Title: Prebiotics formation by using sugarcane bagasse: A novel approach
Prebiotics are compounds in food that induce the growth or activity of beneficial microorganisms such as bacteria and fungi. The most common example is in the gastrointestinal tract, where prebiotics can alter the composition of organisms in the gut microbiome. Prebiotics are a source of food for your gut's healthy bacteria. The premise behind prebiotics is therefore to stimulate certain indigenous bacteria resident in the gut rather than introducing exogenous species as is the case with probiotics. Ingesting a diet containing non-digestible carbohydrates that are selectively fermented by indigenous beneficial bacteria is the prebiotic principle. Oligosaccharides are sugars consisting of approximately two and 20 saccharide units, i.e. they are short-chain polysaccharides which can be used as prebiotics. The major prebiotic oligos on the market are inulin, fructo oligosaccharides, and galacto-oligosaccharides. Apart from those, which occur naturally in fruits and vegetables, and are extractable, others can be commercially produced through the hydrolysis of polysaccharides (e.g. dietary fibers, starch) or through enzymatic generation. Plant biomass such as sugarcane bagasse can be enzymatically saccharified for the production of oligosaccharides. Currently, a major proportion of bagasse is burned to produce energy, which results in environmental problems and also incurs loss of this valuable bio-resource. Therefore, the utilization of sugarcane bagasse will greatly contribute to the socio-economic development in Pakistan by utilizing regional agricultural resources as an environmentally friendly approach to add value to the traditional products. The utilization of bagasse for biorefinery purposes will provide a path to develop technologically advanced industries in Pakistan.
