Abstract
Chondroitin sulfate (CS) is a glycosaminoglycan with a growing variety of applications. CS can be produced from microbial fermentation of native or engineered strains. Synthetic biology tools are being used to improve CS yields in different hosts. Integrated polymerization and sulfation can generate cost-effective CS.
Chondroitin sulfate (CS) is a glycosaminoglycan with a broad range of applications being a popular dietary supplement for osteoarthritis. Usually, CS is extracted from animal sources. However, the known risks of animal products use have been driving the search for alternative methods and sources to obtain this compound. Several pathogenic bacteria naturally produce chondroitin-like polysaccharides through well-known pathways and, therefore, have been the basis for numerous studies that aim to produce chondroitin using non-pathogenic hosts. However, the yields obtained are not enough to meet the high demand for this glycosaminoglycan. Metabolic engineering strategies have been used to construct improved heterologous hosts. The identification of metabolic bottlenecks and regulation points, and the screening for efficient enzymes are key points for constructing microbial cell factories with improved chondroitin yields to achieve industrial CS production. The recent advances on enzymatic and microbial strategies to produce non-animal chondroitin are herein reviewed. Challenges and prospects for future research are also discussed.

Abstract
COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has threatened the whole world affecting almost 243 million people globally. Originating from China, it has now spread worldwide with USA and India being the two most affected countries which emphasizes the immense potential of the coronaviruses to cause severity in the human population. This study validates the efficacy of some marine antiviral agents to target the viral main protease (Mpro) of SARS-CoV-2 by in silico studies. A total of 14 marine-derived antiviral agents were screened from several databases including PubChem and DrugBank and docked against the crystallised 3D structure of SARS-CoV-2 Mpro. MD simulation of the top two ligands was carried out for 100 ns to validate the protein-ligand stability. Later, their physicochemical, pharmacokinetics, and drug-likeness properties were evaluated and toxicity prediction was performed using eMOLTOX webtool. We found that all the 14 compounds are acting as a good target for Mpro. Among them, avarol and AcDa-1 procured the best docking results with the estimated docking score of −8.05 and −7.74 kcal/mol respectively. MD simulation revealed good conformational stability. The docked conformation was visualised and subsequent ligand-amino acid interactions were analysed. Avarol revealed good pharmacokinetic properties with oral bioavailability. The overall finding suggested that these marine compounds may have the potential to be used for the treatment of COVID-19 to tackle this pandemic.

Abstract
The COVID-19 pandemic has made it essential to explore alternative antiviral materials. Alginate is a biodegradable, renewable, biocompatible, water-soluble and antiviral biopolymer with many potential biomedical applications. In this regard, this review shows 17 types of viruses that have been tested in contact with alginate and its related biomaterials. Most of these studies show that alginate-based materials possess little or no toxicity and are able to inhibit a wide variety of viruses affecting different organisms: in humans by the human immunodeficiency virus type 1, the hepatitis A, B, and C viruses, Sindbis virus, herpes simplex virus type 1 and 2, poliovirus type 1, rabies virus, rubella virus, and the influenza virus; in mice by the murine norovirus; in bacteria by the T4 coliphage, and in plants by the tobacco mosaic virus and the potato virus X. Many of these are enveloped positive-sense single-stranded RNA viruses, like SARS-CoV-2, which render alginate-based materials highly promising in the COVID-19 pandemic.

Abstract
Antiviral polymers are part of a major campaign led by the scientific community in recent years. Facing this most demanding of campaigns, two main approaches have been undertaken by scientists. First, the classic approach involves the development of relatively small molecules having antiviral properties to serve as drugs. The other approach involves searching for polymers with antiviral properties to be used as prescription medications or viral spread prevention measures. This second approach took two distinct directions. The first, using polymers as antiviral drug-delivery systems, taking advantage of their biodegradable properties. The second, using polymers with antiviral properties for on-contact virus elimination, which will be the focus of this review. Anti-viral polymers are obtained by either the addition of small antiviral molecules (such as metal ions) to obtain ion-containing polymers with antiviral properties or the use of polymers composed of an organic backbone and electrically charged moieties like polyanions, such as carboxylate containing polymers, or polycations such as quaternary ammonium containing polymers. Other approaches include moieties hybridized by sulphates, carboxylic acids, or amines and/or combining repeating units with a similar chemical structure to common antiviral drugs. Furthermore, elevated temperatures appear to increase the anti-viral effect of ions and other functional moieties.

Abstract
The thermal stability of the local structures of cucumber green mottle mosaic virus RNA, CGMMV-RNA, and tobacco mosaic virus RNA, TMV-RNA, was studied by circular dichroism (CD) and small-angle X-ray scattering (SAXS) and compared with each other in the temperature domain from 20 to 50 degrees C. The temperature dependence of the molar ellipticity and mean-square radius of the cross section of a chain shows that the structure of CGMMV-RNA is more vulnerable than that of TMV-RNA. Such a different thermal stability of their structures was also reflected in the temperature dependence of the length and number of the constituent rods when the structures of the two RNA chains were represented by a model which consisted of rods joined with freely hinged joints. From these results, a possibility was suggested that the structural stability of CGMMV-RNA and TMV-RNA might be correlated with the infectivity of the corresponding virus, CGMMV and TMV, respectively.

Abstract
Effects of temperature and ionic strength (S) on the local structure of tobacco mosaic virus RNA in phosphate buffer solution are studied by analyzing the small-angle X-ray scattering (SAXS) curves. The root-mean-square radius of a cross-section of RNA chain was kept at 0.845+/-0.005 nm over a wide range of S from 0.2 to 0.003 at 20 degrees C, whereas it gradually diminished from 0.85 to 0.61 nm when the temperature is raised from 20 to 50 degrees C at S = 0.2. Nevertheless, all of SAXS curves reflecting the backbone structures were equally mimicked by theoretical ones of freely hinged rod (FHR) models, i.e. several straight rods joined with freely hinged joints in the form of a combination of the letter Y, if the constituent rod lengths in the models are adjusted. From these facts, it is suggested that the local structure of the RNA chain in aqueous solution is characterized by an essential feature that unpaired bases in the partially double-stranded helix are constantly far isolated from each other along the helix and the rod-like structure of the helix is preserved over a range of helical contents. Such a characteristic local structure of the chain is entirely collapsed in the formamide solution at 50 degrees C.

Abstract
The differences of the reconstitution process of tobacco mosaic virus (TMV) and its mutant, cucumber green mottle mosaic virus (CGMMV) were investigated by the solution X-ray scattering measurements with the synchrotron radiation source using low-temperature quenching. The reconstitution in an aqueous solution is completely stopped below 5 degrees C. The TMV and CGMMV assembly was traced by the small-angle X-ray scattering (SAXS) measurements at 5 degrees C on a series of solutions prepared by low-temperature quenching after incubation at 20 degrees C for an appropriate interval between 0 and 60 min. The SAXS results were analyzed by the Guinier plot, the Kratky plot and the distance distribution function. The incubation of RNA and protein of CGMMV did not reconstitute at the initial reaction stages below 5 min and then began to reconstitute gradually. After 60 min, the radius of gyration for CGMMV reconstitution process reached almost the value for the initial stage of TMV reconstitution process. This is due to the fact the formation of double-layered disk in CGMMV protein is much slower than in TMV protein.
