Thermo-acidophillic biohydrogen production from rice bran de-oiled wastewater by Selectively enriched mixed culture
RESEARCH ON THE CHANGE OF 2-AP AND OTHER VOLATILE COMPOUNDS IN PROCESSING BUN FROM RICE
... Volatile compounds in Chucheong rice from Korea recorded by GC-FID showed that it has no peak 2-AP at the Rt 9.498 minute 3.3. Identification of 2-AP in OM rice from Cuulong Rice Research Institute, ... Bích Liễu 3.2. Identification of 2-AP in Korea rice varieties By SPME coupling with GC-FID, rice samples from Korea were extracted and analyzed by the same conditions as described above. The ... 2-AP as standard. Rice materials include two varieties from Vietnam, OM 6162, Khao Dawk Mali (KDM) and two varieties from Korea, Chuch eong variety (milled rice) , and Black rice (mixture of several...

Characteristics of hydrogen production from food waste and waste activated sludge
... specific hydrogen production potential (mL/g VS) was obtained by dividing P by the substrate weight (g VS), while the specific hydrogen production rate was calculated by dividing R m by the inoculum ... Effect of pH on hydrogen production from glucose by a mixed culture, Bioresource Technol., 82, 87-93. Hallenbeck, P. C. and Benemann, J. R., 2002. Biological hydrogen production; fundamentals ... were related with hydrogen production in this study (Payot et al., 1998; Yokoi et al., 1998). H 2 /VFA production was followed by alcohols production. In normal batch culture, Clostridium sp. form...

INFLUENCE OF NITROGEN, ACETATE AND PROPIONATE ON HYDROGEN PRODUCTION FROM PINEAPPLE WASTE EXTRACT BY Rhodospirillum rubrum
... successful hydrogen production from sucrose and sugar derivatives. Huss et al.(2004) reported that the hydrogen production from sucrose and pulped sugar beet by anaerobic digester sludge from a sewage ... production by the seed sludge mixed culture from glucose was 64% with a yield of 2.1 ± 0.1 mol H 2 /mol glucose. In addition, sugar substance such as pure sucrose (Sung et al., 2002), sugar wastewater ... inhibited hydrogen production by photosynthetic bacteria. These microorganisms produce hydrogen by the catalytic activity of nitrogenase, which is inhibited by nitrogen (at hydrogen production only)....
