摘要
[目的]分析稻田固氮蓝藻挥发性成分,评估其应用潜力。[方法]采用气相色谱-质谱联用(GC-MS)分析方法对5株稻田固氮蓝藻的挥发性化学成分进行分析与鉴定。[结果]固氮蓝藻挥发性成分中有多种生物活性功能的烷烃、酚类和酯类物质,具有抗动植物病原微生物、抑制有害藻类、抗草、杀虫等作用。[结论]稻田固氮蓝藻在生物源药物、杀藻剂和农药等生产领域具有应用价值。
[Objective] The aim was to analyze volatiles of several nitrogen-fixing cyanobacteria isolated from rice fields to evaluate its potential applications. [Method]The volatile compounds of five nitrogen-fixing cyanobacteria were isolated and identified by using gas chromatography-mass spectrometry. [Result]Some alkane,phenols and esters appeared in algae with some biological activities in inhibiting or killing animal and plant pathogenic microorganisms,harmful algae,weeds,insects,etc.. [Conclusion]It illustrates that nitrogen-fixing cyanobacteria isolated from rice-field can be used as biological source drug,pesticide and algicide.
