Ethanol and lactic acid production using sap squeezed from old oil palm trunks felled for replanting. J Biosci Bioeng. 2010 Sep110(3):322-5 p. 325 left column Table - link PubMed ID20547348

was grown on sap from the inner part of the trunk to produce lactic
acid. As shown in Fig. 3, glucose in the sap was readily converted to
lactic acid. Likewise in ethanol fermentation, no additional nutrients
were required and no growth inhibition was observed. Glucose, sucrose,
fructose, and galactose, at initial concentrations of 16.7 g/L, 1.28 g/L,
0.79 g/L, and 0.18 g/L, respectively, in the medium were completely
consumed after 72 h. The lactic acid yield was 89.9% of the theoretical
yield based on consumption of these 4 sugars.
||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. See table for sap content.
