Sentence examples for of very high gravity from inspiring English sources
Most of the current processes of bioethanol production are based on the use of very high gravity (VHG) fermentations in which highly concentrated media (sugar-cane molasses, starch or grains) are used as substrates [ 1, 3].
However, the high sugar content of the very high gravity fermentation medium causes an increase in the osmotic pressure, which has a pessimistic effect on yeast cells, and the fermentations are rarely fast and complete.
