Acetic acid (167 mM) and lactic acid (548 mM) completely inhibited growth ofSaccharomyces cerevisiaeboth in minimal medium and in media which contained supplements, such as yeast extract, corn steep powder, or a mixture of amino acids. However, the y

Aims: The aim of this study was to evaluate interactions between Saccharomyces cerevisiae and selected strains of lactobacilli regarding cell viabilities, and production of organic acids and ethanol during fermentation. Methods and Results: Corn mash

Rye cultivars leading to high-viscosity extracts were easily mashed— even under very high gravity (VHG) conditions—when enzymes were added to reduce viscosity caused by pentosans. The enzymes were so effective that for the fuel alcohol industry,

Nine out of ten industrially important strains of Saccharomyces cerevisiae did not grow in minimal media under anaerobic conditions even when ergosterol and unsaturated fatty acids were provided. Anaerobiosis was maintained either by flushing the cul

The enzyme data presented here support the view that in Saccharomyces cerevisiae the flux of carbon through the glycolytic pathway is greater under nitrogen limiting than under nitrogen excess growth conditions. Enzyme data also suggest that conditio

The effects of osmoprotectants (such as glycine betaine and proline) and particulate materials on the fermentation of very high concentrations of glucose by the brewing strain Saccharomyces cerevisiae (uvarum) NCYC 1324 were studied. The yeast growin

Very high gravity (VHG) wheat mashes containing more than 300 g of dissolved solids per liter were prepared and fermented with active dry yeast at 20, 25, 30, and 35°C with and without yeast extract as nutrient supplement. At 20°C, mashes with 38%

We determined that paracrystalline protein surface arrays (S layers) protected gram-negative eubacteria from predation by Bdellovibrio bacteriovorus. Aquaspirillum serpens VHA and MW5 and Aquaspirillum sinuosum were resistant to predation by B. bacte

Growth rates determined by linear regression analysis revealed that Saccharomyces cerevisiae consistently grew more rapidly than Brettanomyces yeasts under a wide array of batch fermentative conditions, including acetic acid stress, in normal gravity

Normal-gravity (22 to 24 degrees Plato) wheat mashes were inoculated with five industrially important strains of lactobacilli at approximately 10(5), approximately 10(6), approximately 10(7), approximately 10(8), and approximately 10(9) CFU/ml in ord
