يتناول هذا البحث إمكانية إنتاج كل من الميتانول و الايتانول من مياه الجفت OMW((OMW: Olive Mill Wastewater، و ذلك خلال عملية معالجة حيوية لاهوائية (تخمر) باستخدام جراثيم ممرضة و أخرى معزولة بحرياً. أظهرت النتائج أنه عند تخمر مياه الجفت باستخدام جراثيم الـSalmonella sp. كان أعلى تركيز للميتانول (g/lµ5658.308) عند تركيز مياه الجفت 7.5% في وسط التخمر، و أعلى تركيز للايتانول (g/lµ49.132) عند تركيز17.5% لمياه الجفت. في حين أعطت جراثيم الـPseudomonas sp. أعلى تركيز للميتانول g/l)µ603.76) و الايتانول (g/lµ688.71) عند تركيز 17.5%لمياه الجفت. بينت النتائج قدرة الجراثيم المعزولة من مياه البحر على إنتاج الميتانول و الايتانول؛ بالنسبة لجراثيم X3 تبين وجود علاقة طردية بين ارتفاع تراكيز مياه الجفت (15 , 35,50 )% و ارتفاع تراكيز الميتانول (UL, g/lµ130.406, g/lµ1353.244) على التوالي، على عكس الايتانول الذي كان تحت حدود الكشف (Under limited: UL).
In this study, we review the possibility of production both ethanol and methanol from OMW(OMW: Olive Mill Wastewater), fermented using pathogenic bacteria and isolated marine bacteria. The results showed that when using Salmonella sp. bacteria, the highest values of methanol (5658.308 μg /l) appear at 7.5% concentration of the OMW, and the higher concentration of ethanol (49.132 μg/l) at a concentration of 17.5% fermentation of OMW. While Pseudomonas sp. produced the highest concentration of methanol (603.76μ g/l) and ethanol (688.71μg /l) at 17.5% for OMW. The results of this research showedthe ability of the bacteria isolated from sea water in producing the above mentioned alcohols; for example the X3 bacteria displayed a direct correlation between high concentrations of OMW (15 , 35 , 50)% and the high concentrations of produced methanol (UL, 130.406μg/l, 1353.244μg/l ), apposite to ethanol which was under the detection limits (under limited: UL).

The research aims to study the economic efficiency of olive mill wastewater
(OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in
Lattakia Governorate, depending on the descriptive analytical method,And found the
results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it
posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP ,
The coefficient of profitability compared to the cost of production (about 41.32%)%, while
the profitability coefficient was compared to the capital invested approximately 42.98%.
3,4-dihydroxybenzoic acid is one of phenolic compounds that exists in olive mill waste water (OMWW) and different industrial wastewater.Commercially activated charcoal was studied as absorbent of polyphenols. The value of specific surface area was 73
6.7189 m2/g. Equilibriums of 3,4-dihyroxybenzoic acid from aqueous solutions on four different particle sizes of the adsorbent with diameters ranged A(1000-2000), B(500-1000), C(250-500), D(125-250)m was examined at different initial concentrations ofabsorbate. The experimental data were analyzed using the Langmuir and Freundlich isotherm models. Both the isotherm models fit the adsorption data. Monolayer absorption capacities Q0 calculated from Langmuir equation were (0.36, 0.23, 0.34, 0.35mmol/g) for the different granular activated carbon sizes (A,B,C,D) respectively. The values of constant Kf calculated from Freundlich equation were (0.75, 0.61, 0.76, 0.79mmol/g) for the four sizes of granular activated carbon (A,B,C,D) respectively.
The results show that the charcoal activated carbon can be used as absorbent for polyphenol compounds.
The Mediterranean region is world’s leading olive growing area. A large amount of
liquid waste results from olive oil extraction these wastewaters have a different effects an
environmental . In this study, four fungal isolates from Samples of soil
Polluted by olive
mill wastewater ,this isolates follow to several types from deuteromycetes, they are follow
to this types : Humicola sp., paecilomyces javanicus, Aspergillus terreus, Aspergillus
flavus. They isolated them on tow media (PDA, CzA) and identify them on colony
character ,Biometric and compare them with reference studies.
A research was carried out at Al-Sanouber research station in
Lattakia in 2013/2014 season ,The research included six treatments
with four replicates for each treatment. Six treatments used of
OMWW (0 , 10 , 20 , 30 , 40 , 50) l/m2. The OMWW has b
een
added 40 days before planting. Samples of soil have been taken
before adding OMWW, then after one and two months from
planting, and at the end of the season in order to make some
physical and chemical analysis and also to know the concentration
of some micro elements .
