Lignocellulose wastes dominate our earth being considered as a serious cause for environmental pollution issues. However the lignocellulosic biomass can be converted to higher value-added products such as biofuel, enzymes etc. usually requiring a multi-step processing such as pretreatment, hydrolysis, fermentation etc. Cellulose is major polysaccharides in lignocellulosic biomass wastes being converted into simple sugars usually requiring synergistic action of multiple cellulolytic enzymes from different bacteria. Thermophiles act as a better source towards better lignocellulose biomass utilization for fermentation for various value-added product as well as biofuel production. Several researches were conducted on cellulolytic activity of thermophilic bacteria using various substrates. However the present study is mainly based on waste utilization containing cellulose as major component into different byproducts through cellulase enzymes from thermophiles which would enlighten the present market towards waste utilization ultimately combating the environmental pollution.
