“…On comparing the structure of chitin with cellulose there exist acetylamine group at C2 position in case of chitin molecule whereas cellulose molecule has a hydroxyl group at this position [79]. The rigidity in the cell is due to the availability of peptidoglycan polymer which also prepares a thin layer on the cell wall of bacteria [80]. This long polymeric chain consists of many N-acetylmuramic and N-acetylglucosamine units which are linked together to form peptidoglycan polymer commonly known as glycan…”

Increased environmental pollution due to the organic wastes over the world is one of the most burning issues. These organic wastes lie under the category of biodegradable waste and can be effectively degraded from their complex compound into simple one by the action of microbes or other living organisms. Moreover, lignocellulosic biomass is a major part of the biodegradable waste and belongs to the group of renewable energy source, which can be very effective for bioenergy production. Biomasses are made up of different compounds such as cellulose, hemicelluloses, lignin and protein. Apart from these components, based on the structural analysis biomass also consist of bioactive substances such as carotenoids, flavonoids, lignin and antioxidants. This review explores a complete overview of the classification, component and the structure of the biomass. Moreover, it discusses how biomasses can play the key role of substrate in many sectors such as industrial bioenergy production including gaseous and liquid biofuels.

“…The rate of ethanol production is affected by several factors such as the acidity, temperature, and concentration of the substrate in the fermentation medium. It has been observed in some studies the possibility of bacterial growth within temperature range of 25-42°C (Farkas et al, 2020). Other studies have found that some strains grow at 38°C but did not grow at a temperature of 40°C, and fermentation can occur between temperatures of 30-36°C without any change in the ethanol yield (Deanda et al, 1996).…”

This review paper summarizes the best method for the utilization of agricultural wastes as raw material for the production of bioethanol. Agricultural wastes are rich in sugar and complex carbohydrates that makes it suitable source to carry out the fermentation process. Bioethanol is widely used in industries such as, chemical, pharmaceutical and food for various purposes especially as sterilizer. Carbohydrates are considered as the renewable sources and the primary material for the production of bioethanol. Microorganisms such as some species of yeasts and bacteria are capable to ferment carbohydrates and convert it into ethyl alcohol. However, the ability of these micro-organisms differs with respect to the production of ethanol and this research we study the possibility of producing bioethanol from the bacterium Zymomonas mobilis. One of the major industrial aspects of ethanol is the production of vinegar and there are several methods that could be utilized for its production from ethanol. Studies have reported that Zymomonas mobilis has 5-10 times more capability to produce bioethanol as compared with Saccharomyces cerevisiae. Therefore, this study has been done to highlight the possibilities of production of bioethanol from Zymomonas mobilis ARTICLE INFO

“…In paper manufacturing, chitinase addresses wastewater pollutants by breaking down chitin-containing substances, reducing effluent’s environmental impact. Chitinase facilitates and optimizes the deinking process for recycled paper by breaking down ink and impurities, enhancing efficiency and paper quality (Farkas et al 2020 ). Chitinase aids paper recycling by degrading coatings, adhesives, and fiber contaminants, elevating deinking efficiency and recycled paper quality.…”

Chitinases, enzymes that degrade chitin, have long been studied for their role in various biological processes. They play crucial roles in the moulting process of invertebrates, the digestion of chitinous food, and defense against chitin-bearing pathogens. Additionally, chitinases are involved in physiological functions in crustaceans, such as chitinous food digestion, moulting, and stress response. Moreover, chitinases are universally distributed in organisms from viruses to mammals and have diverse functions including tissue degradation and remodeling, nutrition uptake, pathogen invasion, and immune response regulation. The discovery of these diverse functions expands our understanding of the biological significance and potential applications of chitinases. However, recent research has shown that chitinases possess several other functions beyond just chitin degradation. Their potential as biopesticides, therapeutic agents, and tools for bioremediation underscores their significance in addressing global challenges. More importantly, we noted that they may be applied as bioweapons if ethical regulations regarding production, engineering and application are overlooked.
