Cellulosic bioethanol production from empty fruit bunches by locally produced cellulases

The global shortage of fossil fuels and environmental concerns to reduce pollution has resuscitated the interest in bioethanol production. Bioethanol is a promising alternative energy source that can be produced from renewable resources through hydrolysis and sugar fermentation processes. Its curren...
