this study was conducted to determine physiological and morphological variation of strains of the ectomycorrhizal fungus hebeloma cylindrosporum associated with pinus pinaster and its consequence on the symbiotic processes in coastal forests adjacent to bordeaux, south west france, from 2003-2005. mycelial cultures were conducted in the laboratory on a rich medium (ymg). diploid fungal strains ...

Luminescence in bacteria is catalyzed by luciferase. When these microorganisms are exposed to toxic substances, the bioluminescent enzyme system can be inhibited. The objective of this study was analyze potential that offer as native bioindicators coastal marine pollution. dynamics luminescence intensity visual classification and effect metal concentration on growth 25 strains luminescent bacte...

Halophilic archaea are known as the novel producers of natural products and their supernatant metabolites could have cytotoxic effects on cancer cells. In the present study, we screened the anticancer potential of supernatant metabolites from eight native haloarchaeal strains obtained from a culture collection in Iran. Five human cancer cell lines including breast, lung, prostate and also human...

5.1 Background Isolation of appropriate microbes is very essential before putting them through screening procedure. The initial step for isolation is to obtain the organism in pure culture without which, it cannot be considered for characterization. Enrichment of isolation culture is essential to isolate desired class of microorganisms where selective media is utilized for the pure culture of r...

Cloning and sequencing of a lipase gene from an indigenous Bacillus pumilus, strain F3, revealed an open-reading frame of 648 nucleotides predicted to encode a protein of 215 residues. Sequence analysis showed that F3 lipase contained a signal peptide composed of 34 amino acids with an H domain of 18 residues. A tat-like motif was found in the signal peptide similar to some other Bacillus pumil...

These digital natives typically gravitate toward group activities in technology embedded social contexts. However, despite this multidimensional evolution, little has changed in conventional classrooms where they build their education experienc...

This chapter analyzes the adequacy of two university education models according to their Information Communications Technology (ICT) usage: One model is based on the use of ICT as a cornerstone and a cohesive element of the teaching-learning process, whereas the other considers ICT a mere teaching support tool. The preliminary results obtained from a review of case studies reveal that ICT use i...

The New Zealand native legume flora are represented by four genera, Sophora, Carmichaelia, Clianthus, and Montigena. The adventive flora of New Zealand contains several legume species introduced in the 19th century and now established as serious invasive weeds. Until now, nothing has been reported on the identification of the associated rhizobia of native or introduced legumes in New Zealand. T...
