Individually and Synergistic Degradation of Hydrocarbons by Biosurfactant Producing Bacteria

Background: Increasing worldwide contamination with hydrocarbons has urged environmental remediation using biological agents such as bacteria. Our goal here was to study the phylogenetic relationship of two crude oil degrader bacteria and investigation of their ability to degrade hydrocarbons. Materials and Methods: Phylogenetic relationship of isolates was determined using morphological and...

Antibacterial Activities of Extracellular Metabolites of Symbiotic Bacteria, Xenorhabdus and Photorhabdus Isolated from Entomopathogenic Nematodes

Xenorhabdus and Photorhabdus are members of the family Enterobacteriaceae, and are engaged in a mutualistic association with the entomopathogenic nematodes, Steinernema and Heterorhabditis, respectively. In the present study, the organic fraction of ethyl acetate bacterial crude extracts of the symbiotic bacteria, Xenorhabdus stockiae and Photorhabdus luminescens isolated from entomopathogenic ...

Screening and Isolation of Extracellular Protease Producing Bacteria from the Maharloo Salt Lake

      Screening and identification of moderately halophilic protease producing bacteria from different regions of Maharloo, a hypersaline lake in the southern area of Iran, were the objectives of this study. In the preliminary screening, 16 isolates exhibited proteolytic activity on saline skim milk agar. All isolates were able to grow comfortably in the media containing 7-15% of salt. Protease...

Anaerobic benzene degradation by bacteria

Benzene is a widespread and toxic contaminant. The fate of benzene in contaminated aquifers seems to be primarily controlled by the abundance of oxygen: benzene is aerobically degraded at high rates by ubiquitous microorganisms, and the oxygen-dependent pathways for its breakdown were elucidated more than 50 years ago. In contrast, benzene was thought to be persistent under anoxic conditions un...
