Thymol, an important and advantageous component of many essential oils, has been applied as an antimicrobial agent in animals. To increase the duration of action of this compound in ruminants, it was decided here to prepare a controlled release carrier for thymol. Hydroxy propyl methyl cellulose (HPMC) and ethyl cellulose (EC) were used as the matrix polymer here. Mixtures of thymol with eight ...

Water kefir is a sour, alcoholic, and fruity fermented beverage of which the fermentation is started with water kefir grains. These water kefir grains consist of polysaccharide and contain the microorganisms responsible for the water kefir fermentation. In this work, a water kefir fermentation process was followed as a function of time during 192 h to unravel the community dynamics, the species...

Low fermentation temperatures are of importance to food and beverage industries working with Saccharomyces cerevisiae Therefore, the identification of genes demonstrating a positive impact on fermentation kinetics is of significant interest. A set of 121 mapped F1 progeny, derived from a cross between haploid strains BY4716 (a derivative of the laboratory yeast S288C) and wine yeast RM11-1a, we...

During haymaking and ensilage, a significant loss of sugars occurs. The addition total mixed ratio (TMR) with liquid feed might provide promptly utilisable energy recover the nutrients lost during conservation. Interesting results were already obtained by including in TMR dairy cow. However, possibility to also utilize them Italian Mediterranean buffalo is not yet supported data. This study aim...

Gas production profiles were obtained from in vitro fermentation of stems of six genotypes of sorghum and millet grown at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India. The ranking of sorghum and millet genotypes by cumulative gas production was consistent throughout the 96-hour fermentation period. However, differences were proportionally greater during ...

Solid-state fermentation (SSF) of vinegar wastes saves environmental resources and helps to recover valuable material for lignocellulose purposes. The development of solid-state fermentation technology is very important for the production of cellulase and ultimately for utilization of natural cellulose. However, inadequate dissipation of heat generated by biological activities has prevented sol...

ARMSTRONG [1904] advanced the hypothesis that the specificity exhibited by yeast towards glucose, mannose and fructose was due to the existence of an enol form common to the three hexoses. Hopkins [1931] developed a modification of this hypothesis to show certain features of configuration common to ac-glucopyranose, ac-mannopyranose and fructofuranose using the configurations of Haworth. In the...

In the present work, a practical method for determination of the basic physicochemical parameters of beer real extract, alcohol and biomass concentration based on the amount of produced CO2 during the fermentation is investigated. The method was applied for determination of biomass concentration in immobilized preparations after its approbation with analytical data for beer fermentations with f...
