• Some of the major challenges in bioethanol production are the recalcitrant lignin, high cost of holocellulase and inadequate or non-utilization of pentose fraction during fermentation that has grave impediment in attaining a cost effective and viable process. (omicsonline.org)
  • The mutants showed little variation in ethanol productivity when grown on glucose or galactose, yet diversity was revealed during growth on xylulose, a rare pentose not widely available in nature. (g3journal.org)
  • Pentose sugar was found in 1893 by Albrecht Kossel who was the first person to recognise that nucleic acids (called nuclein at the time) contained a carbohydrate . (factbites.com)
  • Each individual nucleotide is further made up a pentose sugar , nitrogenous base and a phosphoric acid. (factbites.com)
  • The pentose sugar component is the backbone of the whole nucleotide unit. (factbites.com)
  • It is to this pentose sugar that other the nitrogenous base and phosphoric acid attaches to. (factbites.com)
