Nowadays, the sorption-oriented approach is on agenda in remediation practices of lands contaminated with heavy metals. The current growing quantity research accounts for different sorbents. However, there still a lack studies utilizing economic criteria. Therefore, to ensure wide application opportunities, one necessary requirements their efficiency use. By these criteria, this manuscript rese...

OBJECTIVE To study the preparation of seeding type immobilized microorganisms and their degradation characteristics on di-n-butyl phthalate (DBP). METHODS Diatomite, clinoptilolite, silk zeolite, and coal fly ash were chosen as reserved materials and modified. Their adsorption capacity and intensity in the bacteria were determined and the best carrier was picked out. The seeding type immobili...

A quick, simple and improved DNA extraction method from polysaccharide rich leaves of Boswellia serrata Roxb. has been developed. Different methods involving use of CTAB and SDS with or without modification were used. A CTAB based extraction method which uses diatomite to remove polysaccharides, such as, gums and resin, proved to be the best. This method allowed recovery of good quality DNA in ...
