Hydrogen production by cultures of C. saccharolyticus and T. neapolitana grown on pure sugars and Miscanthus hydrolysate. Growth (squares) and hydrogen production (circles) in cultures of C. saccharolyticus (a) and T. neapolitana (b) grown on a glucose/xylose (7:3, w w-1) mixture (open symbols) or Miscanthus hydrolysate (filled symbols). The monosaccharide concentration was 14 g l-1.
