The global lignocellulosic biomass production is 181.5 billion tonnes per year 7. Agricultural residues, energy crops, forest residues, and cellulosic wastes are all excellent sources of lignocellulosic biomass. Lignocellulosic biomass is cellulose-based biomass that is both affordable and readily available for energy production.

However, because the output from this process is modest, process optimization and control are crucial for the sector's economic viability. Second-generation bioethanol development is now widely recognized as the most promising biofuels business, with many governments throughout the world taking an interest 6.One of the recommended techniques for the synthesis of these biofuels is the biochemical process, which uses enzymes and microorganisms to convert Lignocellulosic biomass into ethanol. Lignocellulosic biomass also contains polysaccharides that can be converted into simple fermentable sugars for the production of biofuels such as second-generation bioethanol 5.Unlike first-generation bioethanol, which is frequently made from sugar and amylaceous plants and raises ethical concerns owing to the use of foodstuffs, second-generation bioethanol is entirely made from plant components and does not compete with food production. It is made up largely of cellulose, hemicellulose, and lignin in varied quantities and comes in a variety of forms (agricultural leftovers, forest wastes, etc.). The most abundant renewable carbon source on the planet is lignocellulosic biomass (LCB) 4.

The European Commission has established a precedent in this area by committing to a 20 percent renewable energy target in total energy consumption by 2020, with biofuels expected to play a vital role in achieving this goal 3. Biofuels are one of these energy sources that is gaining popularity around the world 2 because they can be used in combustion engines. These greenhouse gases are to blame for the earth's global warming and the current climatic deregulation 1.As a result, in a global setting defined by the volatility of oil barrel prices and in the interests of environmental conservation, new and renewable energy is being produced. Furthermore, using fossil fuels increases greenhouse gas emissions, particularly carbon dioxide (CO 2). Because of the growth of emerging countries' transportation and manufacturing sectors, oil demand is expected to jump from 60% to 75% by 2030. Oil productioniscurrently the world's most important source of primary energy use.
