One of the major interests in soil analysis is the integrated evaluation of soil properties, which might be indicators of soil quality. Unsupervised methods of multivariate statistics are powerful tools for this integrated assessment and can help soil researchers to extract much more information from their data. A multivariate study was carried out in three farms from Guaı́ra, State of São Paulo...

A statistical method was developed to test for equivalence of microbial communities analysed by next-generation sequencing of amplicons. The test uses Bray-Curtis distances between the microbial community structures and is based on a two-sample jackknife procedure. This approach was applied to investigate putative effects of the antifungal biocontrol strain RU47 on fungal communities in three a...

This page within the Green Chemistry Resource Exchange describes an award-winning technology to produce 1,3-propanediol using an engineered Escheri-chia coli strain. The process is now operating at a scale of 100 000 000 pounds, thus supplying this compound as a commodity chemical. Protection Agency's 2010 small business Green Chemistry award for developing innovative technology to make alkanes...

Passage of agricultural runoff through vegetated drainage ditches has been shown to reduce the amount of pesticides, such as atrazine, exiting out of agricultural watersheds. Previous studies have found that microbial communities in soil from fields treated with atrazine display enhanced rates of atrazine degradation. However, no studies have examined the potential for atrazine degradation in d...

The reaction mechanism for the phosphotriesterase from Pseudomonas diminuta has been examined. When paraoxon (diethyl 4-nitrophenyl phosphate) is hydrolyzed by this enzyme in oxygen18-labeled water, the oxygen-18 label is found exclusively in the diethyl phosphate product. The absolute configurations for the (+) and (-) enantiomers of 0-ethyl phenylphosphonothioic acid have been determined by X...

Chile is the second largest global producer of farmed salmon. The growth salmon production has not been free environmental challenges, such as increasing use pesticides to control parasitic load sea lice Caligus rogercresseyi. lack specificity can potentially affect non-target organisms, well structure and functioning aquatic ecosystems. aim this study, was understand effect on natural microbia...

Abstract Background Gray blight is among the most destructive diseases that affect tea plants worldwide. In this study, microorganisms from deep-sea sediment samples for those with antagonistic effects were screened against gray caused by Pestalotiopsis theae . Results Thirty-two and twenty-eight morphologically different bacteria fungi isolated, respectively. Isolates B5 A65 clearly inhibited ...

Ecologically sustainable agricultural practices are essential to ensure food security, and efficient agriculturally beneficial microbes (microbial inoculants) are playing potential role in sustainable crop production due to their immense plant growth promoting attributes, better adaptability to survival under stresses, and other uses that result in attenuating the pesticides/fertilizers use in ...
