Dialkylfluorophosphatases of microorganisms.
Organisms were grown for periods varying from 20 to 48 hours in a peptone-yeast extract-glucose medium buffered at pH 6.8 to 7.0 with 0.05 Y phosphate buffer. Representative types which grew satisfactorily on this medium were selected for study. Cells were harvested by centrifugation and washed three times with water. The washed cells were suspended in a small volume of water, lyophilized, and ...
متن کاملBiodegradation: Involved Microorganisms and Genetically Engineered Microorganisms
Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds [1]. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms [2]. When biodegradation is complete, the process is called "mineralization". However, in most cases the term biodegra‐ dation is generally used to describ...
متن کاملPrinciples and Methods of Microencapsulation of Probiotic Microorganisms
Worldwide popularity of probiotic- microorganisms and their products on the one hand, and their general weak viability in food products (especially fermented types) as well as gastrointestinal conditions on the other hand, has encouraged researchers to innovate different methods of probiotics viability improvement. Microencapsulation of the probiotic cells is one of the newest and highly effic...
متن کاملSubgingival Distribution of Microorganisms
Composition of subgingival microbiotas has long been seen as being of primary importance in the etiology of periodontal diseases. Development of advanced molecular methods has improved our knowledge about the role of traditional periodontal pathogens as well as resulted in the recovery of novel pathogen candidates. Detection rates of these microorganisms vary considerably between geographical r...
متن کاملMetachromatic Granules of Microorganisms'
The exact nature and function of the metachromatic (volutin) granules seen in many microorganisms is still a matter of conjecture although polymetaphosphates (polymers of highenergy anhydride-linked phosphates) are a known constituent. The object of this paper is to re-examine volutin as a cytological entity, and to present a working hypothesis on the mechanism of formation of this substance. T...
