Özet:

 

Olive oil mill effluent (OOME) is one of the major pollutants produced by the agricultural  industry in Mediterranean countries. The olive oil mills in these countries generate about 2-3 million  tonnes of effluent annually. OOME is a black liquor containing a water-soluble fraction of ripe olives  and water that is used in the process of olive oil extraction. This waste has a high mineral content and  a chemical oxygen demand of 25.000-100.000 mg/l. depending on the olive oil extraction process  used.  This study presents a process for biosurfactant as rhamnolipid production by Pseudomonas sp. from  olive oil mill effluent (OMME). For this purpose, some biosurfactant-producing strains were assayed  and several strains of Pseudomonas sp. were able to grow on OOME as the sole carbon source and  accumulate rhamnolipids. Samples of OOME used as a medium of production were diluted and it was  only necesarry to add NaNO 3 (2.5 g/l) to the medium. The conversion yield was 0.875 g of  rhamnolipid per litre of substrate (OOME). The COD of the OOME was reduced by 50-70% in 72 h.
