Aerobic biodegradation of 4-methylquinoline by a soil bacterium
Article Abstract:
Both the isolate Lep1 and the consortium containing Lep1 of a gram-negative bacterium strain metabolize 4-methylquinoline under aerobic conditions. The two proposed metabolites in the degradation pathway are 2-hydroxy-4-methylquinoline and hydroxy-4-methylcoumarin. Lep1 has a narrow substrate range and is unable to degrade N-heterocyclic aromatic compounds or polyaromatic hydrocarbons. Lep1 utilizes several simple carbon sources only in the presence of growth factors but grows quite well on alanine and aspartate without additional carbon or nitrogen source.

Characterization of Thiobacillus thioparus LV43 and its distribution in a chemoautotrophically based groundwater ecosystem
Article Abstract:
The characteristics of Thiobacillus thioparus strain LV43 obtained from Movile Cave is studied. The cave is the entrance to a groundwater ecosystem in southern Romania and is the habitat of terrestrial and aquatic animals. LV43 is a gram-negative bacteria that thrives autotrophically on the oxidation of thiosulfate and sulfide. The study is part of a another study designed to find out the microbial food base and other chemoautotrophic sulfur oxidizers in the ecosystem.

Mycobacterium diversity and pyrene mineralization in petroleum-contaminated soils
Article Abstract:
Mycobacterium strains are less diverse in soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAH) than in soil that is less contaminated. This bacterium competes with indigenous microorganisms in the soil, which would affect PAH biodegradation.
