ABSTRACT
This chapter is devoted to the obtaining and study of biosorbents based on carbonized carriers: rice husk and apricot stones and immobilized microbial cells Rhodotorula glutinis var and bacterial cells Pseudomonas aeruginosa, Pseudomonas mendocina. The specific surface area of biosorbents based on carbonized materials and microorganism cells was determined. The studies were carried out using physicochemical and biochemical methods: examination of physicochemical characteristics of carbonized sorbents by electron microscopy, atomic absorption spectroscopy, and elemental analysis; specific surface area measurement; determination of the sorption characteristics of carbonized sorbents with regard to heavy metal ions and microbial cells; assessment of sorption activity of the prepared biosorbents with regard to heavy metal ions; determination of viability of attached microbial cells by microcultural analysis, as well as hydrophobic properties of the microbial cell surface. In the literature data, the chemical sorption of microbial cells onto the carriers is explained by the formation of polypeptide bond between two amino acids.
