Methanosarcina is a genus of euryarchaeote archaea that produce methane. These single-celled organisms are known as anaerobic methanogens that produce methane using all three metabolic pathways for methanogenesis.

Methane-producing composite microbial inoculum and preparation method thereof

InactiveCN101705199AReasonable designBreed fastBacteriaMicroorganism based processesBiogas productionLiquid methane

The invention relates to a methane-producing composite microbial inoculum and a preparation method thereof, which can solve the long-standing difficult problems that the existing biogas digester is lack of high-efficient methane-producing bacteria, thereby resulting in long initial start-up time of biogas production and poor stability of the biogas production. Methanosarcina acetoacidophilum DSM-N0.2834, methanobacterium formicicum DSM-No.1535, methanobrevibacter arboriphilicus DSM-No.1125, methanolobus tindarius DSM-No.2278 and methanothrix concilii DSM-No.6752 collected in German collection of microorganisms and cell cultures are adopted and inoculated in a liquid methane bacterial culture medium under the anaerobic condition, the independent enlarged culture is carried out grade by grade respectively, and bacterial liquid after the cultured methane bacteria is mixed together according to the volume ratio, thereby preparing a liquid methane-producing composite microbial inoculum; and the liquid methane-producing composite microbial inoculum can also be prepared into a solid methane-producing composite microbial inoculum. The method has reasonable design and adopts the high-efficient strains with the optimal combination and the rapid propagation technology, and the developed high-efficient methane-producing composite microbial inoculum can significantly accelerate the start-up time of the biogas production when in new construction of the biogas digester and large material change, and improve the efficiency and the stability of the biogas production of the biogas digester.

Fast culture process in anaerobic grain sludge

InactiveCN1887737AReduce startup timePromote growthBacteriaWaste based fuelGenus MethanosarcinaMicroorganism

The fast culture process of anaerobic granular sludge belongs to the field of bitanical waste water treating technology, and features that polyquaternary ammonium salt is thrown to reinforce the immobilization of anaerobes to form granular sludge fast. Throwing polyquaternary ammonium salt can reserve methane sarcina to speed the accumulation of methane sarcina, raise the methane producing activity of biological grain and shorten the granulating process. The present invention makes it possible to shorten the starting time of anaerobic reactor to 1-3 months. The polyquaternary ammonium salt as flocculant hard to biodegrade may be absorbed by microbes to form granular sludge with high active component content. The positively charged polyquaternary ammonium salt may be absorbed and adsorbed by negatively charged bacteria to create great amount of biological aggregate capable of strengthening the biological floc, so as to form compact granular sludge with excellent depositing performance.

ActiveCN109439572AEasy to breedEasy to handleFungiBacteriaBacillus licheniformisTreatment effect

The invention discloses a microbial agent for sewage treatment. The microbial agent comprises, by weight, 8-10 parts of clostridium acetobutylicum, 12-16 parts of bacillus licheniformis, 16-20 parts of bacillus subtilis, 5-7 parts of lactobacillus acidophilus, 5-7 parts of methanosarcina, 3-5 parts of methanosaeta, 6-8 parts of rhodopseudomonas palustris, 4-6 parts of cellulomonas flavigena, 8-10parts of streptococcus thermophilus, 8-10 parts of alcaligenes faecalis, 3-5 parts of bacillus amyloliquefaciens, 2-4 parts of bacillus nitrosomonas, 1-3 parts of issatchenkia orientalis and 3-5 partsof streptomyces bullis. Besides, the invention further discloses an attachment carrier of the microbial agent and a preparation method of the microbial agent. The microbial agent can be effectively attached to the carrier and accordingly has better activity. The microbial agent is reasonable in strain preparation and can be effectively attached to the attachment carrier to treat sewage, and the method for sewage treatment is simple, good in treatment effect and worthy of popularization.
