The main portion of the  system consisted of a jacketed cylindrical Pyrex  glass bioreactor where the date syrup was pumped from  its base and the product was received from the top.  Box-Wilson composite rotatable design was  constructed to obtain the proper conditions of  ethanol fermentation [temperature, date syrup  concentration and feeding flow rate]. It is possible  to obtain from this technique a polynomial equation  which describes how these variables affect ethanol  production. The optimum conditions are: Temperature:  29.5º C, Date syrup concentration: 64.47 mg\/cm3,  Feeding flow rate: 200 cm3\/hr.   The study shows that flocculent yeast is more  efficient in continuous ethanol production process  when it is compared with non-flocculent yeast.  Flocculent yeast cells are able to aggregate and make  flocs so that, the cells will remain in the column.  Date syrup was used in this research as a  sugar substrate because it was the available sugar  source in Iraq and usually used in ethanol  production. Maximum conversion of date syrup to  ethanol is 92.99%.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838360270\"\u003e\u003ch3\u003eContinuous Ethanol Fermentation Using Flocculent Yeast\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838360270","offer_id":39469158858845,"sku":"9783838360270","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d8f62d78-30b2-4c77-9cb1-54d09a0e6e86.jpg?v=1758952456","url":"https:\/\/shop.autorenwelt.de\/products\/ethanol-production-from-date-syrup-von-hayder-kh-q-ali-und-zinah-al-azzawi","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
