Single-Use Systems Bioreactors in the Biopharmaceutical Industry and its Use in SARS-CoV-2 Candidate Vaccine Production - A Review

Abstract

Single-Use-Systems (SUSs) Bioreactors, also known as disposable bioreactors, have become an integral part of biotechnology manufacturing facilities for bioproducts with a potential market expecting a growth rate of nearly 15.5% over the forecast period: 2018 to 2023. SUSs bioreactors are comparatively safe, simple, and flexible than their stainless-steel bioreactors counterparts thus, their usage is being augmented in the biopharmaceutical industry mainly in planning fast tracks of complex projects, including those related to the SARS-CoV-2 pandemic. Thus, the use of SUSs has become an effective alternative for the rapid production of vaccine candidates. However, some technical and operational disadvantages still hamper their worldwide use. This review gives a rational insight into SUSs bioreactors use, types, operational parameters and new applications in the biopharmaceutical industry. Likewise, the appropriate parameters and limitations of this equipment, focusing on its use for vaccine production against COVID-19 are also discussed.
