Description
Technical field
The present invention relates to a kind of additive Mierocrystalline cellulose, relate in particular to a kind of composite flora and prepare the cellulosic method of additive with it.
Background technology
Mierocrystalline cellulose is compound of polysaccharide, is the most valuable natural reproducible resources of the mankind.Cellulose chemistry and industry started from before more than 160 year, polymer chemistry birth and the main study subject of developing period, cellulosic major physiological effect is absorption large quantity of moisture, increase ight soil amount, promote intestinal peristalsis, accelerate the excretion of ight soil, the residence time of carcinogenic substance in enteron aisle shortened, the pessimal stimulation of enteron aisle is reduced, thus can prevention of intestinal carcinogenesis.In prior art, prepare Mierocrystalline cellulose, how by chemical process, the waste liquor contamination sublimity that chemical process produces in producing, damage to land, polluted air, and also it is high to consume energy, and power consumption and water consumption are large.Do not meet national energy-saving and reduce discharging policy.Material can not reach Efficient Cycle recycling.Chemicals cannot separate from waste liquid, and organism and chemicals mix, and organism also cannot be reused, and causes a large amount of losses.
Therefore, be necessary to develop biological cellulose technology processed, fundamentally solve an above-mentioned pollution difficult problem, energy-saving and emission-reduction, water-saving, reduces production costs and improves the rate of utilization of material.
Summary of the invention
The object of the invention is to overcome the cellulosic above-mentioned defect of chemical legal system of prior art, a kind of new Mierocrystalline cellulose biological bacteria of preparing is provided.Contriver, by long screening operation, has obtained and has been suitable for preparing the cellulosic biological bacteria that can realize foregoing invention object.
Particularly, the invention provides a kind of composite flora, it comprises the silent Salmonella (Rheinheimera tangshanensis) of Tangshan Lay mattress that preserving number is CGMCC No.5972, preserving number is the acinetobacter lwoffii (Acinetobacter lwoffii) of CGMCC No.5973, preserving number is the Pseudomonas fluorescens (Pseudomonas fluoscens) of CGMCC No.5974, preserving number be this Wickerhamomyces anomalus bacterium of Wickerhamomyces anomalus(of CGMCC No.5975 in malt juice liquid medium 25 ℃ cultivate three days, cell is spherical, avette, sausage shape, size is (4.8-14.4) × (3.6-7.2) μ m, there is precipitation to form.25 ℃, wort agar inclined-plane cultivation one month, bacterium colony cheese shape, oyster white, surface smoothing, not reflective, edge root shape.Corn Meal Agar Dalmau is dull and stereotyped to be cultivated, and produces pseudohypha).
Described composite flora can be used in prepares additive Mierocrystalline cellulose.
The present invention also provides one to prepare the cellulosic method of additive, and it mainly comprises step:
1) configuration of bacterium liquid: above-mentioned composite flora is configured to the composite bacteria aqueous solution according to following mass ratio, is bacterium liquid:
The Tangshan Lay mattress Salmonella of writing from memory: acinetobacter lwoffii: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1-2:1-2:1-2:2-3;
2) raw material processing: by section after woody raw material peeling, or draft raw material is cut into chunks, the raw material cutting is put into fermentation vat swollen;
