Evaluation of Fungal Growth on Olive-Mill Wastewaters Treated at High Temperature and by High-Pressure Homogenization
Reuse of olive mill wastewaters (OMWWs) in agriculture represents a significant challenge for health and safety of our planet. Phytotoxic compounds in OMWW generally prohibit use of untreated OMWWs for agricultural irrigation or direct discharge into surface waters. However, pretreated OMWW can have positive effects on chemical and microbiological soil characteristics, to fight against fungal s...
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 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 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 کاملCHEMICAL REACTION AT HIGH TEMPERATURE AND HIGH PRESSURE VI Polymorphic Transition in ZnP, at High Temperature and High Pressure
:1 new pressure-induced modification of zincdiphosphide, ZnP2, has been prepared by the di reel union o(zinc with phosphorus and also through the polymorphic transitions of both monoclinic and tetragonal ZnP2. The application of pressures above 20 kb combined with temperatures above 150'C is required for [be synthesis. The new modification of ZnP2 has a pseuda•cuhic cps[al symmetry with a latti...
