英文摘要	in this study, influence of three critical parameters nitrogen sources, initial ph and metal ions was discussed in the production of antifungal lipopeptides from bacillus amyloliquefaciens q-426. the results revealed that lipopeptide biosynthesis might have relations with the population density of strain q-426 and some special amino acids. also, the alkali-resistant strain q-426 could grow well in the presence of fe2+ ions below 0.8 m l(-1) and still maintain the competitive advantage below 0.2 m l(-1). moreover, lipopeptides exhibited significant inhibitory activities against curvularia lunata (walk) boed even at the extreme conditions of temperature, ph and salinity. finally, biosurfactant properties of lipopeptides mixture were evaluated by use with totally six different methods including bacterial adhesion to hydrocarbons assay, lipase activity, hemolytic activity, emulsification activity, oil displacement test and surface tension measurement. the research suggested that b. amyloliquefaciens q-426 may have great potential in agricultural and environmental fields.
