Abstract

Amino acid assimilation by different representatives of Mycoplasma genus has been investigated. All typical strains, involved in this research--Mycoplasma pneumoniae, M. capricolum, M. hominis, M. mycoides subsp. capri, M. fermentans, M. salivarium were able to assimilate asparagine, glutamine, threonine, histidine and tryptophan. Most of the investigated mycoplasmas were able to assimilate proline, phenylalanine, methionine, glutamate, lysine, serine, tyrosine, glycine, valine, isoleucine and alanine; assimilation of leucine and cysteine was observed rarely. Each of the investigated species of mycoplasmas are characterized by a specific spectrum of assimilated amino acids that can be used as additional characteristic for systematics of mollicutes.

摘要

对支原体属不同代表菌株的氨基酸同化作用进行了研究。参与本研究的所有典型菌株——肺炎支原体、山羊支原体、人型支原体、丝状支原体山羊亚种、发酵支原体、唾液支原体都能够同化天冬酰胺、谷氨酰胺、苏氨酸、组氨酸和色氨酸。大多数被研究的支原体能够同化脯氨酸、苯丙氨酸、甲硫氨酸、谷氨酸、赖氨酸、丝氨酸、酪氨酸、甘氨酸、缬氨酸、异亮氨酸和丙氨酸；很少观察到亮氨酸和半胱氨酸的同化作用。每种被研究的支原体物种都具有特定的同化氨基酸谱，可作为柔膜菌纲系统分类的附加特征。
