The fermentative production of biobutanol was investigated via series of steps, viz. characterization, drying, acid hydrolysis, detoxification, and fermentation. Press mud contains an adequate amount of cellulose (22.3%) and hemicellulose (21.67%) on dry basis, and hence, it can be utilized for further acetone-butanol-ethanol (ABE) production. Drying experiments were conducted in the temperature range of 60–120 °C to circumvent microbial spoilage and enhance storability of press mud. Furthermore, acidic pretreatment variables, viz. sulfuric acid concentration, solid to liquid ratio, and time, were optimized using response surface methodology. The corresponding values were found to be 1.5% (v/v), 1:5 g/mL, and 15 min, respectively. In addition, detoxification studies were also conducted using activated charcoal, which removed almost 93–97% phenolics and around 98% furans, which are toxic to microorganisms during fermentation. Finally, the batch fermentation of detoxified press mud slurry (the sample dried at 100 °C and pretreated) using Clostridium acetobutylicum NRRL B-527 resulted in a higher butanol production of 4.43 g/L with a total ABE of 6.69 g/L. © 2017 Springer Science+Business Media New York Author keywords</p>10aAcetone10aAcetone butanol ethanols10aAcidic pre treatments10aAgriculture10aBiobutanol10acellulose10aClostridium acetobutylicum10aDetoxification10aDrying10aDrying Fermentation10aFermentationSpoilage10aFermentative production10aPre-treatment10aPress mud10aPress mud Pretreatment10aResponse surface methodology10aSugar industry10aSulfur determination1 aNimbalkar, Pranhita, R.1 aKhedkar, Manisha, A.1 aGaikwad, S., G.1 aChavan, Pramod, V.1 aBankar, Sandip, B.  uhttps://library.ncl.res.in/content/new-insight-sugarcane-industry-waste-utilization-press-mud-cleaner-biobutanol-production
