Abstract
Sixteen litres of olive-mill wastewaters (OMW) diluted to 5% organic m atter (d.w.) were inoculated in a fermenter (T=30 degrees C, air flow= 161 min(-1) stirring=100 rpm) with a strain of Azotobacter vinelandii. After 2 weeks the bacterial biomass was separated by centrifugation a nd capsular polysaccharide (CPS) and exopolysaccharides were extracted . The apparent molecular weight of CPS was determined by gel filtratio n. The CPS was entrapped in polyvinyl alcohol membranes which were use d to adsorb cadmium and lead ions from a liquid stream.
