Chemotaxis of rhizoplane bacteria to amino acids comprising eelgrass (Zostera marina L.) root exudate

Chemotaxis of rhizoplane bacteria to amino acids comprising eelgrass (Zostera marina L.) root exudate

Journal of Experimental Marine Biology and Ecology 50(2-3): 153-162

Scanning electron microscopy showed a large bacterial population on Z. marina L. roots. The 5 dominant motile rhizoplane bacteria isolated were chemotactically attracted to Z. marina root exudate. Dansylation and TLC analysis of root exudate identified the presence of serine, threonine, glycine, alanine and valine. When gentamicin sulfate was added during exudate collection, serine and threonine were not detected. Exudate amino acids were shown to chemotactically attract motile rhizoplane isolates.
