Background: Biofilm degradation and fruit juice clarification constitute two highly imperious industrial bioprocesses. Biofilms are the microbial sessile communities embedded in a self-composed polymeric matrix, representing remarkable survival strategy for safeguarding against several dynamic environmental stresses. Quorum sensing inhibition is the subsidence of bacterial cellular communication that impedes their population density and synchrony.Conversely, juice clarification is the breakdown of a semistable emulsion of colloidal plant moieties supporting the insoluble cloudy matter of freshly pressed juice thereby dropping the viscosity and modifying its opacity to an open splotchy look. Enzymatic juice clarification circumvents the comprehensive downstream processing and reduces astringency in taste while improving qualitative characteristics viz. color, viscosity, turbidity and filterability. Methods: In the present investigation, protease was extracted from persuasive microbial consortia screened from mangrove swamplands and chemically characterized by optimization, stability, spectroscopic, kinetic, inhibition and electrophoreticassays. Application studies of protease were performed to test its quorum sensing inhibition ability and efficaciousness in juice clarification of the indigenous, perishable seasonal fruit Mangifera indica, widely acclaimed for its taste, succulence and exotic flavor. Findings: The percent biofilm degradation by Crystal violet method was recorded as 90.5% for test sample and 44.5% for positive control. The percent juice clarification, estimated by Bradford method of protein quantitation, was estimated as 18.1% and 60.3% for test sample and positive control respectively. Coastal tropical biomes are discrete saline shrubland habitats providing idiosyncratic ecostations to diverse microbial communities loaded with hydrolytic enzymes, notably proteases. The escalated cognizance of applications of microbes has solicited the development of newer commercially rewarding biological products in various spheres. Hence microbes from diversified exotic environments have been screened for specific properties expecting to result in novel process applications. Novelty: The present study is valuable in evolving an additional newfangled approach for the above said pre-eminent commercial bioprocesses.
