Windblown and water-induced erosion cause substantial soil losses worldwide, especially for drylands. Any sustainable management program that increases organic matter improves the stability of crustal layer could considerably enhance productivity preservation erosion-prone land. This paper presents a laboratory investigation cyanobacteria-inoculated medium sand fine soils studied severe runoff ...

This study characterized the types of interactions between Escherichia coli O157:H7 and spinach phylloepiphytic bacteria and identified those that influence persistence of E. coli O157:H7 on edible plants. A total of 1512 phylloepiphytic bacterial isolates were screened for their ability to inhibit or to enhance the growth of E. coli O157:H7 in vitro and on spinach leaf surfaces. Fifteen differ...

A fungal consortium including Aspergillus niger, Mucor hiemalis and Galactomyces geotrichum was tested for the treatment of dairy wastewater. The bio-augmentation method was tested at lab-scale (4 L), at pilot scale (110 L) and at an industrial scale in Wastewater Treatment Plants (WWTP). The positive impact of fungal addition was confirmed when fungi was beforehand accelerated by pre-culture o...

Enrichment cultures of microbial consortia enable the diverse metabolic and catabolic activities of these populations to be studied on a molecular level and to be explored as potential sources for biotechnology processes. We have used a combined approach of enrichment culture and direct cloning to construct cosmid libraries with large (>30-kb) inserts from microbial consortia. Enrichment cultur...

thyme (thymus vulgaris l.) is perennial aromatic shrub belonging to the mint family which has anti-spasmodic, antiseptic, carminative, anti-cough, sputum and antioxidant properties. in order to study the effects of drought stress and bio-fertilizer on plant growth, essential oil yield and constituents of thyme plant, an experiment was conducted in a split plot based on randomized complete block...
