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 کاملFertilizer NPK from human urine and olive oil mill wastewaters
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...
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 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 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...
