Abstract

The present invention relates to a kind of colloidal bacillus bacterial strain, classification name is colloidal bacillus (Bacillus mucilaginosus), has been preserved on November 15, 2013 in the general microbiology center of China Committee for Microorganism Culture Preservation, and the preservation number is CGMCC No. 8478. The invention also relates to the application of the colloid bacillus in the degradation of seaweed. The colloid bacillus strain of the present invention has strong seaweed degradation ability, and the content of alginic acid in the degradation solution obtained by using the strain to degrade seaweed is ≥15g / l, which is significantly improved compared with the existing biodegradation technology. In addition, the strain also has the ability to strongly degrade cellulose, protein and alginate. The enzyme activity of cellulose in the fermentation broth is ≥48.5U / ml, the activity of protease is ≥4.5U / ml, and the activity of lyase of alginate is ≥0.855U / ml.

Description

technical field [0001] The invention relates to a colloid bacillus strain and its application in seaweed degradation, belonging to the field of biotechnology (microorganism). Background technique [0002] Seaweed (Alga) is algae that grows in the sea and is a cryptogamous plant in the plant kingdom. They are generally considered to be simple plants, and the main features are: no vascular tissue, no real differentiation of roots, stems, and leaves; no flowering, no fruits and seeds; no specialized protective tissues for reproductive organs, often directly formed by a single Cells producing spores or gametes; and no embryo formation. Seaweed is a lower plant with a wide variety. According to the different pigments contained in seaweed, it can be divided into green algae (such as Ulva), brown algae (such as kelp, sargasso, seaweed, macroalgae, etc.), Bacillus), golden algae (such as Calcifera), etc. [0003] In addition to a large amount of non-nitrogen-containing organic m...
