“…Initial waste is generated just after paper mill. This waste contains paper fibers (cellulose and its derivatives) and many other substances: polyethylene, polypropylene, polystyrene, polyethylene terephthalate (PET), fluorocarbon-based polymers, polyvinyl chloride, polyamide, fillers and binders, surfactants, adhesives, bleaches, traces of heavy metals and other [4,5,6,7]. Also, this waste contains textiles and metal inclusions.…”

“…However, each process can be simultaneously carried out, which is referred to simultaneous saccharification and fermentation (SSF) process. SSF process has been regarded as the major option due to high overall yields and process integration [6]. SSF process is favorable because it requires low energy consumption and short process time.…”

Ethanol productions were performed by separate hydrolysis and fermentation (SHF) and simultaneous saccharification and fermentation (SSF) processes using seaweed, Enteromorpha intestinalis (sea lettuce). Pretreatment conditions were optimized by the performing thermal acid hydrolysis and enzymatic hydrolysis for the increase of ethanol yield. The pretreatment by thermal acid hydrolysis was carried out with different sulfuric acid concentrations in the range of 25 mM to 75 mM H 2 SO 4 , pretreatment time from 30 to 90 minutes and solid contents of seaweed powder in the range of 101 6% (w/v). Optimal pretreatment conditions were determined as 75 mM H 2 SO 4 and 13% (w/v) slurry at 121 o C for 60 min. For the further saccharification, enzymatic hydrolysis was performed by the addition of commercial enzymes, Celluclast 1.5 L and Viscozyme L, after the neutralization. A maximum reducing sugar concentration of 40.4 g/L was obtained with 73% of theoretical yield from total carbohydrate. The ethanol concentration of 8.6 g/L of SHF process and 7.6 g/L of SSF process were obtained by the yeast, Saccharomyces cerevisiae KCTC 1126, with the inoculation cell density of 0.2 g dcw/L.

Lignocellulose-a major component of biomass available on earth is a renewable and abundantly available with great potential for bioconversion to value-added bio-products. The review aims at physio-chemical features of lignocellulosic biomass and composition of different lignocellulosic materials. This work is an overview about the conversion of lignocellulosic biomass into bio-energy products such as bio-ethanol, 1-butanol, bio-methane, bio-hydrogen, organic acids including citric acid, succinic acid and lactic acid, microbial polysaccharides, single cell protein and xylitol. The biotechnological aspect of bio-transformation of lignocelluloses research and its future prospects are also discussed.
