    Effect of solid particles on the growth and endurance to heat stress of garbage compost microorganisms (1978)

    Notes: Summary A mixed population of microorganisms isolated from the municipal garbage compost was cultivated in a full nutrient liquid medium under aerobic conditions. In order to simulate the presence in compost of both noncolloidal and colloidal solid particles, glass beads, bentonite, or humic acid were added to the cultures. The growth of microorganisms and the CO2 evolution rose with bentonite and humic acid, but the humic acid did not enhance the growth of the potential pathogenic bacteria. Solid particles appreciably influenced the endurance to heat stress of microorganisms supporting their adaptation to the changed temperature.

    Decomposition of polyurethane in a garbage landfill leakage water and by soil microorganisms (1978)
    Springer
    Applied microbiology and biotechnology 5 (1978), S. 225-231

    Notes: Summary The decomposition of polyurethane, measured gravimetrially or using infrared spectrophotometry, was found to be more complete in polyurethane based on polyester and only very small in polyurethane based on polyether. In the presence of clay minerals the decomposition was inhibited. If positive, the decomposition of polyurethane followed the sequence: remaining free isocyanates→urea and amide groups→urethane groups→isocyanuric acid rings.
