    Industrial waste contains a significant amount of valuable components that can be extracted biotechnologically with the help of microorganisms. To do this, it is necessary to establish the population structure of waste microflora and isolate the active strains of microorganisms that are promising for further use for biohydrometallurgical purposes. The purpose of this work was to determine the composition and structure of the microbial population and isolate the active strains of microorganisms occurring in e phosphoruscontaining waste and polymetallic ores in southern Kazakhstan. It has been shown that the structure of the microbial population of phosphorus-containing and polymetallic waste in southern Kazakhstan is represented by micromycetes in 50.4±5.2% and 38.9±3.4%, bacteria 40.8±4.0% and 53.4 % 5.8%, actinomycetes 8.8±4.0% and 7.7±0.7%, respectively. It has been found that the microorganisms are the most abundant at the depth of 10-30 cm, which is explained by optimal conditions: gas-air regime, humidity, lack of insolation. Active strains were selected from 225 isolates of microorganisms isolated from two types of waste and classified, according to molecular genetic analysis as the following micromycete species: Aspergillus terreus IOM, A. flavus AsF, A. flavus AsZ, A. niger AsIA, A. toleingensis ASPN, bacteria: Sulfobacillus thermosulfidooxydans ST; Gallionella capsiferriformans TS, Pseudomonas stutzeri NJA, Methyloversatilis thermotolerans MSO, Ralstonia рickettii ASA, R. рickettii TS2, Zoogloea resiniphila NS1, Nitrosomonas europeae Nit1, Acinetobacter sp. NAO, Acidithiobacillus ferrooxidans ThIO1, A. ferrooxidans ThIO2. The species Ralstonia рickettii identified in the ore microflora of southern Kazakhstan waste has been described for the first time from this location.
