英文摘要bacteria communicate with each other by a process termed "quorum sensing" (qs), and diffusible, low-molecular-weight chemicals, called signal molecules, are used as the communication languages. in cell-free burkholderia cepacia cf-66 culture supernatants, five compounds suspected of being signal molecules were identified. the gene (cepi) related with ahls synthesis were not detected by polymerase chain reaction (pcr) using specific primers. gas chromatography-mass spectrometry (gc-ms) revealed that these compounds were not ahls but the diketopiperazines (dkps) cyclo(prophe), cyclo(pro-tyr), cyclo(ala-val), cyclo(pro-leu), and cyclo(pro-val), all of which were both d and l-type. four kinds of dkps had been isolated from other gramnegative bacteria, but the other was a novel kind discovered in cf-66, and l-cyclo (pro-phe) was quantified by gc-ms. it was found that exogenous dkps had a negative effect on the candidacidal activity of the culture supernatant extracts.
