Abstract

A strain of Saccharomyces cerevisiae was taken from Shabaa yeast manufactory in Damascus and it was grown in a suitable culture in order to test its ability to uptake heavy metals. A comparison was made on the ability of Saccharomyces cerevisiae to uptake Cadmium and Cobalt in different growing conditions, where three concentrations were used for each metal at three pH degrees and three temperatures. The grown Saccharomyces cerevisiae was able to uptake both Cobalt and Cadmium individually and combined; the highest uptake amount of Cobalt reached 1.99 ppm from 2 ppm, and for Cadmium 0.48 ppm from 0.5 ppm. It was noticed that the uptake rate increased when the two metals were in combination, and temperatures were 5 c and 28 c, and pH 4 and 9, which are best conditions. This biotechnology can be applied using Saccharomyces cerevisiae to uptake heavy metals from industrial wastewater.

الملخص

أُخذت سلالة خميرة الخبز Saccharomyces cerevisiae من معمل خميرة شبعا في دمشق ونُمّيت على الوسط المناسب بهدف اختبار قدرتها على إزالة المعادن الثقيلة، وأُجريت مقارنة قدرة خميرة الخبز على إزالة الكادميوم والكوبلت في شروط تنمية متباينة حيث استُعمل ثلاثة تركيزات لكل معدن عند ثلاث قيم pH وثلاث درجات حرارة. تمكنت خميرة الخبز المنماة من إزالة كلاً من الكوبلت والكادميوم بشكل مفرد ومن إزالتهما مختلطين، فبلغت أعلى إزالة من الكوبلت 1.99 جزءاً في المليون من جزأين في المليون، ومن الكادميوم 0.48 جزءاً في المليون من 0.5 جزء في المليون، ولوحظ ازدياد معدَّل الإزالة قليلاً بوجود المعدنين معاً، كما كانت درجات الحرارة 5 و28 م وقيم pH 4 و9 ظروفاً فضلى للإزالة. ويمكن تطبيق هذه التقانة الحيوية باستعمال خميرة الخبز في إزالة المعادن الثقيلة من مياه الصرف الصناعي.
