Dual substrate fermentation strategy utilizing rice straw hydrolysate and crude glycerol for liquid biofuel production by Clostridium sporogenes NCIM 2918

Sequential biofuel production from seaweeds enhances the energy recovery: A case study for biodiesel and bioethanol production

“…Recently, sequential energy harvest from different biomass feedstocks was suggested to enhance the energy output. [15][16][17] However, much less attention is paid to investigate such approach in seaweeds for dual production of biodiesel and bioethanol. After lipid extraction, a valuable amount of residual biomass rich in carbohydrates is produced as a byproduct that can be further fermented into bioethanol.…”

Conversion of lignocellulosic biomass: Production of bioethanol and bioelectricity using wheat straw hydrolysate in electrochemical bioreactor

“…Thermal decomposition of untreated and pretreated WS was carried out using a DTG60H thermogravimeter (Shimadzu, Japan). The WS samples were placed under heating in an alumina crucible for temperatures ranging from 30 to 900 °C [ 27 ]. An increase in heating rate as 10 °C min −1 was maintained throughout under nitrogen atmosphere during the entire process.…”

Lignocellulosic Biomass – A Sustainable Feedstock for Acetone-Butanol-Ethanol Fermentation

“…Another cost-effective of ABE production was achieved by using rice straw as feedstock. The batch fermentation coupled with in situ product recovery with gas stripping of feedstock using Clostridium sporogenes NCIM 2918 result in high titer of alcohol production [35]. Another research aimed at the systematic use of both apple pomace soluble sugar and acidic or alkali hydrolyzed sugar for the development of ABE by anaerobic fermentation (Clostridium beijerinckii P260).…”

“…Therefore, renewable, and inexpensive feedstock such as lignocellulosic biomass open a new opportunity in biofuels production industries [20]. Table 2 [23,[32][33][34][35][36][37][38][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56] shows various potential feedstock that been utilized in ABE fermentation.…”
