Rationale Biological organisms for the prevention of turfgrass diseases are now available and in widespread use. Biological control is achieved through antagonistic action of one organism toward another such as a pathogen or weed. At present, no genetically engineered organisms are available in the turfgrass industry, however, as advances in biotechnology increase the activity of wild type (nat...

Purpose: As a newly cultivated grass species widely used in saline-alkali soil treatment, Juncao"Oasis No.1" can effectively enhance the microbial population abundance soil. It has good effect on improving Methods: In order to further study community rhizosphere of No.1”, dominant strains with important ecological value were screened out. this paper, samples collected from planted No. 1" and un...

In order to screen the strains with Potassium and phosphorus-releasing bacteria from soil, potassium-dissolving medium was used for preliminary screening, transparent circle method re-screening. The content of soluble potassium determined by sodium tetraphenylborate method, phosphorus anticolorimetric molybdenum antimony. were identified morphological, biochemical molecular biology. results sho...

Using immunomagnetic separation with beads coated with polyclonal anti-treponemal antisera and prolonged anaerobic broth culture a novel spirochaete was isolated from a case of severe virulent ovine foot rot (SVOFR). The as yet un-named treponeme differs considerably on morphology, enzymic profile, and 16SrDNA sequence from the only other spirochaete isolated from ovine foot rot. On the basis o...

16SrDNA-targeted genus- and species-specific PCR primers have been developed and used for the identification and detection of bifidobacteria. These primers cover all of the described species that inhabit the human gut, or occur in dairy products. Identification of cultured bifidobacteria using PCR primer pairs is rapid and accurate, being based on nucleic acid sequences. Detection of bifidobact...
