Bacillus amyloliquefaciens and application thereof

Abstract

The invention discloses a bacillus amyloliquefaciens and an application thereof. The bacillus amyloliquefaciens with the China general microbiological culture collection number 4516 (China general microbiological culture collection (CGMCC) NO: 4516) has an obvious inhibiting effect on the growth of algae, especially has a high-efficiency inhibiting effect on the growth of anabaena flos-aquae, and can be applied to algal bloom control or algal removal of water environments such as lakes, urban landscape water and the like which are in eutrophication state.

Description

technical field [0001] The invention relates to a bacterium, in particular to an algae-dissolving bacterium with high-efficiency algae-inhibiting effect. Background technique [0002] In the case of increasingly serious water eutrophication, economical, convenient and environmentally friendly biological methods ( et al., 1998; Carpenter et al., 1992) has become a research hotspot in the field of eutrophic water restoration. The research on algae control by algae-dissolving bacteria has been carried out gradually since the 1960s, and has been paid more and more attention. Domestic and foreign researchers have studied marine red tides (Imai et al.; 2001), eutrophic lakes (Rashidan et al.; 2001), reservoirs (S.W.Jung et al.; 2008), farmland drainage channels (Jeffrey; 1981), sewage (James et al.; 1969) , lake sediment (Choi Hee-jin et al.; 2005) and other environments isolated algicidal bacteria with anti-algae effect. [0003] Bacillus amyloliquefaciens is a non-pathogenic...

AI Technical Summary

Problems solved by technology

At present, domestic research on it is limited to the optimization of fermentation conditions, the degradation of the herbicide butachlor (Tan Wenjie et al.; 2005), and the inhibition of plant pathogenic fungi and viruses (Shen Lili et al.; 2010) in biological control (Wang Yingying et al.; 2007 ), the research in the field of algae control is still blank
