We simulate the dynamics of a suspension of bacterial swimmers, which chemotactically sense gradients in either ambient or self-secreted attractants (e.g. nutrient or aspartate respectively), or in both. Unlike previous mean field models based on a set of continuum partial differential equations, our model resolves single swimmers and therefore incorporates stochasticity and effects due to fluc...

The debate about the importance of bacterial infection in chronic obstructive pulmonary disease will continue. About half of exacerbations yield positive sputum bacteriology, and the isolation rate can be increased by selection of purulent samples. However, bacteria are also isolated in the stable state. The presence of bacteria in sputum alone during an exacerbation does not prove causation. B...

Nucleic-acid based methods for bacterial identification are extremely useful in diagnostic applications due to their specificity and sensitivity. However, they require an optimal purification of the target molecules. As part of the development of a new diagnostic method for the detection of bacterial RNA in cow milk, we have compared four commercially available RNA extraction kits for the isola...

Phospholipid-derived fatty acids (PLFA) and respiratory quinones (RQ) are microbial compounds that have been utilized as biomarkers to quantify bacterial biomass and to characterize microbial community structure in sediments, waters, and soils. While PLFAs have been widely used as quantitative bacterial biomarkers in marine sediments, applications of quinone analysis in marine sediments are ver...

The trial was carried out in agriculture field, Karaikal during the season of June- September to test efficacy isolated bacterial endophytes from roots brinjal as microbial inoculants seeds along with inorganic fertilizers soil on growth, yield and some biochemical constitutions (Solanum melongena L.) considering constitutions, data revealed that maximum parameters were recorded T6 results show...

Abstract: IAC 2051 is a common bean (Phaseolus vulgaris L.) cultivar with carioca-type seed coat, mean 1000 weight of 300g, indeterminate semi-upright type II growth habit, slow post-harvest coat darkening, resistance to Fusarium wilt, bacterial blight, and three races anthracnose, yield 2729 kg ha-1.

aimed at reducing the consumption of chemical fertilizers on crop production and according to important role of micro-nutrients such as iron, on increase performance of these products, nanocomposites effect of iron on yield and yield components of wax bean genotypes inoculated with rhizobium bacteria during experimental factorial randomized complete block design with three replications was cond...
