Optimization of the slaughterhouse water treatment rate by a new Marinobacter carbonoclasticus SF and its biosurfactant
The aim of this study consists of the production of a bio-surfactant from a new bacterial strain, Marinobacter hydrocarbono clasticus SF (96.76 % simila-rity) isolated from soil contaminated by hydrocarbons in Hassi-Messaoud. (Southern Algeria) to treat liquid effluent from slaughterhouse water. The characteristics of organic matter biodegradation tests were discussed. Despite the high pollutant load and the unfavorable Physico-chemical composition of the effluent, the specific growth rate of the isolated strain after 10 days of incubation in the range of 0-30 g L-1 of NaCl was at neutral pH 7.4 and temperature of 45 ?C. The best bio-surfactant production yield was obtained after 72 h of incubation and under the optimal production conditions such as diesel as carbon source, ammonium chloride as nitrogen source, and a C/N ration of 5. The bio-surfactant produced is of glycolipid type with a low critical micellar concentration (CMC), good emulsifying power, and chemical and functional stability. Significant pollutant removal efficiency was obtained using the bacterial strain (up to 82 %) and the bio-surfactant (up to 96 %). Several anions, such as nitrates, phosphates, ammonium, and suspended solids, were measured.
