Agitation-Aeration in Submerged Fermentation
For the successful operation of aerobic fermentations it is essential to supply the microorganiisms with sufficient oxygen to meet their requirements at any stage in the process. Failure to supply enough oxygen may lead to undesirable changes in enzymatic makeup (Rolinson, 1952) or death of the organisms (Hromatka et al., 1951), with a subsequent lower yield of the desired product. In general, ...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولObservations on a laboratory method for submerged acetic fermentation.
Submerged acetic fermentation experiments were performed for the purpose of determining the conditions under which this type of fermentation should be conducted under laboratory conditions. The apparatus used consisted of a set of glass tubes provided with air spargers. Acetobacter acetigenum was found to be the most suitable bacterium among six Acetobacter compared under submerged acetic ferme...
متن کاملAeration of Bacillus anthracis in submerged fermentation.
An investigationi was undertaken to determine the oxygen absorption rates of a submerged culture of Bacillus anthracis at all stages of its growth cycle. The determination of oxygen absorption rates of a pathogenic fermentation such as this by analysis of the exhaust gases seemed to present fewer technical difficulties than did those methods that depended upon polarographic determination of dis...
