The impact of moist corn grain preservation on the ethanol yield by simultaneous saccharification and fermentation, and on volatile by-products
bioethanol chemical preservation SSF volatile compounds
2014/10/11
We assessed the composition of volatile by-products in raw spirits obtained from moist corn fermentation. The average moisture value of the researched samples was 35.4%. A comparative research was con...
Succinic Acid Synthesis by Ethanol-Grown Yeasts
succinic acid Candida catenulata Candida zeylanoides ethanol
2009/8/10
The synthesis of succinic acid in ethanol-containing media has been tested in 32 yeasts of different genera (Debaryomyces, Candida, Pichia, Saccharomyces, Torulopsis). The capability of succinic acid ...
Ethanol Sensor Using Two Chloride Ion-Selective Polymeric Membrane Electrodes
ethanol chloride ion-selective polymeric membrane electrode plasticizer
2009/7/7
An ethanol sensor using two chloride ion-selective polymeric membrane electrodes (Cl-ISEs) was developed. Two different polymeric membranes were used, one with o-nitro-phenyloctyl ether (NPOE) and the...
