The control of energy metabolism is fundamental for cell growth and function and anomalies in it are implicated in complex diseases and ageing. Metabolism in yeast cells can be manipulated by supplying different carbon sources: Yeast grown on glucose rapidly proliferates by fermentation, analogous to tumour cells growing by aerobic glycolysis, whereas on non-fermentable carbon sources metabolism shifts towards respiration.

The ability of the hyperthermophilic archaeon Sulfolobus solfataricus P2 to grow on organic and inorganic sulfur sources was investigated. A sulfur-free mineral medium was employed with different sources of carbon. The results showed that inorganic sulfur sources display growth curve patterns significantly different from the curves obtained with organic sulfur sources. Combustion of fossil fuels leads to the atmospheric emission of sulfur oxides that contribute to acid rain and air pollution.

Studies on the effect of different nutritional compounds on antibiotic activity revealed that the highest antibacterial activity was obtained when 1% starch (w/v) was used as the sole carbon source along with mineral trace elements. Extraction and purification of TBG19NRA1 culture supernatant led to the isolation of a pure molecule with good antibacterial activity. The compound has been identified as the cyclic polyether lasalocid A on the basis IR, MS and 13C NMR data interpretation and comparison with reference data from literature.

Species of the genus Halomonas are salt-tolerant organisms that have a versatile metabolism and can degrade a variety of xenobiotic compounds, utilizing them as their sole carbon source. In this study, we examined the genome of a Halomonas isolate from a hydrocarbon-contaminated site to search for chemosensory genes that might be responsible for the observed chemotactic behavior of this organism as well as for other responses to environmental cues.

ZSM-5 zeolite material (Si/Al ratio = 25) was synthesized with silica source of TEOS and TPAOH template. The zeolite is modified into proton form (HZSM-5) with 343 m2 /g of BET surface area, 324 m2 /g of micropore area, 0.1491 cm3 /g of micropore volume and 5.77 nm of BJH adsorption average pore width. Zinc oxide and iron oxide are dispersed onto HZSM-5 catalyst surface with different contents by wet impregnation method. The results of HZSM-5, Zn/HZSM5, Fe/HZSM-5 catalyst materials still retain the micropore structure of ZSM-5 zeolite.

In this paper, the thermal model of butt joint in Gas Metal Arc Welding (GMAW) is constructed and simulated based on ANSYS software to obtain welding temperature field. Low carbon steel with temperature-dependent thermal properties due to very high welding temperature is considered. Volumetric heat source is determined through series equations for different welding conditions.

The effect of different nitrogen sources on cell growth and polyhydroxyalkanoate (PHA) accumulation by halophilic bacterium strain Yangia sp. ND199 was investigated. The combination of 0.5 g/L potassium nitrate (KNO3) and 0.5 g/L yeast extract was shown to be good nitrogen source for cell growth and PHBV production by Yangia sp. ND199.

Mycelial growth and exopolysaccharide production of Fomitopsis feei was studied in common production medium by changing different physiological parameters such as carbon, nitrogen sources, inoculum size, incubation time, pH, temperature, agitation. Glucose, ammonium sulphate, 6mm of inoculum, 8th and 14th days of incubation, pH 3, 30°C temperature and 150 rpm agitation were the best for the production of mycelium.

This study aimed to finding best carbon and nitrogen sources that would allow maximum growth and antibiotic production of P. fluorescens AS15 for improving its bio control potentiality against banded leaf and sheath blight pathogen. The growth medium has a profound effect on growth and active metabolite production. The accurate incorporation of nutrients enhanced growth as well as antagonistic behavior of bio control agents (Slininger et al., 1996).

Twenty Five lignolytic fungi were isolated from decaying wood samples and were screened for the laccase production using guaiacol and ABTS as indicator compounds. The positive isolates were confirmed for the presence of laccase using Azure B and quantitative enzyme assay in presence of catalase using ABTS as substrate. Further laccase producing capacity of fungus was estimated in seven different media where Czapex Dox medium showed highest enzymatic activity of 17.2 U/ml.

This study was aimed to investigate the potential of single culture of fungi Aspergillus niger, to decolorize reactive dyes from synthetic solution. Different parameters such as pH, time, temperature, agitation rate and various carbon, nitrogen and inorganic salts source, were optimized for decolorization of reactive blue 19 and reactive black 5 dyes. Aspergillus niger showed maximum dye decolorization under optimum condition and found to be more efficient when added in the dye solution of pH 8 and 10 with agitation at 130 rpm and incubation time for 7 days with 25°C.

Soil organic carbon (SOC) pool is the largest among the terrestrial pools. The restoration of SOC pool in arable lands represents a potential sink for atmospheric CO2. The management and enhancement of SOC is important for sustainable agriculture. The cropping system and soil type influence crop biomass under different fertilization. Agriculture acts as both the sink and sources of the greenhouse gases.

A lab experiment was conducted at the department of microbiology, G. B. Pant University of Agriculture & technology, Pantnagar. MPS activities were measured in liquid media (NBRIP broth) using Ammonium sulphate as N source, glucose and maltose as a carbon source at 10oC. Glucose significantly increased MPS activity and this activity was three times (3610.12PPM) in comparison of maltose (1434.99PPM). The mineral phosphate solubilizing activity was strongly associated with the production of gluconic or citric acids.
