THE VALUE OF HETEROGENEITY OF BACTERIA POPULATION, CREATED BY THE PROCESS OF DISSOCIATION, FOR THE GROWTH OF PURPLE PHOTOSYNTHETIC BACTERIA IN THEIR NATURAL HABITAT

Abstract

For the first time R- and M-dissociants were isolated from the population of purple phototrophic bacterium Rhodobacter capsulatus, their growth under different luminance and aeration conditions was studied. Earlier, similar experiments were conducted with R- and M-dissociants of Rhodobacter sphaeroides. The physiological-biochemical differences of connatural bacterial species correlate with the distinctions of their inhabitation: Rhb.spheroides isolated from the soil is characterized by low speed of growth along with the ability to grow in dark and aerobiotic places demonstrated only by M-dissociant, which offers this specie an advantage in adaptation for limited and heterogeneity space. Being extracted from the water, rapidly growing Rhb. capsulatus is better adapted for habitation at a free space.
