Recombinant pharmaceutical protein production in plants: unraveling the therapeutic potential of molecular pharming

Abstract: There is an increasing demand for the generation of recombinant pharmaceutical proteins for a wide array of therapeutic applications. In comparison to bacterial, yeast and animal cells, the production of recombinant proteins in plants with economic and therapeutic importance has only started recently. The most important prerequisite of any expression systems is that it should be simple and inexpensive. In this regard, plant-based expression has emerged an as accepted alternative to conventional expression platforms due to economic feasibility, rapid scalability, higher stability of recombinant proteins, safety due to lack of harmful substances (human, animal pathogens and pyrogens) and capability of producing proteins with desired secondary modifications. Heterologous expression using plants has played a pivotal role in the development of a myriad of recombinant proteins, including neutraceuticals and monoclonal antibodies being utilized in various therapeutic approaches. This paper presents an overview about the current status, various strategies and advantages of pharmaceutical protein production in plant expression systems. We also present a summary of expression of therapeutic monoclonal antibodies, vaccines, clinical trials and the regulatory aspects of plant-based expression. Furthermore, the challenges encountered in plant expression such as costs associated with existing purification strategies are discussed.

Biodiesel Production From Lignocellulosic Biomass Using Oleaginous Microbes: Prospects for Integrated Biofuel Production.

Abstract: Biodiesel is an eco-friendly, renewable, and potential liquid biofuel mitigating greenhouse gas emissions. Biodiesel has been produced initially from vegetable oils, non-edible oils, and waste oils. However, these feedstocks have several disadvantages such as requirement of land and labor and remain expensive. Similarly, in reference to waste oils, the feedstock content is succinct in supply and unable to meet the demand. Recent studies demonstrated utilization of lignocellulosic substrates for biodiesel production using oleaginous microorganisms. These microbes accumulate higher lipid content under stress conditions, whose lipid composition is similar to vegetable oils. In this paper, feedstocks used for biodiesel production such as vegetable oils, non-edible oils, oleaginous microalgae, fungi, yeast, and bacteria have been illustrated. Thereafter, steps enumerated in biodiesel production from lignocellulosic substrates through pretreatment, saccharification and oleaginous microbe-mediated fermentation, lipid extraction, transesterification, and purification of biodiesel are discussed. Besides, the importance of metabolic engineering in ensuring biofuels and biorefinery and a brief note on integration of liquid biofuels have been included that have significant importance in terms of circular economy aspects.
