Abstract: Microbial growth and division are fundamental processes relevant to many areas of life science, of particular interest are homeostasis mechanisms, which buffer growth and division from accumulating fluctuations over multiple cycles. These mechanisms operate within single cells, possibly extending over several division cycles. Experimental studies to date have relied on measurements pooled from many distinct cells. The microbial population analysis was carried out through microbial plate count. By analyzing correlations along up to hundreds of generations, we find that the parameter describing effective cell size homeostasis strength varies significantly among cells. The mixed cultured of Bacillus licheniformis and Alcaligenes eutrophus bacterial were capable of growing at a rate such that the culture doubles in biomass every 2.302 days in Benzene, 2.180 days in Xylene and 2.032 days in Ethylene substrate. Bacillus licheniformis was capable of growing at a rate such that the culture doubles in biomass every 2.3255 days in Benzene and Ethylene while 2.207 days in Xylene. Alcaligenes eutrophus was capable of growing at a rate such that the culture doubles every 2.7305 days in Benzene, 2.398days in xylene and 2.3623 days in ethylene substrate. There was higher competition between consortium of two species than single species of the bacterial organism, the consortium of two species will also enhance the degradation of benzene in aromatic compounds contaminated soil. The Bacillus licheniformis and Alcaligenes eutrophus bacteria can be use for bioremediation of aromatic compounds contaminated soil such as benzene and xylene.
