Banerji and co-workers [14] found that dilute sulphuric
acid (below 30 g kg1) liberated more 5-carbon sugars than 6-
carbon sugars from sweet sorghum bagasse while Heredia-
Olea and co-workers [15] reported more 6-carbon sugars
liberated than 5-carbon sugars. Both authors from literature
made use of an enzymatic hydrolysis step after dilute acid
pretreatment to obtain the high sugar yields reported
