Special issue from the 20th International Symposium on Alcohol Fuels (ISAF 2013): Alcohol fuels enabling sustainable development

Edited by Prof Willem H van Zyl

This special issue of Biotechnology for Biofuels features selected results and conclusions from the 20th International Symposium on Alcohol Fuels (ISAF 2013), which captures recent advances in conversion technologies for a variety of feedstocks and developments in microbes for raw starch and lignocellulose conversion. Many of these technologies and organismal developments could have applications in developing sustainable biofuel options for the future.

  1. Review

    Bioenergy and African transformation

    Among the world’s continents, Africa has the highest incidence of food insecurity and poverty and the highest rates of population growth. Yet Africa also has the most arable land, the lowest crop yields, and b...
