英文摘要Fermentative microorganisms present on the surface of seaweed were screened and then identified by 16S rDNA sequence analysis. We obtained the following four fermentative strains: Bacillus megaterium, Leclerciaadecarboxylata, Lysinibacillusmacroides, and Sphingomonasleidyi. Using controlled inoculation proportion of these four strains, we obtained a stable fermentation product. We studiedthe changes and mechanisms of seaweed fermentation processto provide theoretical and data support for industrialization production of seaweed fermentation fertilizer. At 36 h in the fermentation process, alginate oligosaccharides with polymerization degrees of 2-5 were generated and accompanied by secondary growth of fermentative strains and a decreased pH, which were the parameters that could be easily observed and monitored. Fermentation broth diluted 600 times could significantly promote the germination and root growth of wheat seeds. Germination rate was 26% higher and root growth was 37% longer than those in the control group, respectively. These results provided a feasible strategy for the production of seaweed fertilizer by microbial fermentation. This simple and effective fermentation method has strong operability and broad application prospects.
