In recent years, vessels have been discovered that contain the remains of wine with an age close to years. It is unclear whether, in ancient times, humans accidentally stumbled across fermented beverages like wine or beer, or was it a product intended as such.

Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms — yeasts or bacteria —under anaerobic conditions. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term fermentation sometimes refers specifically to the chemical conversion of sugars into ethanol , producing alcoholic drinks such as wine , beer , and cider.

The Role of Yeasts in Fermentation Processes
Heijnen b and R. E-mail: henk. This chapter deals with fermentation processes, converting low cost renewable feedstocks into valuable bio-products, with the help of microorganisms or mammalian cells in bioreactors or fermenters. In industrial vessels, the volumetric conversion rate, i. In special processes where the growth of the cells is marginal, intensification is possible by active cell retention. A comparison with chemical process intensification reveals that the same four main principles are valid, i.
GEA fermentation systems are custom designed for the cultivation of microbial, yeast and fungal products. These processes are typically very dynamic; they have shorter run times because of faster cell doubling times and higher oxygen uptake requirements OUR , translating into higher airflow and agitation requirements. Consequently, these types of micro-organisms grow to higher cell densities and require better temperature control as a result of the heat generated from higher respiration rates. GEA has been developing and building fermentation systems for the cultivation of micro-organisms, human or animal cells for more than 20 years. Whether for individual fermenters or multi-stage fermentation systems, manufacturers repeatedly put their trust in GEA's efficient, customized plant.
Our bioreactor line represents the essence of our expert knowledge and has been designed with the utmost care. Whether for bacterial fermentation or cell culture, a Bilfinger bioreactor offers the right solution. An intelligent module system combines the advantages of series-manufactured products with the benefits of bespoke solutions. Established and reliable modules are available for all main functions. The customer can select what he needs to assemble a system to perfectly match his requirements. The module system offers short lead times and delivery periods due to the fact that the majority of engineering and development of the module system is already finished.

А как же автоматическое отключение. Стратмор задумался. - Должно быть, где-то замыкание. Желтый сигнал тревоги вспыхнул над шифровалкой, и свет, пульсируя, прерывистыми пятнами упал налицо коммандера. - Может, отключить его самим? - предложила Сьюзан.
