Volatiles Analysis of Several Nitrogen-fixing Cyanobacteria Isolated from Rice Fields Using Gas Chromatography-mass Spectrometry |
| |
| Abstract: | 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. |
