Xanthan Production from Olive-Mill Wastewaters
Olive mill wastewaters (OMW) are a by-product from olive oil manufacture that cause environmental pollution. These wastes have been used as substrate for the production of the extracellular polysaccharide xanthan by Xanthomonas campestris NRRL 31459-S4L41. Growth and xanthan production on dilute OMW as a sole source of nutrients were obtained at OMW concentrations below 60%, yielding a maxima1 ...
متن کاملAssessment of a New Silicon Carbide Tubular Honeycomb Membrane for Treatment of Olive Mill Wastewaters
Extremely high removals of total suspended solids and oil and grease were obtained when olive mill wastewaters were filtered using new silicon carbide tubular membranes. These new membranes were used at constant permeate flux to treat real olive mill wastewaters at pilot scale. The filtration conditions were evaluated and optimized in terms of the selection of the permeate flux and flux mainten...
متن کاملExisting and emerging technologies for the treatment of olive oil mill wastewaters
Olive oil mill wastewaters (OOMW) represent a significant environmental problem especially in the Mediterranean, the main olive oil production region in the world. Characterization of OOMW is carried out by determination of various parameters, such as BOD5, COD and content of total phenols. The aim of this paper is to evaluate existing (physical, biological etc.) and emerging technologies for a...
متن کاملThe effect of olive mill wastewaters variability on xanthan production.
AIMS Xanthan production by Xanthomonas campestris from several olive mill wastewaters (OMW) was investigated. METHODS AND RESULTS Maximum xanthan production of 4 g l(-1) was obtained in media with 50% OMW as sole source of nutrients. OMW storage decreased effluent quality for xanthan production. The range of effluent concentration for X. campestris growth and xanthan production varied dependi...
متن کاملBoron-doped diamond anodic treatment of olive mill wastewaters: statistical analysis, kinetic modeling and biodegradability.
The electrochemical treatment of olive mill wastewaters (OMW) over boron-doped diamond (BDD) electrodes was investigated. A factorial design methodology was implemented to evaluate the statistically important operating parameters, amongst initial COD load (1000-5000 mg/L), treatment time (1-4h), current intensity (10-20A), initial pH (4-6) and the use of 500 mg/L H(2)O(2) as an additional oxida...
