KINETICS PARAMETERS ANALYSIS OF BIOFLOCCULANT PRODUCTION FROM Alcaligenes latus ON THE SUBSTRATE OF HYDROLIZATE OF SOLID WASTE FROM PULP AND PAPER INDUSTRY AND ON GLACOSE

Abstract

There are two kinds of waste being discharged in the pulp and paper Industry, namely wastewater and solid waste which contains Lignocellulosic materials. Lignocellulosic materials are potential to be used as substrate for microbial bioconversion. During the study Alcaligenes latus used the hydrolizate of solid waste from pulp and paper Industry to produce flocculant, which could flocculate wastewater that contained suspended solids. For all the experiments A. latus grew well on solid waste hydrolizate, giving about 2.21 g product substrate and 1.09 g biomass/g substrate. Cultivation on glucose yielded about 4.42 g product substrate and 2.84 g biomass/g substrate. The specific growth rates of bacteria on the substrate of hydrolizate of solid waste from pulp and paper Industry and glucose were 0.05277/h and 0.0237/h, respectively.
