Cellulose undergoes hydrolysis utilizing chemicals to deliver glucose, which might be utilized for the production of ethanol, organic acids, and various chemicals. Cellulases are a collection of hydrolytic catalysts that can hydrolyze the most plentiful natural polymer for example cellulose into smaller sugar components including glucose subunits. Cellulase is overpriced and contributes simply half to the general expense of hydrolysis because of the low explicit activity. This enzyme has enormous potential in industries and its use in food, beverages, textile, laundry, paper, and mash industries, and so forth. Consequently, there has been a lot of examination focused on new microorganisms producing cellulose enzymes with higher specific activities and greater efficiency. Currently, work is pointed toward screening and disconnecting cellulolytic growths from the marine samples gathered from the Bay of Bengal, Puri coast, Odisha. All out 7 fungi were isolated from these dirt examples, out of which 2 fungi were portraying the extensive cellulase activity. The fungal isolate, for example, MWF-1 andMSF-6 isolated from water silt respectively were recognized to show the most extreme zone of hydrolysis of carboxy-methyl cellulose. The cellulase activity was assayed by Carboxymethylcellulose "CMCase" (endoglucanase) measure.

Generally, a gene which is inserted directly into a cell does not operate independently. Instead, the transmission of the gene is genetically modified by a biological messenger called a vector, consists of a transgene and a large DNA sequence as a backbone. Since they can deliver the new gene by infecting the cell, such viruses are also used as vectors. The adenovirus is a non-enveloped virus that can be tailored to transfer DNA to target cells, and it has sparked a lot of interest in the field, particularly in clinical trial therapy techniques. For the new age production of COVID-19 vaccine, development of different mammalian cell lines like HEK293 (most reliable growth and prosperity for transfection) and recombinant adenoviral vectors have become the first priority for biopharmaceutical giants and globally approved vaccine manufacturers to scale up their vaccine production. Adenoviruses have an icosahedral shape, with a protein coat encasing the viral double-stranded DNA genome. Because the adenovirus genome is relatively small, it's a good candidate for insertion of foreign DNA. The adenovirus E1A gene is deleted, and the virus loses its capacity to replicate. This ability can be restored during cell culture propagation by employing cells that produce the E1A protein, for example. Hence, in this mini research, I have shared an overview of the propagation of adenoviral vectors, i.e. recombinant adenovirus SARS CoV-2 vector in HEK-293 cell suspension culture.

Marine fish are well-known for being a high-quality protein source having high concentration of essential amino acids. It has high concentration of mono unsaturated and poly unsaturated fatty acids, which may aid in the optimization of lipid profiles and the reduction of the risk of coronary heart disease (CHD). The goal of this study was to estimate the nutritional and biochemical status of raw sea fish Pampus argenteus after 30 days of frozen storage at -200C with 15-day intervals. Nutrient study showed a decrease in protein and lipid content. The changes of hydrogen peroxide and oxidized lipid products were estimated in the muscle tissue during fresh and storage condition. Results indicate that during storage the oxidative stress increased. An antioxidant enzyme (superoxide dismutase, smutase, catalase, glutathione peroxidase) measurement was determined. The increased amount of oxidative stress during fish storage is shown by the differential activity of antioxidant enzymes. The amount of protein in fish varies slightly between species and even within species. Fish is high in protein, vitamins, minerals, and omega-3 fatty acids, which are essential for brain development (Spencer et al., 1971; Jacylin et al., 2010). A well-balanced diet consists variety of fish that can help in children's growth and development as well as their heart health (Jinadasa, 2014).

Fish account fifty percent of entire vertebrates present on the planet. They can be found practically in every possible aquatic habitats; from the 39,900 species of vertebrates, 21,723 are fishes with 8,411 being freshwater species while 11,650 being marine. There are about 2,500 species of fishes are present in India out of which 930 of them living in freshwater and 1,570 in the ocean. So, in the present study, we collected three fresh water fish’s i.e. Clarias batrachus, Cirrhinus reba, Channa punctatus from the river Mahanadi. Information on the comparative account of antioxidant protection in these fishes from Mahanadi river is relatively scanty. As a result, the purpose of this research was to explore the proximate composition of the three popularly used Fresh water fish species from the river Mahanadi. The result of the present study involved an integrated study of muscle tissue of C. batrachus, C. reba and C. punctatus which shows alteration in lipid per oxidation, hydrogen peroxide and antioxidant defence system. Results of this investigation suggest that C. reba were considered as a highly proteinaceous fish for which they are widely used in food industries. Still, more research work is required to explore the nutritional value of various types of fish muscles and their products.

Coronavirus spreads from human to human or human to animal via airborne droplets. Coronavirus penetrates human cells via the membrane ACE-2 exopeptidase receptor. There are no specific anti-virus medi- cations or vaccinations available to treat this sudden and fatal sickness during COVID-19 except vaccination. Still, it will take months, if not years, to create these antiviral drug therapies to combat against this pandemic. Phytochemicals have a huge significant anti-inflammatory activity, which can reduce lung injury like major inflammation occurring in the lungs of a covid19 patient. To improve the symptoms of COVID-19 infected patients, supportive care and non-specific treatment are now required. As an alternate measure, fast application of herbal medicine or phyto-chemicals can help with this specific indication. Phytochemicals are a potent class of compounds generated from plants that have less adverse effects due to the lack of additives, preservatives, and excipients. The new COVID19 variants are much dangerous than the early ones which is a major drawback for the early developed vaccines. As a result, the focus of this review will be on certain phytochemicals and their mechanism of action that may be used to manage and prevent SARS-CoV-2 and its major variants emerging nowadays.

Basic human biology is dealt with by mRNA, which creates instructions for making proteins that may aid in the fight against infectious illnesses using our bodies' own mechanisms. mRNA therapies are neither tiny compounds nor huge biological such as recombinant proteins or monoclonal antibodies. These are a series of instructions that assist our cells' machinery in producing proteins that protect us against a certain virus. Our bodies would be unable to perform their activities if mRNA was not introduced. mRNA, or messenger ribonucleic acid, is an important component of the living world, especially in the process of protein synthesis. mRNA is a single-stranded molecule that transmits genetic instructions from a cell's nucleus DNA to the ribosomes, which are the cell's protein-making machinery. The synthesis of an RNA copy from the coded sequence of DNA leads in the production of a particular protein. This copy of mRNA moves from the nucleus of the cell to the cytoplasm, where ribosomes reside. Ribosomes are a sort of sophisticated machinery organelle that aids and begins protein synthesis in cells. Ribosomes ‘read' the mRNA sequence and follow the instructions, progressively adding on various needed amino acids to make the intended protein during the translation process. The protein is subsequently expressed by the cell, and it goes on to execute its role in the cell or in the body. The use of mRNA as a medication offers up a whole new universe of possibilities in terms of illness treatment and prevention. This review contributes to the growing body of knowledge in the field of mRNA therapeutic delivery and the identification of appropriate antigens for mRNA target locations. Two major mRNA vaccines for protection against SARS-CoV-2 have recently been developed and approved for use in the general population by international health authorities. They've been demonstrated to defend against the SARS-CoV-2 virus, which is still active and evolving. This will draw attention to a variety of mRNA vaccines now being evaluated for infectious diseases in clinical studies. mRNA vaccines offer a number of advantages, including speedy design, fabrication, manufacturing, and administration, and they hold a lot of potential for future use against a wide range of diseases.
