Abstract
The invention discloses microbial flocculant proteus vulgaris and an application thereof in cane juice clarification. A producing bacterium of a microbial flocculant is proteus vulgaris N-25 which has a collection number of CCTCC (China Center for Type Culture Collection) NO:M2014549 and is collected in the CCTCC on November 5, 2014. The application comprises the following steps: adding phosphoric acid into a cane mixed juice, adjusting the pH value to 6-8 by using lime milk, then heating to 50-70 DEG C, and preserving the heat; and adding sulfurous acid until the sulfur fumigation amount is 1.5-2.0g/L, adjusting the pH value to 7-9, then heating to 60-100 DEG C, adding the microbial flocculant, and standing for 20-40 minutes. The microbial flocculant disclosed by the invention is less in used amount and high in flocculation efficiency, is safe and nontoxic, is easy to degrade biologically, is applied to the sugar industry, and can be used for producing healthier and more environment-friendly products.
