The red-pigmented marine bacterium Pseudoalteromonas sp. sf57 forms a biofilm that deters larval settlement of the tube-building polychaete Hydroides elegans. To investigate the correlation between pigmentation and larval settlement deterrence, mutants of sf57 with deficient or altered pigmentation were generated by transposon mutagenesis. Five groups of(More)
The quorum sensing signals-acyl homoserine lactones (AHLs) were directly detected in 1-9-day-old subtidal biofilms developed in a coastal fish farm by using AHL reporter strains and gas chromatography-mass spectrometry. Both methods showed that the AHL molecules and/or AHL-producing bacterial community were dynamic during biofilm development, with dominant(More)
Earlier studies have shown that biofilms can mediate the larval settlement of the polychaete Hydroides elegans and that changes in the bacterial community structure and density of biofilms often alter the larval settlement response. However, the chemical cues that mediate this response remain unknown. In this study, both successional changes in the(More)
Quorum sensing (QS) signals have been considered to play important roles in biofilm development and in the attractiveness of biofilms to higher organisms in marine ecosystem. In this study, bacterial QS signalsacylated homoserine lactone derivatives (AHLs) were detected in 2-, 4-, and 6-day-old subtidal biofilms by using AHLs reporter strains.(More)
The aerobic and anaerobic biodegradation of polyethylene glycols (PEGs) in a model wastewater was investigated employing sludge microbes from Xiamen Terylene plant. The effect of molecular weight (MW) on the aerobic/anaerobic biodegradation of PEGs was assessed by performing shake flasks/sealed flasks experiments, respectively, using organic model(More)
Batch verification is a method devised to verify multiple signatures as a whole simultaneously. In literatures, we can see that some conventional batch verification schemes cannot effectively and efficiently identity bad signatures. Small Exponent test, a popular batch verification method, has its own problems, e.g., after a test, bad signatures still exist(More)
There are currently numerous practical applications to improve the effectiveness of Radio Frequency Identification (RFID) Systems. RFID provides an efficient identification for shipping and receiving goods. In warehouse management, RFID mechanisms can be used to check whether large quantities of goods are presented within a supply-chain system. In a(More)
In the present study, we sequenced the RNA polymerase beta subunit (rpoB) gene of marine Vibrio species and assessed its discriminative power in identifying vibrios. Both the rpoB and 16S rRNA sequences of 29 phenotypically different Vibrio strains isolated from coastal waters were determined. Molecular and phylogenetic comparisons of the sequences of these(More)
