Eleven strains of pink-pigmented bacteria, isolated from the leaf surface of Loliumperenne (perennial rye grass), were compared with six marker strains and 50 pink-pigmented isolates from a variety of habitats. The organisms were examined for 146 unit characters, and the data were analyzed by the simple matching and Jaccard coefficients and the average-linkage algorithm. The Lolium strains form...

Plant growth-promoting bacteria (PGPB) have great potential to provide economical and sustainable solutions current agricultural challenges. The Methylobacteria which are frequently present in the phyllosphere can promote plant growth development. Methylobacterium genus is composed mostly of pink-pigmented facultative methylotrophic bacteria, utilizing organic one-carbon compounds as sole carbo...

Actinomycetes play an important role in the decomposition of various organic materials and replenish the supply of nutrients in the soil. They also produce many secondary metabolites possessing antimicrobial properties. The present study was conducted to determine the antibacterial and enzyme producing capabilities of soil Actinomycetes isolated from Nahargarh hill area, Jaipur, Rajasthan, Indi...

Periodontal diseases are inflammatory responses thought to be triggered by specific microorganisms colonizing in the gingival crevice. Theoretically, periodontal diseases could be prevented if the etiologic organisms were not allowed to colonize the subgingival area. The humoral immune response is one mechanism which may modulate bacterial colonization in the gingival crevice. To test the effec...

The morphological and physiological characteristics of 20 strains of motile, gram-negative, yellow-pigmented oxidative bacilli (groups VE-1 and VE-2) isolated in clinical bacteriology are described. Electron micrographs demonstrate the polar multitrichous flagella of group VE-1 and polar monotrichous flagella of group VE-2. Data obtained from guanine plus cytosine ratio studies of 56.8% for VE...

The plasmid pC5, which encodes biogenesis of lycopene in Mycobacterium aurum A(+), was partially digested by restriction endonucleases and generated fragments were cloned. After transformation of Escherichia coli (colorless bacteria) with the plasmids so constructed, seven orange clones were detected and found to carry the same recombinant plasmid (pC51). E. coli cells containing this plasmid s...
