Microencapsulation by Membrane Emulsification of Biophenols Recovered from Olive Mill Wastewaters
Biophenols are highly prized for their free radical scavenging and antioxidant activities. Olive mill wastewaters (OMWWs) are rich in biophenols. For this reason, there is a growing interest in the recovery and valorization of these compounds. Applications for the encapsulation have increased in the food industry as well as the pharmaceutical and cosmetic fields, among others. Advancements in m...
متن کاملXanthan 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 کاملOptimization of energy costs in the pretreatment of olive mill wastewaters by electrocoagulation.
In this study, the electrocoagulation process was evaluated as a pretreatment process for olive mill wastewaters. Aluminium (Al) and iron (Fe) electrodes, several contact times and 0.5, 1 and 2 A currents were used to compare chemical oxygen demand (COD) removal efficiencies for each case. The optimum contact time and current were 45 minutes and 1 A, respectively, which resulted in a COD remova...
