activity in all samples. During summer season both the enzyme activities were reported higher may be due to more favorable weather conditions (moisture and temperature) and fertilization increased soil enzyme activity. © Global Science Publications.

Analyzing antibiotic susceptibility pattern of Uropathogens helps to overcome the therapeutic difficulties created by the emerging antimicrobial resistant bacteria and guides in choosing appropriate empirical therapy. The aim of the study is to understand the susceptibility patterns of the uropathogens which assists in choosing the empirical therapy for UTI. Midstream urine samples were collected cultured and subjected to microscopical and appropriate biochemical tests for proper identification. Antimicrobial sensitivity tests were carried out by disc diffusion technique using Muller Hinton Agar. High level resistance is seen to Cotrimoxazole, Ciprofloxacin, Ceftazidime and Cefixime. Amikacin was found to be more effective against the isolates. Most of the isolates were sensitive to ceftriaxone sulbactam. From our study, Amikacin is recommended Urinary tract Infections as Empirical treatment.

Nutrition research concentrated on nutrient deficiencies and impairment of health. The advent of genomics-interpreted broadly as a suite of high throughput technologies for the generation, processing, and application of scientific information about the composition and functions of genomeshas created unprecedented opportunities for increasing our understanding of how nutrients modulate gene and protein expression and ultimately influence cellular and organismal metabolism. Nutritional genomics (nutrigenomics), the junction between health, diet, and genomics, can be seen as the combination of molecular nutrition and genomics. The diverse tissue and organ-specific effects of bioactive dietary components include gene-expression patterns (transcriptome); organization of the chromatin (epigenome); protein-expression patterns, including posttranslational modifications (proteome); as well as metabolite profiles (metabolome). Nutrigenomics will promote an increased understanding of how nutrition influences metabolic pathways and homeostatic control, how this regulation is disturbed in the early phases of diet-related disease, and the extent to which individual sensitizing genotypes contribute to such diseases. Eventually, nutrigenomics will lead to evidence-based dietary intervention strategies for restoring health and fitness and for preventing diet-related disease. In this review, we provide a brief overview of nutrigenomics from our point of view by describing current strategies, future opportunities, and challenges. © 2011 Trade Science Inc. - INDIA.

The production of gluconic acid with respect to varying substrate concentrations in submerged (SmF), surface (SF) fermentations was analyzed. Under the various fermentation conditions the biomass and specific growth rate varied with different concentrations of glucose. The effects of pH, temperature, incubation time and concentrations of carbon were tested in submerged fermentation process in production of gluconic acid by Aspergillus spp. The highest level of gluconic acid was obtained under SmF conditions. In all cases the maximum degree of gluconic acid conversion was observed at on initial substrate concentration of 10gm/100ml. The rate of glucose uptake increased on increasing the initial glucose concentration and glucose utilization was observed to be highest in the SmF process and was comparable with the SSF and SF processes. Themaximumrate of cell growth was obtained in all processes at an initial glucose concentration of 10gm. But in comparison to glucose, sucrose ismore effective than glucose. The gluconic acid production and change in pH were analyzed at varying time intervals and it was observed that the SmF and SF processes were completed within 5 days of incubation whereas the highest yield was observed after 3rd day of incubation and continued thereafter in the SmF process. The increase in production of gluconic acid corresponds to the increase in cell growth instead of Glucose Oxidase (GOD) activity. © 2011 Trade Science Inc. - INDIA.
