Optimal control of fermentation processes
… main reasons for carrying out research on a beer fermentation process can be summarised as follows: this kind of industry represents an up-to-date example of industrial processes in general, the need to compare and evaluate optimisation methods (well established and "modern") on similar …

Fermentation methods for dextransucrase production
Several fermentation methods for the production of the enzyme dextransucrase have been employed. The theoretical aspects of these fermentation techniques have been given in the early chapters of this thesis together with a brief overview of enzyme biotechnology. A literature survey on cell recycle …

Fermentation studies on Clostridium acetabutylicum
… a laboratory system for the study of the ABE fermentation under laboratory conditions. The development of defined and simple laboratory inoculation and build-up procedures for the ABE process was investigated. A defined spore preparation in distilled water gave solvent yields comparable to the …

Isothermal microwave biology : catalysis and fermentation
… towards simultaneous saccharification and fermentation (SSF), the yeast Saccharomyces cerevisiae was subjected to irradiated microwave fermentations on a glucose substrate. Although inconclusive in terms of rate increase, cell density 1 was comparable across the power range showing that the …

Monitoring lactococcal phages during milk fermentation
… X. The presence of lactococcal phages in the fermentation industry can have detrimental effect on both the acidification capacity and the quality of the final product. Blend X is employed in many production plants around Europe; therefore, it is not unusual for the blend to encounter problems …

Tower Continuous Fermentation of Cellulosic Wastes
… of cellulose to biomass in a novel Tower fermentation system. Ball milled a-cellulose and newspaper were used as model substrates. Five cellulolytic fungi were selected from the literature for their bioconversion abilities. Their optimum pH and temperature for growth were determined on …

Mathematical Modelling of Tower Fermentation Processes
The Fermentation Industries are currently concerned with a number of large-scale processes, including single cell protein production, effluent treatment, and the production of alcoholic beverages. Successful design and optimisation of these new systems is becoming increasingly dependent upon the …

Electrodialysis of acetic acid fermentation broths
… and purify acetate from model solutions and fermentation broths such as vinegar and calcium magnesium acetate (CMA). An initial evaluation of the ED stack with model sodium chloride solutions revealed that increasing the flow rate increased the limiting current density. There appeared to be …

Hindgut fermentation in ruminating Holstein calves
… starch and type of dietary protein on hindgut fermentation were evaluated. Thirty-two Holstein bull calves were fed diets containing variable amounts of orchardgrass hay and a grain mixture. The amount of starch and types of protein were: [L1] low starch, soybean meal (SBM); [L2] low starch, …

The Effect of Fungicide Residues and Yeast Assimilable Nitrogen on Fermentation Kinetics and H2S Production during Cider Fermentation
… demands research-based recommendations for cider fermentation. This study evaluated relationships between the unique chemistry of apples and production of hydrogen sulfide (H2S) in cider fermentations. Yeast assimilable nitrogen (YAN) concentration and composition and residual fungicides influence …

Optimal control of fed-batch fermentation processes
Optimisation of a fed-batch fermentation process typically uses the calculus of variations or Pontryagin's maximum principle to determine an optimal feed rate profile. This often results in a singular control problem and an open loop control structure. The singular feed rate is the optimal feed …

Modification of Fermentation by Exogenous Energy Input
… earth. Yeasts, the microbial driver of ethanol fermentation, evolved on the surface of vegetation and had to adapt to survive photonic assault. Past research has demonstrated that white light affects yeast metabolism along with the ability to entrain circadian rhythms, although no known genetic …

Comparison Study Between Post-Fermentation Stillage and Pre-Fermentation Mash Utilizing Acidification and Steam Explosion Techniques for Cellulose Saccharification
<p>Pre-fermentation mash fiber and post-distillation stillage fiber were examined and compared using a variety of preparatory techniques to determine the better source for cellulose fiber saccharification. Once screened, dried, and diluted to a 10% solution, mash fiber and stillage fiber were …

The Role of Blackberry Grades and Fermentation Methods on Blackberry Kombucha Quality and Aroma Characteristics from Small-Scale Fermentation
… this study aims to develop a simple, small-scale fermentation strategy for blackberry kombucha to determine if and how blackberry grades and fermentation methods impact the final kombucha quality. First, the physicochemical parameters of U.S. No.1 and U.S. No.2 blackberries were analyzed, …
