Bacteria L-4 of South China Sea[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2013,52(3):77-82.DOI:
The influence of secondary metabolites on the mix-cultivate marine bacteria and fungus were studied.The result indicated that bacteria obviously affected the secondary metabolites of fungus in the mix-cultivate
and even produce substances that were not found in the fungus or bacteria separately culture by TLC. Eight compounds were obtained from the fermentation broth of coral-derived bacteria L-4 in South China Sea. Their structures were determined to be cyclo (TrpAla)
(1)
cyclo (GlyTyr)(

cyclo (AlaTyr) (

and cyclo (ValTyr)(

cyclo (GlyPhe)(

and cyclo (GlyAla)(

) by spectroscopic analysis. The compounds

were all cyclo-dipeptides and first obtained from the marine coral-derived bacterium of South China Sea
which attributed to further research metabolism of mix-cultivation.
