Microbial communities regulate various collective functions using molecular signaling circuits known as quorum sensing. Understanding and modeling of quorum sensing regulation is essential to design nano-networks and enable communication and coordination among nano-machines. In this paper, a stochastic queuing model of quorum sensing is developed, inspired by known biological processes. The dynamics...
The chemical surfactant Tween 80 and biosurfactant rhamnolipid were added to the solid-state fermentation processes of a strain of actinomycete Streptomyces badius. The extra cellular amylase, protease, carboxy methyl cellulose enzyme (CMCase) and xylanase were analyzed during the fermentation process. In addition, the pH of the fermentation substrate, microbial population and the degradation of the...
The phenol-polluted air was degraded by aerobic granules at a high phenol loading rate and the characteristics of aerobic granules were investigated. The morphology and structure of aerobic granule changed greatly when they degraded phenol-polluted air. The white bamboo-shaped filamentous bacteria grown were completely covered on the surface of aerobic granules at the phenol loading rate of 1.5 kg...
Upon entering the soil environment, extracellular DNA is subjected to dynamic biological, physical, and chemical factors that determine its fate. This review concerns the fate of both recombinant and non-recombinant sources of DNA. A schematic of DNA cycling coupled with genetic transformation is presented to understand its behavior in soil. Extracellular DNA may persist through cation bridging onto...
Summary form only given. Carrageenase producing halophilic bacteria were isolated from seawater and sediment samples collected from the vicinity of seaweed meadow, all along the South West coast of India. Two isolates, YK-C-1 and YK-C-2, producing large amount of extracellular carrageenase were selected for purification of enzyme. Correlation study of enzyme production with growth curve of the aforesaid...
