Structural changes induced by glycine on Streptomyces antibioticus
Germination and vegetative growth of Streptomyces antibioticus in liquid medium with different concentrations of glycine was examined. Both processes proved to be sensitive to the amino acid, being inhibited by 5 and 2.5% glycine, respectively. At concentrations of 5% or more, lysis of the vegetativ...

| description | Germination and vegetative growth of Streptomyces antibioticus in liquid medium with different concentrations of glycine was examined. Both processes proved to be sensitive to the amino acid, being inhibited by 5 and 2.5% glycine, respectively. At concentrations of 5% or more, lysis of the vegetative mycelium occurred. Subinhibitory concentrations of glycine induced structural changes on germinating spores. These included an increase in the number of germ tubes produced by spore, in relation to the control. Moreover, soon after outgrowth the tubes bifurcate, giving rise to germinated spores with a characteristic aspect, and anomalous formation of cross‐walls that appear both within the spores and in the newly formed germinative tubes, at or close to the region of outgrowth. The branching effect of glycine was also observed during vegetative growth of S. antibioticus. |
