Reference Kosugi A, Tanaka R, Magara K, Murata Y, Arai T, Sulaiman O, Hashim R, Hamid ZA, Yahya MK, Yusof MN, Ibrahim WA, Mori Y. Ethanol and lactic acid production using sap squeezed from old oil palm trunks felled for replanting. J Biosci Bioeng. 2010 Sep110(3):322-5 tables 1-6 pp.324-5PubMed ID20547348
Method Moisture content was determined by drying at 105 °C for 48 h. Sugars contained in the sap were determined by high performance anion-exchange chromatography using CarboPac PA (Dionex Corporation, Sunnyvale, CA, USA) with pulsed amperometric detection (HPAEC-PAD). Amino acids were analyzed by an amino acid analyzer (Hitachi L-8900). Organic acids: high performance ion exchange chromatography. Mineral analyses were carried out by inductively coupled plasma atomic emission spectroscopy with VistaMP-X(Varian, Inc.). Thiamine (8) and riboflavin (9) were analyzed by HPLC with fluorescence detection. Ascorbic acid was analyzed by HPLC with a UV-Vis variable wavelength detector. Vitamin B6, pantothenic acid, niacin, inositol, folic acid and biotin were measured by microbiological methods.
Comments In order to utilize the old palm trunks felled for replanting, especially the inner part, researchers attempted to produce bioethanol and lactic acid, the material for bio-plastics, from felled trunks.
