The invention discloses an
obligate halophile fast culture method. A basic culture medium contains MnSO4.7H2O, ZnSO4.7H2O, Na2MoO4, AlK(SO4)2, H2BO4, CaCl2.2H2O and CoCl2.6H2O; an enriching culture medium contains beef extracts, peptone, NaCl, KH2PO4, agaragar and
distilled water, and the pH value is 7.2 to 7.4. The
phosphate buffer solution contains NaCl, KCl, Na2HPO4 and KH2PO4, and the pH valueis 7.2 to 7.4. The
sludge obtained from a secondary
sedimentation tank in a
sewage plant is subjected to aerobic culture in the basic culture medium; the cultured
sludge is subjected to
enrichment culture by the enriching culture medium in a flat plate
coating mode, and is put into a biomedical culture box to be cultured for 72h; the enriching culture medium is taken;
surface layer sludge is scraped and taken; the
phosphate buffer solution is used for repeatedly flushing; then
centrifugation is performed by a high-speed
centrifugation machine; supernatant fluid is removed; bottom layer sludgeis taken; the sludge is high-concentration halophilic sludge. The high-concentration halophilic sludge and the ordinary sludge are taken and proportionally added into a culture medium to be cultured.The method is used for fast culturing
obligate halophile, so that the practical problems of biological treatment of high-salt waste water is solved.
