Pilot Scale Production of a Lager Beer from a Grist Containing 50% Unmalted Sorghum

Bacteria, biochemical changes and sensory characterization of sorghum lager beer production

This study was conducted to identify bacteria encountered and some biochemical changes which occurred during the production of sorghum lager beer. Sensory evaluation was also carried out to compare physical properties of the beer with industrially manufactured lager beer. Erwinia, Enterobacter, Bacillus, Flavobacterium, Streptococcus, Acetobacter Lactobacillus, Acinetobacter and Aerococcus spec...

Encapsulation of brewing yeast in alginate/chitosan matrix: lab-scale optimization of lager beer fermentation

Two mathematical models were developed for studying the effect of main fermentation temperature (TMF), immobilized cell mass (MIC) and original wort extract (OE) on beer fermentation with alginate-chitosan microcapsules with a liquid core. During the experiments, the investigated parameters were varied in order to find the optimal conditions for beer fermentation with immobilized cells. The bas...

Production Scale Up of Nanofibers: A Review

A Pilot Study of Syngas Production from Bio-oil Thermal Cracking in a Bubbling Fluidized Bed Reactor

A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

Evidence for a Far East Asian origin of lager beer yeast

Lager-brewing arose in 15th century Bavaria [1] and is nowadays the most popular technique for alcoholic beverage production in the world. The technique is characterized by low temperature fermentation using the domesticated yeast Saccharomyces pastorianus (synonym S. carlsbergensis). It has been clear that the lager yeast is a hybrid with one portion of its genome having originated from S. cer...
