title: Fatty acids present in the lipopolysaccharide of Rhizobium trifolii.
abstract: Approximately 70% of the fatty acids recovered after acid or alkaline hydrolysis of the lipopolysaccharide of Rhizobium trifolii were hydroxy fatty acids identified as hydroxymyristic and hydroxypalmitic acids. Palmitic acid was the only saturated fatty acid found in the lipopolysaccharide of R. trifolii. Octadecenoic and a small amount of hexadecenoic acids were also identified. The results of BF(3) methanolysis and hydroxylaminolysis suggest that hydroxypalmitic acid is N-acyl bound.
