عُزِلَت الكتلة الحيوية النامية في وسط تحلية الزيتون و تم تنميتها على وسط من المخلفات المائية لمعاصر الزيتون غير المعالجة OMW1 و على وسط آخر منها منزوع المعلقات الغنية بالكربون العضوي، باستخدام طريقة التجميد و الترقيد و عزل السائل الطافي OMW1.
The Bio-mass was isolated from the medium of the water olive soaking , and was developed on two medium olive mill wastewater OMW.

Pretreatment is one of the most important stage in olive mill
wastewater (OMWW) plants. Statistically, the cost of chemicals in
pretreatment will be not more than 0.02 €/m³OMWW for some kind of
chemical coagulants such as CaO.
This research aimed to study the effect of various growth conditions
(temperature, culture age and culture medium) on the fatty acids composition
of cytoplasm membrane of 37 isolates of Staphylococcus aureus using Gas
Chromatography-Mass Spectrome
try (GC-MS). Results revealed that the total
number of fatty acids of Staph. aureus was 33. Eight of them were principle and
included: anti-isotetradecanoic acid (aC15:0), octadecanoic acid (C18:0),
eicosanoic acid (C20:0), isotetradecanoic acid (Ci14:0), isotridecanoic acid
(Ci15:0), hexadecanoic acid (C16:0), antisohexa- decanoic acid (Ca17:0) and
octadecenoic acid (C18:1) with a percentage of 33.96, 18.37, 14.94, 7.32, 6.23,
4.14, 3.03 and 2.89%, respectively. The percentage of each of the other fatty
acids was less than 1%. Increasing the incubation temperature was associated
with reducing the percentages of Ca15:0, Ci15:0, C16:0 and C18:1; and
increasing Ca17:0, Ci14:0, C18:0 and C20:0. The increase in incubation period
caused a decrease in C16:0, C18:0, C18:1 and C20:0; and an increase in Ca15:0
and Ca17:0. Moreover, the variation in culture media caused differences in the
percent of Ca15:0, C18:0 and C20:0; while the other fatty acids showed no
changes.
The importance of this study is focused on evaluating the quality of pollutants that are dumped into the sewers associated with the analysis laboratories and the various clinics located in the scientific centers of the University of Aleppo.
The aim behind this study was to isolate and characterize fungi from fermented olive
mill wastewater to determine the superior one that can resist high organic load and total
phenol of fresh Olive Mill Wastewater (OMW).
Two different media Czapak
Dox Agar (CzA) and Potato Dextrose Agar (PDA) were
used for identification of fungi by studying macroscopic and microscopic characteristics.
However, Aspergilluss sclerotiorum, Paecilomyces sniveus and Mucor nircinelloides had
had been identified .
After testing the isolates on fresh olive mill wastewater solid mediums OMWA1
(50%OMW), OMWA2 (75%OMW) and OMWA3 (100%OMW).
Whereas P. niveus proves that was the superior one, which can resist high
concentration of fresh olive mill wastewater.
Since the reaction in the WWPs bioreactors is included in enzymatic
catalytic reactions type, then the kinetic coefficients can be
determined due to Michaelis-Menten model. A tow-parts
computational program was built by means of MS Excell.
