After publication, the authors noticed an accidental error existing in this article [1]. In Table 1, they mistakenly listed the Ethanol yield of sweet sorghum stem as “6.25 g ethanol/100 g drystalk”. This information should be corrected as “6.25 g ethanol/100 g fresh stalk” (Table 1). This change will in no manner affect the outcome/interpretation of the experiments as described in the original publication. The authors apologize for any inconvenience caused.
