  • Marine bacterial strains of cycloclasticus and marinobacter for degradation of high-molecular-weight polycyclic aromatic hydrocarbons
    Patent number: 8652826
    Abstract: A composite marine bacterial liquid for the synergic degradation of high-molecular-weight polycyclic aromatic hydrocarbons (HMW PAHs) and the preparation method thereof. The composite marine bacterial liquid is generated by mixing the fermented culture liquid of a stain of Cycloclasticus sp. PY97M and a stain of Marinobacter sp. D15-8W, the cell concentration of each is 107-109 CFU/mL. The preparation method includes: inoculating the seed liquid of Cycloclasticus strains and Marinobacter strains individually into the sodium acetate medium or M8 medium, fermenting under the condition of defoaming by flowing addition of defoamer, and mixing the fermented cultures to obtain the composite marine bacterial liquid, then preparing a 5-fold concentrated liquid by centrifuging and storing at 4° C.
