A massive amount of waste is generated globally from agriculture sector annually that offers potential feedstock for biorefineries. Undoubtedly α-amylase has become the backbone of starch-based industries. It is a crucial amylolytic enzyme possessing versatile applications. An expensive synthetic substrate that is non-eco-friendly and toxic is not...

The growing consumption of fossil fuels like coal, petroleum, and diesel releases greenhouse gases that ultimately deteriorate the air quality. Moreover, fossil fuels pose serious threats like global warming, ocean acidification, unusual climate change and ecosystem fluctuation to the environment and human health. Biofuel is a feasible and sustaina...

The demand for an alternative source of energy is an imperative requirement of the current time. Second-generation biofuel (bioethanol) is capable of overcoming the problem of energy crises soon. Bioethanol production from agricultural by-products is an effective and sustainable approach. Bioethanol from agro-waste residues fulfil the energy demand...

India and several other countries are facing the biggest threat to survival due to a novel pandemic called Coronavirus and diseases (COVID-19) which was originated from Wuhan in China in the year 2019. This coronavirus belongs to the group of respiratory viruses (SARS-CoV-2). Its mode of transmission is through respiratory droplets released from th...

α-Amylases are the oldest and versatile starch hydrolysing enzymes which can replace chemical hydrolysis of starch in industries. It cleaves the α-(1,4)-D-glucosidic linkage of starch and other related polysaccharides to yield simple sugars like glucose, maltose and limit dextrin. α-Amylase covers about 30% shares of the total enzyme market. On acc...

Infectious diseases produced by bacteria are an urgent healthcare concern worldwide. Several infections in humans are caused by bacterial agents such as Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, and Staphylococcus aureus. The current development of resistance to antibiotics and accompanying toxicity issues is ca...

α-Amylase is the most significant glycoside hydrolase having applications in various industries. It cleaves the α,1–4 glucosidic linkages of polysaccharides like starch, glycogen to yield a small polymer of glucose in α-anomeric configuration. α-Amylase is produced by all the three domains of life but microorganisms are preferred sources for indust...

The world is gaining a lot of interest in the production of bioethanol from various biobased, agricultural waste sources in order to reduce net carbon dioxide emissions and lower the global dependence on fossil fuels. Lignocellulosic materials were a good choice as a feedstock for ethanol production considering their incredible accessibility and th...

The application of principles of biology and engineering to create usable and economically viable products is called engineering. This technology has been used in fungi to get the valuable products through fungal bioengineering. The fungi are useful in terms of the production of commercial and industrial products as well as biofuels such as bioetha...

Processing (milling, oil extraction) of agricultural products result in accumulation of massive amount of agro-waste residues. A sustainable alternative technique is required to utilize those agro-waste residues through biotechnology to convert them into useful products. α-Amylase is an enzyme of glycoside hydrolases family which hydrolyzes the α-D...

Chhattisgarh is known as “rice bowl of India” due to enormous production of rice. Rice is the major ingredient of the ethnic fermented food and beverages of Chhattisgarh. Apart from rice, traditional dishes are also made from wheat, barley, and different lentils. Fermentation process has an impact on food’s aroma, flavor, texture, and nutritional c...

Water is the most fundamental natural resource found on the Earth which is equally important to all living organisms. About 70% of the Earth surface is secured with water. The endurance and nature of human life depend upon the accessibility of freshwater. Natural water quality is deteriorating by utilizing various contaminants such as physical, che...

The objective of the experiment is to study the production of bioethanol from rice bran from Bacillus cereus strain McR 3. This study was designed to evaluate the role of some fermentation parameters such as nutrients and metal ions supplementation which affects the production process. Bioethanol has emerged as the most suitable renewable alternati...

Bioethanol more appropriately termed as alternative transportation fuel play a key role in reducing the world dependence on fossil fuels. Bio-ethanol is an oxygenated fuel that contains 35% oxygen which reduces particulate and nitrogen oxides (NOx) emissions from combustion. Henceforth using bioethanol blended fuel for automobiles can significantly...

The most valuable bioenergy source today is bioethanol, which is produced by fermentation of sugar, starch or cellulose containing biomass using various microorganisms. Bioethanol represents closed carbon dioxide cycle, after burning of bioethanol, the released carbon dioxide is recycled back into plant material because plants use carbon dioxide to...

The potential environmental benefits that can be obtained from replacing petroleum fuels with biofuels derived from renewable biomass sources are the main driving forces for promoting the production and use of biofuels. Due to depletion of fossil fuels, ethanol, which can be obtained via the bioconversion of renewable feedstock, is widely regarded...

Bioethanol is regarded as one of the most promising biofuel from renewable sources. The development of ethanol production from lignocellulosic material is thus considered as the second-generation biofuel technology. Lignocelluloses account for the majority of the total biomass present in the world. To initiate the production of industrially importa...
