Effective degradation of κ-carrageenan by isolated Thalassospira sp. fjfst-332 is reported for the first time in this paper. It was identified by 16S rDNA sequencing and morphological observation using Transmission Electron Microscopy (TEM). Based on a Plackett-Burman design for significant variables, Box-Behnken experimental design and response surface(More)
BACKGROUND The objective of this study was to characterize the agarase from a newly isolated agarolytic bacterium Thalassospira profundimaris fst-13007. RESULTS Agarase-fst was purified to homogeneity which apparent molecular weight was 66.2 kDa. Its activity was optimal at 45 °C and pH 8 and was stable at pH 5-9 or 30-50 °C. Agarase-fst required Mn(2+)(More)
Adaptive failure detection requires that failure detectors can dynamically adjust the detecting quality according to the variations of applications and the load of the network. Because of the instability of the network, failure detectors without adaptive mechanism can not meet the requirements of QoS of applications all the time. Detection speed and(More)
