cesss to a rye-grass pasture during 4 h/d. Brewery supplementation at the 75% level increased blood pH (P<0.01), reduced glucose (P<0.001), and tended to increase protein (P=0.10). Besides, there was a general correlation within glucose and protein, glucose and glutamic-oxaloacetic transaminase (GOT), pH and GOT, protein and GOT. In conclusion, high levels of brewery supplementation increase bl...

The investigations were made in a loop bioreactor, where biomass was immobilized in the ceramic carrier. The influence of the internal circulation rate on the biodegradation efficiency of brewery wastes by immobilized biomass and on production of surplus sludge was examined. The rates of the internal circulation were 12, 38, 50 dm·h. The experiments were performed at constant loading rate of th...

Anaerobic modeling is a useful tool to describe and simulate the condition and behaviour of anaerobic treatment units for better effluent quality and biogas generation. The present investigation deals with the anaerobic treatment of brewery wastewater with varying organic loads. The chemical oxygen demand (COD) and total suspended solids (TSS) of the influent and effluent of the bioreactor were...

The brewing industries continuously generate lot of solid waste of which spent grains is a major by product. The present utilization method of Brewery Spent Grains (BSG) in food chain makes it imminently necessary to explore the adverse effect of the waste on humans. This paper focuses on investigating the effects of BSG formulated diet on haematological, biochemical, histological and growth pe...

Brewing is the process is for production of beer [1,2]. It is said that for every 1 liter of beer production approximate 10 liters of water is used [3]. The water in any brewery is typically used for brewing, rising and cooling process [3]. The various steps that are involved in brewing process are malt production and handling, worth preparation, fermentation, filtration, CIP and finally packag...

The major cause of production loss in brewery industry is the Machine failures which stopped the production operations. The Markov approach is used for studying the Performance modeling and Availability analysis of a Malt Mill system in brewery plant by using the concept of performance analysis. For carrying out analysis, transition diagrams (TD) for various subsystems in the brewery plant are ...

Characteristic of the beer production process is the uncertainty caused by the complex biological raw materials and the yeast, a living organism. This uncertainty is exempliied by the fact that predicting the speed of the beer fermentation process is a non-trivial task. We employ neural network and decision tree learning to predict the speed of the beer fermentation process. We use two data set...

During brewery handling, production strains of yeast must respond to fluctuations in dissolved oxygen concentration, pH, osmolarity, ethanol concentration, nutrient supply and temperature. Fermentation performance of brewing yeast strains is dependent on their ability to adapt to these changes, particularly during batch brewery fermentation which involves the recycling (repitching) of a single ...

The brewery industry generates waste that could be used to yield a natural extract containing bioactive phenolic compounds. We compared two methods of purifying the crude extract-solid-phase extraction (SPE) and supercritical fluid extraction (SFE)--with the aim of improving the quality of the final extract for potential use as safe food additive, functional food ingredient, or nutraceutical. T...
