Economic losses resulting from the impact of brucellosis on animals have
increased, which is reflected in turn on humans. Brucella is pathogenic bacteria
shared by humans and pet animals. They still pose a significant risk that
threatens health an
d economics in Syria. Many efforts have focused to prevent
the spread of brucellosis disease, by resorting to the use of vaccines prepared
from Brucella strains, where now the target is preparation of vaccine
components proteins of Brucella can be used as a vaccine or an improved
traditional vaccine.
This research was conducted at the Faculty of Agriculture, Department of
Food Science laboratories to isolate lactic acid bacteria from some Syrian milk
products (milk, yogurt, cheese) and determine some morphological,
physiological characteristic and the ability of these isolates to ferment sugars.
Isolation and identification of Pseudomonas aeruginosa was screened from
15 samples of Syrian oily-soils to determine the ability to produce Lipase
enzyme by Cetermide Agar, Tributrin Agar and Brain Heart Broth during
2007-2008 AD. The results sho
wed that there were grown colonies with color of
green or yellow-green surrounded with different diameter of clear zone in three
samples and the identification by Mowasat Hospital revealed that it was
Pseudomonas aeruginosa In addition, the results showed that the optimum
conditions to produce lipase was 35 Cº with the pH degree of 8 and the time of
production of lipase with highest activity of 63.3% was three days in
submerged culture during the optimum conditions. These results illustrated the
important of this isolates to produce and control lipase for industrial
production.
Since the beginning of the twentieth century, researchers have isolated and
dentified spreaded and adapted yeasts to variow environmental conditions and
the types of the mediums in which they graw. The industrial features of the
isolated genera, e
specially those used in the food processing and the stability of
their genetic characteristics were studied. Yeasts in medical and industrial
fields were also improved.
This research was conducted at the Department of Food Science,
Faculty of Agriculture and National commission for posterity
energy. Twenty kg of apple juice concentrate (70%) were tooked
from company of Natural Aljabal Juice from AL-suidaa
Govern
orate and prarerd two concentarate (15% and 35%) by using
distilled –sterlization water according to pirson .
Oleic acid is a fatty acid known as omega-9, which is found naturally in many plant
sources and animal products and is found in the form of tri-glycerides (oleic acid esters). In
this research, the oleic acid was isolated and purified with a high d
egree of purity up to
99% of the fatty acids extracted from olive oil, corn oil and palm oil with a yield of at least
87% of its percentage in the oils used by the use of crystalline urea as well as crystalline
selective cooling . GC-FID was also used for direct quantitative analysis of oleic acid and
other fatty acids.
