Dual biopolymer production and separation from cultures of Bacillus spp.
… new materials for biodegradable plastics, biopolymers provide attractive solutions with their vast range of applications. A challenge in industrial production of biopolymers is their high cost, and one approach to minimise the cost is expanding the number of valuable products obtained from …

The influence of nitrogen and sludge age change in reactor performance and biopolymer production in activated sludge
… and sludge age change in reactor performance and biopolymer production in activated sludge systems. The qualitative and quantitative analyses of the naturally occurring biopolymers were performed and the results were correlated to sludge a settling characteristic and effluent quality. In order to …

The effect of varying several operational parameters on the dewatering characteristics of activated sludge
… settling and dewatering characteristics; (3) biopolymer content can be correlated with sludge dewatering rates such that biopolymer content can be used as a parameter to monitor sludge dewatering characteristics. Results from this study indicated that the shock loadings considered here …

Improvement of D-glucaric acid production in Escherichia coli
… for a plethora of potential uses, including biopolymer production, cancer and diabetes treatment, cholesterol reduction, and as a replacement for polyphosphates in detergents. This molecule was identified in 2004 as a "Top Value-Added Chemical from Biomass" by the U.S. Department of Energy …

Modelling and Simulation of Membrane Bioreactors for Wastewater Treatment
… membrane fouling as a result of adsorption of biopolymers present in the bulk liquid onto and within the membrane, all activated sludge models considered in this thesis are able to predict, with various levels of accuracy, the concentrations of biopolymeric substances, namely soluble microbial …

Production of bioplastic precursors (polyhydroxyalkanoates) from macroalgae
… algal biomass to be used as feedstock for the production of PHAs. The hydrolysates obtained from the non-pretreated algae, and pretreated under optimal conditions, were used as culture medium for fermentation to PHAs with C. necator, and the profiles of substrate consumption, biomass generation …
