Fermentation Products of Cellulose

IN WORKING on the products resulting from the anaerobic decomposition of biologic waste material, the writers, with others (1), have observed that the reactions, which are brought about by bacteria, cause the formation of considerable amounts of gas. This gas is principally methane and carbon dioxide, with small amounts (3-5 per cent) of hydrogen and nitrogen, the latter probably from solution ...

Third Generation Biofuels via Direct Cellulose Fermentation

Consolidated bioprocessing (CBP) is a system in which cellulase production, substrate hydrolysis, and fermentation are accomplished in a single process step by cellulolytic microorganisms. CBP offers the potential for lower biofuel production costs due to simpler feedstock processing, lower energy inputs, and higher conversion efficiencies than separate hydrolysis and fermentation processes, an...

Natural Products as Manipulators of Rumen Fermentation

There is increasing interest in exploiting natural products as feed additives to solve problems in animal nutrition and livestock production. Essential oils and saponins are two types of plant secondary compounds that hold promise as natural feed additives for ruminants. This paper describes recent advances in research into these additives. The research has generally concentrated on protein met...

Fermentation Products of Certain Mannitol- Forming Bacteria.*

The formation of mannitol in fermenting mixtures of plant, origin is now known to be due to a group of bacteria which act upon fructose and reduce this sugar to its corresponding alcohol. Mannitol-forming bacteria have been found in wine, sauerkraut, silage, canned goods, yeast, and cereal infusions. In some of t,hcse products such as sauerkraut and silage, their presence is not, objectionable,...
