Impact of the microscale distribution of a Pseudomonas strain introduced into soil on potential contacts in indigenous bacteria

Article Abstract:

The microscale spatial distribution of a gfp-tagged derivative of Pseudomonas putida KT2440 introduced into soil columns by percolation is characterized. The results indicate that the microscale spatial distribution of an introduced strain strongly limit its contacts with the members of an indigenous bacterial community, which explains about the low number of indigenous transconjugants found most of time when a plasmid-donor strain is introduced into soil.

Analysis of the life cycle of the soil saprophyte Bacillus cereus in liquid soil extract and in soil

Article Abstract:

A program is initiated for investigating the behavior of the soil bacterium Bacillus cereus when it occurs in liquid soil extract and in soil. Determination of whether Bacillus cereus is able to grow and perform a full life cycle in liquid soil extract and in artificial soil microcosms indicates that Bacillus cereus ATCC 14579 and related soil isolates reveal a complete saprophytic life cycle in conditions mimicking the soil environment.

Role of autochthonous filamentous fungi in bioremediation of a soil historically contaminated with aromatic hydrocarbons

Article Abstract:

A study was conducted on the role of autochthonous filamentous fungi isolated from an aged and heavily contaminated soil with aromatic hydrocarbons in assessing their degradative potential. It was observed that there was a significant decrease in soil toxicity due to the presence of autochthonous fungi.
