چکیده

چربی‌های میکروبی قابلیت استفاده در سوخت­های زیستی، صنایع دارویی و غذایی دارند. تولید و کاربرد این چربی‌های میکروبی در مقایسه با روغن­های گیاهی در حال افزایش است. هدف این تحقیق تولید چربی میکروبی توسط مخمر یارروویا لیپولیتیکا CBS6303 از گلوکز و بررسی نیم رخ اسیدهای چرب آن برای تعیین قابلیت سوخت­ زیستی بود. بیشترین مقدار تولید چربی و وزن خشک به ترتیب با مقدار 1/42 و 7 گرم در لیتر پس از سه روز بدست آمد. چربی تولید شده توسط یارروویا لیپولیتیکا از گلوکز دارای اسیدهای چرب با قابلیت استفاده به عنوان سوخت زیستی می­باشد که شامل اسید اولئیک (34/71 درصد)، اسید لینولئیک (19/45 درصد)، اسید پالمیتیک (17/05درصد)، اسید استئاریک (6/12 درصد) و اسید میریستیک (0/82 درصد) بود.

چکیده [English]

Microbial lipids have a capacity to use in biofuels, pharmaceutical and nutrition industries. The production and application of these lipids are increasing in compare with vegetable oils. The production of microbial lipid by Yarrowia lipolytica CBS6303 from glucose and investigation of its fatty acids profile to determine its biofuel potential were the aims of this study. Maximum lipid production and dry weight were obtained 1.42 and 7 g/L after three days, respectively. The produced lipid by Y. lipolytica from glucose contains fatty acids that can be used as biofuel like oleic acid (34.71%), linoleic acid (19.45%), palmitic acid (17.05%), stearic acid (6.12%) and myristic acid (0.82%).
