Embodiment 1

[0028] Example 1 Configuration of Bacteria Solution

[0029] The biological bacteria used in the present invention have been preserved on April 6, 2012 at the General Microorganism Center (CGMCC, No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing) of the China Microbiological Culture Collection Management Committee, and the preservation number is CGMCC. Acinetobacter lwoffii No.5973, Pseudomonas fluorescens No.5974, Wickerhamomyces anomalus No.5975.

[0030] The above-mentioned composite bacteria group is configured into a composite bacteria aqueous solution according to the following mass ratio, which is the bacterial solution:

[0031] Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1-2:1-2:2-3; the density of the formed bacterial liquid is more than 60 million bacteria / ml, for later use.

Embodiment 2

[0032] Example 2 Preparation of fibers from woody raw materials

[0033] Using caragana as raw material, the cellulose preparation method when woody raw materials are used is described in detail. The other woody raw materials, such as the cellulose preparation method of poplar and willow, can be carried out with reference to this process. When caragana is used, the composite flora is configured according to the following mass ratio: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 2:2:2; when poplar is used, the composite flora is configured according to the following mass ratio Configuration: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 2:1:2:2:3; when using willow, the composite flora is configured according to the following mass ratio: Acinetobacter ruckeri: Pseudomonas fluorescens Monocellular bacteria: Wickerhamomyces anomalus is 1:2:2.

Embodiment 3

[0054] Example 3 Preparation of cellulose from herbal raw materials

[0055] Using wheat straw as a raw material, the cellulose preparation method when the herbal raw material is used is explained in detail. The other herbal raw materials, such as the cellulose preparation method of straw and reed, can be carried out with reference to this process.

[0056] When wheat straw is used, the composite flora is configured according to the following mass ratio: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1:2:2; when straw is used, the composite flora is configured according to the following mass ratio Configuration: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 2:2:2; when reed is used, the composite flora is configured according to the following mass ratio: Acinetobacter ruckeri: Pseudomonas fluorescens: Wickerhamomyces anomalus is 1:3:2.

Abstract

The invention relates to mixed bacteria and use thereof in cellulose used for preparing additives. The mixed bacteria comprise acinetobacter lwoffii with a collection number of CGMCC No.5973, pseudomonas fluorescens with a collection number of CGMCC No.5974, and wickerhamomyces anomalus with a collection number of CGMCC No.5975. A process for preparing the cellulose used for preparing additives comprises the following steps of: preparing a bacterial solution; processing raw materials; preparing fibers by defibering, biodegradation, steam sterilization and fiber collection; and sterilizing, and grinding. The method is environment-friendly, because waste liquid is changed into organic fertilizers directly rather than being discharged. In the biological treatment process, the fibers are protected. Compared with the conventional chemical methods, the process has the advantages that the production cost is low, the economic benefit is high, energy can be saved and pollution is avoided.

Description

technical field [0001] The invention relates to cellulose for additives, in particular to a composite bacterial flora and its application in preparing cellulose for additives. Background technique [0002] Cellulose is a polysaccharide compound and is the most valuable natural renewable resource for human beings. Cellulose chemistry and industry began more than 160 years ago, and it was the main research object during the birth and development of polymer chemistry. The main physiological functions of cellulose are to absorb a large amount of water, increase the amount of feces, promote intestinal peristalsis, and accelerate the excretion of feces. The residence time of substances in the intestinal tract is shortened, and the adverse stimulation to the intestinal tract is reduced, thereby preventing the occurrence of intestinal cancer. In the prior art, the preparation of cellulose is mostly through chemical methods, and the waste liquid generated in the production of chemic...
