Use of Swiss Cheese Whey Permeate by Kluyveromyces fragilis and Mixed Culture of Rhodopseudomonas sphaeroides and Bacillus megaterium

Production and purification of lactase of Kluyveromyces fragilis from whey

Enhanced Conversion of Lactose to Glycerol by Kluyveromyces fragilis Utilizing Whey Permeate as a Substrate.

Kluyveromyces fragilis (CBS 397) is a nonhalophilic yeast which is capable of lactose utilization from whey permeate and high glycerol production under anaerobic growth conditions. However, the optimum yields of glycerol (11.6 mg/ml of whey permeate medium) obtained in this study occurred only in the presence of 1% Na(2)SO(3) as a steering agent. The use of other concentrations of Na(2)SO(3), a...

Fermentation of lactose to ethanol in cheese whey permeate and concentrated permeate by engineered Escherichia coli

BACKGROUND Whey permeate is a lactose-rich effluent remaining after protein extraction from milk-resulting cheese whey, an abundant dairy waste. The lactose to ethanol fermentation can complete whey valorization chain by decreasing dairy waste polluting potential, due to its nutritional load, and producing a biofuel from renewable source at the same time. Wild type and engineered microorganisms...

second language acquisition of telicity and aspect by persian learners of english

این تحقیق از دو قسمت اصلی تشکیل شده است: در قسمت اول فراگیری ختمیت به ویژه درک و تولید اینگونه جملات توسط فراگیران ایرانی زبان انگلیسی مورد بررسی قرار گرفته است. قضاوت تعدادی انگلیسی زبان بر روی این جملات نیز هدفی دیگر بود که در این رساله بررسی شده است. از موضوعات دیگر تفاوت بین نشانه های ختمیت در زبان انگلیسی و فارسی و تاثیر زبان اول فراگیران در درک و تولید اینگونه جملات است. در قسمت دوم استفا...
