DPZ-SYz-36 and the application in the production of cellulose enzyme is degraded bacterial manure with the preparation biological organic matter thereof.
Background technology:
Mangrove forest is the woody plant community, xylium of NATURAL DISTRIBUTION in the torrid zone, seashore tideland, subtropics; Cover about 60～75% torrid zone and subtropics seashores; The eubiosis to safeguarding the river mouth, bay plays an important role, and is important component part (Holguin et al., 2001 of fecundity of the sea; Long Han etc., 2005), be considered to have one of ecosystem than high productivity.This ecosystem has higher organic level (global annual litter is 100Tg C), for the stretch of coastal water and the relevant coenosis habitat of adjoining provides organism (Holguin et al., 2001; Lugomela and Bergman, 2002).Because the mangrove forest settling has strong reducing property, strongly-acid, supersalinity, nutritious (Takeuchi M et al., 1998; Characteristic such as Lin Peng, 1997).Therefore, the mikrobe, enzyme and the genetic resources that have contained a large amount of uniquenesses here.In recent years, mangrove forest unique ecological environment and rich species variety have caused more ocean science workers' concern.But the microbiological research of mangrove area is started late, and research is comparatively weak.At present, the mangrove area microbiological research mainly concentrates on: the research of mangrove forest micro-flora; Microbiological research in the litter decomposition course; The research of mangrove rhizosphere actinomycetes; Mangrove area microbial contamination ecological study (Yuan KP et al., 2005; Muniswaran A.et al.1994).
Along with the shortage of fossil oil, the energy is the significant problem of face of mankind.Seek and develop Sustainable development and even human existence problem that renewable energy source and new forms of energy are related to economy.Mierocrystalline cellulose is different with fossil fuel, and it is a kind of reproducible resource.Annual photosynthesis can produce about 10,000,000,000 tons plant dry matter on the earth, and wherein over half is Mierocrystalline cellulose and semicellulose (Campbell BA et al., 1998).In addition; Also contain a large amount of cellulosic materials in the waste that mankind's activity produces, like agricultural wastes (straw, rice husk, stalk, Pericarppium arachidis hypogaeae, corn cob, cotton seed hulls, bagasse etc.), food-processing waste (pericarp, pomace etc.), timber waste (wood chip, bark) and urban waste (40%～60% solid waste is rubbish and waste paper) etc.If can effectively utilize conversion technology these cellulose resource are changed into simple sugars; Fermentation produces ethanol equal energy source material again; Not only can turn waste into wealth; But also can avoid because fossil energy shortage and even the exhausted worldwide energy dilemma of bringing can alleviated or solve simultaneously to the environmental pollution that combustion of fossil fuel brought.
Because the unique advantage of mikrobe aspect cellulose utilization sought new cellulose utilization bacterial classification and exploitation high yield cellulase strain, is the cellulose resource key for high-efficient use.Can utilize the fungi that eukaryotic microorganisms such as viride (T.virid), black mold (Aspergillus niger) and Trichodermareesei main cellulase-producings such as (Trichogerma reesei) are not only arranged with cellulolytic species; Wherein Trichoderma is to study cellulase producing bacteria the most widely; 20% cellulase is from Trichoderma and Aspergillus in the cellulase market, the world; But in recent years; The research report of new cellulose degradation strain also day by day increases (Mario CNS et al., 2008; Revankar MS et al., 2006).In addition, also have some protozoons and the bacterium also can decomposition of cellulose class material, but because bacterium excretory cellulase amount is few, and the enzyme that produces belong to intracellular enzyme or is adsorbed on the cell walls, so the industrial less production bacterial classification of making cellulase of bacterium.In addition, the animal that has such as termite, small lobsters etc. also can produce and be different from the cellulase that its endosymbiontic microorganism group is produced fully.Because the cellulose degradation fungi has its important effect aspect energy utilization, a lot of for this reason scientific workers have carried out a large amount of research and have obtained significant achievement this type fungi.
