Pathogenic germs have developed an increasing resistance toward many
antibiotics which form a true problem for human being ,because these germs can transport to him by
many ways such as water ,food and air that may cause many dangerous diseases to
human being.
The aim of this study is to investigate the effectiveness of extractions prepared from different parts of the
flowing plants: Olea europea Linn(Oleaceae) , Myrtus communis Linn(Liliaceae) ,Majorana syriacus
Linn (Laminaceae), Zingiber officinale Linn(Zingiberaceae),and Achillea falcata Linn(Asteraceae), against
Pseudomonas Aeruginosa.
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.
Pyocyanin was extracted from cultures of Pseudomonas
aeruginosa, which was isolated from sea water by chloroform.
Results study the effect of pyocyanin against human pathogenic
bacteria, which were isolated from Al-Assad hospital laboratory in
La
ttakia, with disk diffusion method showed that pyocyanin has
antibacterial activity against Gram- positive bacteria.
The antibacterial activity of Golden henbane (Hyoscyamus aureus) on
several species of bacteria: Pseudomonas aeruginosa, Staphylococcus
aureus and Escherichia coli was determined. Samples of H. aureus
plants were collected from six locations in southern Syria. The extract
of roots and leaves of H. aureus were prepared at concentrations.
