Modeling of Possible Processes for Origin of Life and Living Matter in Hot Mineral Water. Research of Physiological Processes of Bacterium Bacillus Subtilis in Hot Heavy Water

Ignat Ignatov, Oleg Mosin


The physiological influence of deuterium on the Gram-positive chemoheterotrophic bacterium Bacillus subtilis, producer of inosine was studied on a heavy water (HW) medium with a maximal concentration of 2H2O. With the use of IR-spectroscopy (DNES-method) were studied samples of hot mineral water and sea water derived from different sources of Bulgaria. There are presented the data on the growth and the adaptation of B. subtilis in highly deuterated growth media with 2% (w/w) hydrolysate of deuterated biomass of the methylotrophic bacterium Brevibacterium methylicum as a source of 2H-labeled growth substrates. It was studied the qualitative and quantitative composition of the cellular protein, amino acids and carbohydrates in the conditions of cellular adaptation to 2H2O. The taxonomy of the studied bacterium and the ability for assimilation of carbon substrates was also analyzed on an evolutionary level. It was shown on the example of chemoheterotrophic bacteria that hot mineral water with pH = 911 is more suitable for maintenance and origin of life than other water samples.
