In this paper, we describe research into the biochemical processes of brown coal treatment. s. The modified biochemical model was formed from a complex biological treatment of low-rank coals with an added cycle of aerobic conversion and the process of converting a sulphur compound under anaerobic conditions, as well as a number of ecological-trophic groups of microorganisms.

Perhaps even more interesting than the number of giraffes is their coexistence with people and livestock in the "tiger bush". Giraffe here are in permanent contact with people, their crops and livestock.
