Isolation and identification of nitrogen fixing bacteria associated with Kappaphycus alvarezii
The commercially important red algae, Kappaphycus alvarezii grow well in nutrient limited water. The present study aimed to isolate bacteria, particularly nitrogen-fixing bacteria associated with algae, using designated media and characterize them by amplifying the nifH and 16S rRNA genes. These nitrogen-fixing bacteria could be applied in seaweed cultivation, which is an emerging focus area with considerable economic benefits for coastal communities.
