WILD YEAST IN DRAUGHT BEER: II. STUDIES ON YEASTS ISOLATED FROM DRAUGHT BEER

Draught Animal Power

Draught animals and welfare.

In fifty developing countries, which contain half of the total human population of the world, there is a heavy dependence on draught animals as an energy source. These animals are used for agriculture operations in 52% of cultivated areas of the world, as well as for hauling 25 million carts. This situation is likely to continue for at least another fifty years. The work performed annually by t...

Nutritional implications of work in draught animals.

Draught animals have not been used to any great extent in agriculture in the developed countries since the introduction of tractor power in the 1930s and the rapid expansion of agricultural mechanization over the succeeding decades. In the Third World, however, draught-animal power continues to make an important contribution to rural and urban economies. In fields that tractors cannot reach, su...

Domestication and Divergence of Saccharomyces cerevisiae Beer Yeasts

Whereas domestication of livestock, pets, and crops is well documented, it is still unclear to what extent microbes associated with the production of food have also undergone human selection and where the plethora of industrial strains originates from. Here, we present the genomes and phenomes of 157 industrial Saccharomyces cerevisiae yeasts. Our analyses reveal that today's industrial yeasts ...

The wine and beer yeast Dekkera bruxellensis

Recently, the non-conventional yeast Dekkera bruxellensis has been gaining more and more attention in the food industry and academic research. This yeast species is a distant relative of Saccharomyces cerevisiae and is especially known for two important characteristics: on the one hand, it is considered to be one of the main spoilage organisms in the wine and bioethanol industry; on the other h...
