Abstract AR
تم في هذا البحث فحص مستخلصات المذيبات العضوية (ثنائي اثيل الايثر، خلات الاثيل و الكحول الإثيلي) للريفولاريا و الأسيلاتوريا سالاينا التي تم تجميعها من ساحل مدينة مصراتة ليبيا على نمو 6 أنواع من البكتيريا الممرضة sp., E.
faecalisAcinetobacter P.
aeruginosa, S.
aureus, E.
coli و P.
Mirabilis.
و لقد تم اختبار تأثير هذه المستخلصات باستخدام طريقتي انتشار حفر الاجار (agar well diffusion) و انتشار القرص (disc diffusion).
و لقد تبين من هذه الدراسة أن مستخلص ثنائي اثيل الايثر للريفولاريا له تأثير مثبط على نمو P.
Mirabilis (5mm) و على Acinetobacter sp.
(5mm)، في حين أن مستخلص خلات الاثيل له تأثير أقل على نمو P.
Mirabilis (2mm) و على Acinetobacter sp.
(3mm).
أما مستخلص الكحول الاثيلي للريفولاريا فلم يكن له أي تأثير على أي نوع من البكتيريا المدروسة.
بالنسبة للأسيلاتوريا سالاينا فإن مستخلص ثنائي أثيل الإيثر أظهر تأثير بسيط على نمو Acinetobacter sp.
(2mm).
أما المستخلصين الآخرين فلم يكن لهما أي تأثير مثبط على نمو أي نوع من البكتيريا المدروسة.
Abstract EN
Objectives : in vitro screening of organic solvent (diethyl ether, ethyl acetate and ethanol) extracts of Rivularia species and Oscillatory saline were carried out against some pathogenic bacteria E.
coli, S.
aureus, P.
aeruginosa, E.
faecalis, Acinetobacter species and P.
mirabilis.
Methods : Two marine cyanobacteria Oscillatoria salina and Rivularia species were collected from Mediterranean Sea shore, Maserati, Libya.
Both cyanobacteria strains were extracted with diethyl ether, ethyl acetate and ethanol.
In vitro screening of antibacterial activity of the crude extracts was carried out against six common pathogenic bacteria E.
coli, S.
aureus,..aeruginosa, E.
faecalis, p Acinetobacter species and P.
mirabilis.
The extracts were tested in compliance with the agar well diffusion and disc diffusion method for their antibacterial activity.
Results : diethyl ether extract of Rivularia species showed moderate inhibitory activity against P.
mirabilis (5mm) and Acinetobacter species (5mm) and ethylacetate extract of that species showed little activity against Acinetobacter species (3mm) P.
mirabilis (2mm).
Ethanol extract of Rivularia species showed no activity to that selected bacteria.
Diethyl ether extract of Oscillatory saline showed little activity only against Acinetobacter species (2mm) and the remaining two solvent extracts had shown no activity against that above mentioned pathogenic bacteria.
Conclusion : diethyl ether crude extract of Rivularia species possessed noticeable antibacterial activity against gram negative bacteria when compared with standard Ampicillin and Streptomycin.
It is evident from the present study that the diethyl ether and ethyl acetate extract of Rivularia species could be utilized as an antibacterial agent in pharmaceutical industry.
