- Formation of trans fatty acids is not involved in growth-linked membrane adaptation of Pseudomonas putidaClaus Härtig
Department of Environmental Microbiology, UFZ Centre for Environmental Research Leipzig Halle, P O Box 500136, 04301 Leipzig, Germany
Appl Environ Microbiol 71:1915-22. 2005..The cis-trans isomerization reaction was in competition with the cis-to-cyclopropane fatty acid conversion. The potential for the formation of trans fatty acids depended on the cyclopropane content that was already present...
