Ethylene-producing strains of Penicillium cyclopium and P. crustosum were isolated from soil. These isolates produced ethylene on a variety of carbon growth substrates including phenolic acids. The quantities of ethylene produced on the various substrates varied, and the subtrate-ethylene prosuction pattern for P. cyclopium strains differed significantly from that of P. crustosum strains.

INTRODUCTION Contaminated sponges might lead to cross-contamination in kitchens since they can transfer microorganisms to surfaces where microorganisms can survive for hours or days and contaminate food. The main objective of this study was to evaluate the transfer and the survival of bacteria from kitchen sponges to surfaces of AISI 316 stainless steel and polyethylene. METHODOLOGY Twenty-fo...

Demand of all living organisms on the same nutrients forms the basis for interspecific competition between plants and microorganisms in soils. This competition is especially strong in the rhizosphere. To evaluate competitive and mutualistic interactions between plants and microorganisms and to analyse ecological consequences of these interactions, we analysed 424 data pairs from 41 (15)N-labell...

forty bacteria species commonly found in soil, sediments, and sewage effluent were exposed for acclimation to inorganic and organic mercury compounds using sterilized sediments as the culture medium. screening tests for the ability of microorganisms to methylate inorganic mercury were made on all 40 species after acclimation to 13.5 mg/i mercuric chloride. additional screening tests for demethy...

The development of reliable processes for the synthesis of Nanoparticles is an important aspect of nanotechnology. Biologically synthesized nanoparticles could have innumerable applications in different areas such as reception, catalyzers, biolabellers, etc. In the present review, we emphasize the richness of the microbial world which encompasses a plethora of endophytic entities as an emerging...
