Occurrence of phosphatidylcholine in hydrogen-oxidizing bacteria.
15 strains of hydrogen-oxidizing bacteria were grown heterotrophically, harvested during the stationary phase of growth, and analyzed for their principal phospholipids. All strains - with the exception of Corynebacterium autotrophicum strain SA 32 and Pseudomonas pseudoflava - contained phosphatidylcholine as a major constituent. It is concluded that the presence of phosphatidylcholine is neither characteristic of a peculiar bacterial genus or family, nor is it absolutely correlated to the ability to oxidize hydrogen. The phosphatidylcholines of all strains contain C19 cyclopropane acid which is, in some strains, predominantly located at C-2 position of the glycerol moiety.
