تنتج معامل الألبان و الأجبان كميات هائلة من مصل اللبن و الجبن ترمـى نحـو 90 % منهـا إلـى الصرف الصحي دون الاستفادة منها. يحتوي مصل اللبن و الجبن على كل مكونات الحليب عدا الكـازئين و المواد الدسمة التي تصرف إلى صناعة الجبن و اللبن و الزبدة. يحتوي مـصل الحليـب علـى لاكتـوز و ألبومينات و غلوبولينات و إنزيمات و أملاح و فيتامينات، بالإضافة إلى الجزء المتبقي من الكازئين و الموادالدسمة . يمكن الاستفادة من مصل اللبن و الجبن كغذاء متكامل لما يحتويه من المركبات الثمينـة سـابقة الذكر، بتكثيفه أو تجفيفه و إضافته إلى مختلف الصناعات الغذائية و المعجنات. قمنا في هذا البحث بتحليـل مصل اللبن و الجبن بطرائق عدة، و بتكثيف المصل و تجميده لرفع نسبة المكونات، و من ثم الاستفادة منـه كبيئة مغذية للنموات الفطرية لإنتاج حمض الليمون و البنيسيلينات و استخلاص الأرغوسترول و الحمـوض الأمينية، و استخدمنا الكروماتوغرافيا السائلة عالية الأداء لتحديد المركبات الناتجة.
Dairies and cheeses factories produce terrific quantities of whey in which about 90% of them pelts into the sewerage system without making any useful of them. Due to the valuable ingredients in whey (cheese, milk and butter). The content can be separated and extracted in order to be added as a nutrient environment in food industry. The resultant compounds (citric acid , penicillin, amino acids and ergosterol) were identified using HPLC technique.

Sixty yeasts spp. were isolated from samples of whey which collected from
different locations in Syria. These yeasts were classified morphologically
according to Barnett’s and physiologically by API technique to identify the
species of Yeasts, whe
re had found 10 classified yeasts as follows:
Candida krusei is the most of yeasts which founded in whey with 21.66 %,
and in the Second rank is Candida lusitaniae with 16.66 %. the third rank came
(Geotrichum capitatum, Saccharomyces cerevisiae, Rhodotorula minuta) with
11.66%, after that the Candida magnolia is ranked in the fourth rank by
distributing with 8.33%. as soon as the Candida famata came in the fifth rank
with 6.66%, and in the sixth rank we founded Candida lipolytica with 5%,
finally the Rhodotorula. mucilaginosa and Candida. kefyr came in the last rank
with 3.33%, so we noticed the variety of the yeasts in the studied locations in
Syria.
This research was conducted in Lattakia province during the year 2012 first, to
identify the current status of the production residues and agro-processing materials in the
province and, second, to introduce modern methods of taking advantage of the
m and
raising their nutritional value.
Results showed that, the most agricultural residues are not optimally used, instead,
they were disposed and accumulated causing substantial losses and environmental
pollution.
Results showed that, the investment average ratio of legume, vegetables, cereals, and
fruit trees were 75%, 65%, 60% and 40% consensually
This research conclusion shows that, the optimal use of barley residue is a source of
cheap protein units that are necessary for animals feeds; where the cost per unit of digested
protein resulting from urea treated hays amounts to 0.5 S.Y.P. This amount represents one
fifth of the cost of protein unit from barley.
Also, the use of wheat straw in the cultivation of oyster mushrooms achieve
significant economic results, the net profit resulting from the cultivation area of 10 m2 of
oyster mushrooms using 30 kg of wheat straw was about 81000 S.P.
In addition to that, the research results show the importance of agricultural waste in
biogas production and the resulting compost, which in turn has achieved excellent results
when fertilizing crops with it. The increase in the yield of maize, wheat, faba bean and
vegetables were 35.7%, 12.5%. 6.6% and 14.1-20.6% consensually.
The research aims to study the effect of certain organic and amino
compounds in the growth and production of tomato under green

The process of soil restoration is one of the most important methods of vertical and
horizontal expansion in the agricultural sector; it works to increase the effectiveness of
investments on the one hand, and to accelerate mass production on the ot
her hand. The
processes of reclamating lands include a big number of important procedures that directly
affect the utilization of agricultural lands. On top of these procedures come: constructing
dams, building modern systems and nets for irrigation and sanitation, reclamating saline
soil, protecting soil from drift and erosion, stopping encroachment of desert, settling land
slopes, getting rid of stones, building terraces in slopes, drilling artesian wells, improving
pastures, and cultivation green belts.
The Syrian government developed a multiple-target-agricultural strategy including
primarily increasing the reclaimed areas, using modern techniques for irrigation (drip and
spray), as well as providing water for irrigation through the construction of several dams.
This made the total irrigated area in the country about 1399 thousand hectares in 2011, i.e.
about 24.5% of the cultivated land. The percentage of irrigated areas using this method is
about 22.4% of the total irrigated area in the country. These actions positively affected the
productivity of crops, vegetables and fruit trees, so that the winter irrigated crops reached
5–10 times the non–irrigated crops, and the summer irrigated crops reached 4 times the
non–irrigated crops.
The Ornamental Plants (Altlfona) of important economic cultivations were introduced to the recently Syrian agriculture "as one of the most important alternative cultivations, especially" in the coastal strip, as a prospective areas for the spread of
these agriculture This research has concentrated on the economical properties and the profits resulting from Carnation plantation in Latakia Governorate studying the productivity cost and the indicatives of economical feasibility based on data and statements gathered from site of research (Arab Almelik),and relying, in determining wages and materials costs, on the current market prices in 2015.
In this research, we have sought to achieve the following targets:
- Studying the reality the production of Ornamental Plants in the Syria, in general, and Latakia Governorate, in particular, during the period from 2005 to 2013.
- Calculating the productivity cost of Altlfona plants in Latakia Governorate.
- Making an economical evaluation of Altlfona plants in Latakia Governorate.
In conclusion, we have reached the following result:
• Totally achieved net profit per annum from one greenhouse of Altlfona plantation amounted to 668212.7Syrian Pounds.
• Profitability Coefficient in proportion to invested capital has amounted to 27.19% and to 49.67% in proportion to the productivity cost.
• Time indicator of Capital recovery for Altlfona has amounted to 3.67 years.
