Amino acid assimilation by representatives of the Acholeplasma genus

: Amino acid assimilation by different representatives of Acholeplasma genus has been investigated. It was shown that all 7 investigated typical strains Acholeplasma laidlawii PG-8, A. granularum BTS-39, A. modicum PG-49, A. oculi 19-L, A. morum 72-043, A. axanthum S-743, A. hippikon C-1 and 37 phytopathogenic strains isolated from the affected plants were able to assimilate asparagine, glutamine, threonine, histidine and proline. A majority of acholeplasmas were able to metabolize phenylalanine, methionine, glutamate and lysine, rarely isoleucine. Each of the investigated species of acholeplasmas had individual spectrum of assimilated amino acids that can be used as an additional systematic characteristic of mollicutes.
