Study of the microbiological composition of sludge during the cultivation of Chironomus larvae

Silt (nutrition medium) is the habitat of many microorganisms that adapt well to water and soil. By extended aeration, it partially comes out sewage. The nature organic impurities determines composition such a substrate, so its leading indicators may vary. Such nutrient medium one favorable conditions for growth development Chironomus larvae various microflora. article presents results studies bacteriological crops substrate establish microbiological under pasteurization modes. It was found in native sludge, colony bacteria family Pseudomonas spesialis 80 %, Bacillus subtilis 15 Micrococcus luteus 5 % total number colony-forming organisms. also different modes lead decrease medium. When pasteurized at 65 °C (long-term), decreased by 16 times. 75 (short-term), organisms 22 times, 95 (instant), 358 times compared with form
