Abstract	Enzymatic synthesis of flavours, fragrances and food additives compounds have great demand and market value. Benzyl butyrate is commercially important flavour and food additive compound having global use around 100 metric tons/year and widely used in various industrial sectors. However, industrial synthesis of food additive benzyl butyrate is carried out by conventional chemical process which demands for the green biobased sustainable synthetic process. The present work reports steapsin catalyzed synthesis of benzyl butyrate for the first time in supercritical carbon dioxide (Sc-CO

Abstract	Background and aim: The pandemic COVID-19 occurring due to novel emerging coronavirus-2019 (SARS-CoV-2) is severely affecting the worldwide public health, culture, economy and human social behaviour. Till date, there is no approved medicine/treatment to cure COVID-19, whereas, vaccine development efforts are going on high priority. This review aimed to provide an overview of prior art, recent advances, vaccine designing strategies, current scenario, opportunities and challenges related to development of coronavirus vaccine. Method: A literature survey was conducted using Scopus, PubMed and Google Scholar with the search key as: coronavirus vaccine, SARS vaccine, MERS vaccine and COVID-19 vaccine. Articles related to above search query were retrieved, sorted, analyzed and developed into an easy-to-understand review. Results: The genome phylogenetic analysis suggested that genomic sequence of SARS-CoV-2 is almost 80% similar to that of SARS-CoV, further both these viruses bind to same host cell receptor ACE-2. Hence it is expected that, previously available literature data about coronavirus vaccine designing may play crucial role in development of rapid vaccine against COVID-19. In view of this, the present review discuss (i) existing information (from 2003 to present) about the type of vaccine, antigen, immunogenic response, animal model, route of administration, adjuvants and current scenario for designing of coronavirus vaccine (ii) potential factors and challenges related to rapid development of COVID-19 vaccine. Conclusion: In conclusion, we discuss possible clues/ target sites for designing of vaccine against SARS-CoV-2 virus based on prior-art.

Abstract	Levulinate compounds are considered as a potential energy chemical and bio-lubricant of the present century due to extraordinary application in fuel blending which improves the performance and efficiency of fuel and engine. The traditional industrial synthesis of levulinate compounds involves the use of hazardous reagents/chemicals and harsh reaction temperature conditions which are considered as non-green methodologies that violate the green and sustainable chemistry principles. The recent literature survey suggested that enzyme (lipase) catalyzed synthesis of levulinate compounds may be a competent solution over the present traditional synthesis. However, there is need of extensive research efforts and reviewing of recent advances in this field to get the proficient synthesis of levulinates through enzyme catalysis. In view of this, the present review article highlights the current state of the art in this field along with major challenges for the proficient enzyme catalyzed scale-up production of levulinate compounds.

Abstract	The present work deals with the synthesis of lab-made carboxymethyl cellulose (CMC) and chitosan (CHI) based co-polymer cross-linked with glutaraldehyde (GLU) which is used as immobilization matrix for the immobilization of Candida rugosa (CRL) lipase (CMC:CHI:GLU:CRL). This immobilized biocatalyst was subjected to characterization such as lipase-activity, kinetic-parameters, water-content, surface-texture, stability and half-life time etc. Effect of various ultrasound parameters (power, frequency, duty cycle, exposure time) on lipase activity is also tested which indicated that, developed biocatalyst has significant activity-stability and half-life-time in ultrasonicated medium. Further, this biocatalyst was applied to synthesize biomass-derived furfuryl derivative which offering excellent conversion of 99 % of bio-based furfuryl ester. The synthetic protocol is optimized in detail (with twelve reaction parameters) under ultrasonicated medium. Recyclability study offered 68 % conversion of the furfuryl ester after sixth reuse. Moreover, the developed protocol is well extended to synthesize various commercially important compounds. Besides this, we investigated thermodynamic parameters (ΔG, ΔH, ΔS*) which demonstrating more feasibility of biocatalytic synthesis in ultrasonicated medium than conventional medium. Finally, green metrics evaluation parameters (E-factor, carbon-efficiency and mass-intensity) are studied which indicating efficient synergetic role of immobilized CMC:CHI:GLU:CRL lipase biocatalysis and ultrasonication in green and sustainable synthesis.

Abstract	In the present work, we have investigated biochemical thermo-kinetic stability of lipases immobilized on a biocompatible polymeric material. Immobilization of lipase Candida rugosa (CRL) was carried out on biocompatible blend of poly vinyl alcohol (PVA) and chitosan (CHY) support via entrapment and glutardehyde (Glu) cross-linking method to produce PVA:CHY:CRL and PVA:CHY:Glu:CRL as robust biocatalyst. These immobilized lipases were characterized by various physico-biochemical characterization techniques. Later on, thermal and solvent stability of polymer immobilized lipase was determined in term of half-life time (t

Abstract	The utilisation of non-feed lignocellulosic biomass as a source of renewable bio-energy and synthesis of fine chemical products is necessary for the sustainable development. The methods for the dissolution of lignocellulosic biomass in conventional solvents are complex and tedious due to the complex chemical ultra-structure of biomass. In view of this, recent developments for the use of ionic liquid solvent (IL) has received great attention, as ILs can solubilise such complex biomass and thus provides industrial scale-up potential. In this review, we have discussed the state-of-art for the dissolution of lignocellulosic material in representative ILs. Furthermore, various process parameters and their influence for biomass dissolution were reviewed. In addition to this, overview of challenges and opportunities related to this interesting area is presented.

Abstract	Levulinate esters are unique potential value added energy-chemicals which has significantly attracted remarkable attention of global researchers due to its potential importance as a fuel-blending chemical. Conversely, competent synthesis of levulinate compounds is in initial phase of research which mostly involves the challenging catalytic synthesis. The existing literature showed that, the role of acid-functionalized catalyst is very important for the synthesis of levulinate esters whereas, various kinds of the catalyst are widely used in last few years to synthesize these value added chemicals. Moreover, applications of levulinate compounds as energy products are in emergent phase which requisites the extensive research efforts to improve engine performance and process efficiency. Looking to this view, the present article execute critical evaluation of progressing research linked to (i) potential applications of the levulinate compounds, (ii) market scenario of levulinate synthesis, (iii) different catalytic pathways of levulinate synthesis (iv) mechanistic approach to synthesize levulinate (v) use of various catalysts to obtain levulinates (vi) fuel blending properties of levulinates and (vii) advantages of levulinates as a fuel blender. Moreover, the present article also summarizes the future opportunities and challenges associated with the development of representative levulinate synthesis biorefinary.

Abstract	The present work deals with the designing of biocompatible hybrid blend of cellulosic copolymers made of hydroxypropyl methylcellulose (HMC) and chitosan (CHI) for immobilization of Rhizomucor miehei lipase (RML), in order to construct the robust biocatalytic system to synthesize industrially important dodecanoate compounds (fatty acid esters). The present biocatalyst HMC:CHI:RML was characterized in detail by various physical and biochemical methods and subsequently applied for the synthesis of fatty acid esters. The protocol was optimized in detail with kinetic parameters which provides excellent % conversion, and further we have synthesized fifteen industrially important compounds which have wide potential for commercial applications. The immobilized lipase HMC:CHI:RML offered four- to eightfold higher conversion and biocatalytic activity as compared to crude lipase. Besides this, recyclability study was also performed to assess economic and industrial viability.
