Agro-industrial residues are primarily composed of complex polysaccharides that strengthen microbial growth for the production of industrially important enzymes. Pectinases are one of the most widely disseminated enzymes in bacteria, fungi and plants. Czapeck media supplemented with orange waste peel as carbon source under submerged fermentation process Aspergillus niger presenting the preeminent enzymatic production. On partial optimization culture showed the maximum enzyme yield (117.1 ± 3.4 mM/mL/ min) at 30 C in an orange waste peel medium having pH 5.5 and substrate concentration (4%) after 5th day of fermentation. The produced enzyme was purified by ammonium sulfate precipitation and ion exchange chromatography. A purification fold of 5.59 with specific activity and % recovery of 97.2 U/mg and 12.96% was achieved respectively after gel filtration chromatographic technique. The molecular weight of purified pectinase from A. niger was 30 kDa evidenced by SDS-PAGE. Pectinase activity profile showed purified enzyme was optimally active at pH ¼ 7 and 55 C. The maximum production of pectinase in the presence of cheaper substrate at low concentration makes the enzyme useful in industrial sectors especially for textile and juice industry.

Bioactive proteins and peptides are recognised as novel therapeutic molecules with varying biological properties for potential medical applications. Development of protein and peptidebased therapeutic products for human use is growing steadily as they continue to receive an increasing rate of approval by the United States Food and Drugs Administration (US FDA). In this short review, we describe the current status and methodologies involved in the synthesis of protein and peptide biopharmaceuticals with an emphasis on the drivers and restrains to their exploitation in the therapeutic products sector.

ESCRT (Endosomal sorting complex required for transport) machinery drives different cellular processes such as endosomal sorting, organelle biogenesis, vesicular trafficking, maintenance of plasma membrane integrity, membrane fission during cytokinesis and enveloped virus budding. The normal cycle of assembly and disassembly of some ESCRT complexes at the membrane requires the AAA-ATPase vacuolar protein sorting 4 (Vps4p). A number of ESCRT proteins are hijacked by clinically significant enveloped viruses including Ebola, and Human Immunodeficiency Virus (HIV) to enable enveloped virus budding and Vps4p provides energy for the disassembly/recycling of these ESCRT proteins. Several years ago, the failure of the terminal budding process of HIV following Vps4 protein inhibition was published; although at that time a detailed understanding of the molecular players was missing. However, later it was acknowledged that the ESCRT machinery has a role in enveloped virus budding from cells due to its role in the multivesicular body (MVB) sorting pathway. The MVB sorting pathway facilitates several cellular activities in uninfected cells, such as the down-regulation of signaling through cell surface receptors as well as the process of viral budding from infected host cells. In this review, we focus on summarising the functional organisation of ESCRT proteins at the membrane and the role of ESCRT machinery and Vps4p during MVB sorting and enveloped viral budding.

In recent years, microfluidics engineering has gained increasing research interests in assimilation and designing novel constructs for various application in bio-and non-bio sectors of the modern world. Soft and photo-lithographic fabricated devices have a potential to control the diffusion and flow of liquids in channels. The fabricated microfluidic devices of unique geometry facilitate excellent control over extracellular microenvironment and soluble factor interactions. The current devices do not only replace the in-vitro approaches but also provide a new understanding of biomolecules separation and flow in the network of microchannels. The appropriate physiological responses of cells in biological studies or drug screening analysis require engineering of active cells outside the body to enhance their maximum potential for best cellular therapy. This review work mainly focuses on the current methodologies involved in the fabrication process and limitations of cell array technology. The information is given on considerable advantages of microfluidic devices. Towards the end, potential applications covering microfluidic-based in-vitro drug analysis and analytical-based separation/detachment are discussed with potential future viewpoints.

In the late twentieth century, the only cost-effective opportunity for waste removal cost at least several thousand dollars, but nowadays, a lot of improvement has occurred. The biomass and waste generation problems attracted concerned authorities to identify and provide environmentally friendly sustainable solutions that possess environmental and economic benefits. The present study emphasises the valorisation of biomass and waste produced by domestic and industrial sectors. Therefore, substantial research is ongoing to replace the traditional treatment methods that potentially acquire less detrimental effects. Synthetic biology can be a unique platform that invites all the relevant characters for designing and assembling an efficient program that could be useful to handle the increasing threat for human beings. In the future, these engineered methods will not only revolutionise our lives but practically lead us to get cheaper biofuels, producing bioenergy, pharmaceutics, and various biochemicals. The bioaugmentation approach concomitant with microbial fuel cells (MFC) is an example that is used to produce electricity from municipal waste, which is directly associated with the loading of waste. Beyond the traditional opportunities, herein, we have spotlighted the new advances in pertinent technology closely related to production and reduction approaches. Various integrated modern techniques and aspects related to the industrial sector are also discussed with suitable examples, including green energy and other industrially relevant products. However, many problems persist in present-day technology that requires essential efforts to handle thoroughly because significant valorisation of biomass and waste involves integrated methods for timely detection, classification, and separation. We reviewed and proposed the anticipated dispensation methods to overcome the growing stream of biomass and waste at a distinct and organisational scale.
