Sudhin BioSettler was demonstrated to be highly efficient at breaking oil-water emulsion and removing the oil layer continuously from the top, while the water phase is removed from the bottom of BioSettler. Based on these preliminary results reproduced at a synthetic biology company in California, Amyris, we were selected for a new R & D grant of $720,000 (Sudhin’s portion) from a new Manufacturing USA consortium, BioMADE with support from Schmidt Futures and started collaborating with Amyris after the final approval of this grant in April 2023.

Responding to a customer request, Sudhin scientists demonstrated the feasibility of breaking oil-water emulsion created by vigorous agitation by an impellor and pumped into the bottom two side ports of a 1 liter BioSettler at an inlet flow rate of about 7.5 liters/hour. The oil and water (colored red for easy visibility) phases are separated very quickly inside the BioSettler due to its numerous inclined surfaces and continuously removed from the top port and the bottom port respectively.

As the COVID year 2020 is coming to an end, We express our sympathies for many who have suffered from this pandemic. On a contrived positive note, We are happy to witness the rapid emergence of novel vaccines and antibody therapeutics, which are positive developments for the whole Biopharma industry.

At an individual company level, We are happy that my early stage companies, Sudhin Biopharma Co (US) and its subsidiary Sudhin Biotech Private Limited (India), have survived the "valley of death" during this pandemic year. In addition to the issuance of two US patents on our novel BioSettlers, early (but delayed) successful trials at select early adopter companies, we are excited to share the news of our selection for funding by Advanced Regenerative Manufacturing Institute (ARMI), a DoD funded Manufacturing USA institute.

The objectives of this new ARMI project are to demonstrate initially the use of BioSettlers for selective removal of spent media and concentrated harvest of stem cell clusters and to develop our BioSettlers over the next two years through the integration of single use fluorescent dye sensors for pH and DO into novel intelligent settling bioreactors for expansion of stem cells and concentration/harvest of stem cell clusters or organoids or viral vaccines or exosomes.

Sudhin Biopharma receives a Quick Start Project award of $1.5 Millions from National Institute for Innovation in Manufacturing Biopharmaceuticals (NNIMBL), with in-kind cost-share commitment of another $0.5 millions from a Tier 1 industrial member of NIIMBL. The project, titled “Scale-up Studies on Single Use Settlers for Clarifying Cell Culture Broth,” aims to develop a disposable plastic device for clarifying cell culture broth from a single-use bioreactor. This process is currently done by centrifugation and/or using depth filters. However, removing cells through these methods becomes challenging at high cell densities and at large scale. Through this single-use disposable settler device, cells can be separated from the secreted protein product to produce a significantly clarified product harvest stream.

Sudhin Biopharma Co. will produce and deliver 6- inch, 12-inch and 24-inch diameter single use disposable plastic settlers as part of the project. These devices will also be demonstrated as selective cell retention devices to remove dead cells and cell debris through the settler’s top effluent and to return the live and productive cells to a continuous perfusion bioreactor, which can then be operated at high cell densities, viabilities and productivities over months-long culture duration.

Inclined Settlers

Sudhin Biopharma Company has been awarded a National Science Foundation (NSF) Small Business Innovation Research (SBIR) Phase I grant for $225,000 to conduct research and development (R&D) work on demonstrating the power of our compact cell settler to achieve high cell densities and productivities in continuous perfusion bioreactor cultures of recombinant mammalian cells.

With this new grant funding, we plan to culture (i) recombinant Chinese hamster ovary cells and (ii) murine hybridoma cells in continuous perfusion bioreactors attached with our 4" or 6" compact cell settler and demonstrate that dead cells and cell debris can be removed selectively via the settler top effluent while the live and productive cells are recycled continuously to the bioreactor. Our patent-pending compact cell settler technology is a more efficiently scaled version (with much smaller footprint and higher settling capacity) of the proven "inclined settler" technology, which has been used successfully in commercial production of some therapeutic biologics. We expect to reproduce for the mammalian cell cultures our recently obtained excellent results for the smaller and hence more challenging yeast Pichia pastoris cells, demonstrating very high cell densities and productivities in continuous perfusion bioreactor for over two months without any membrane clogging or protein sieving challenges seen with other cell retention devices.

"The National Science Foundation supports small businesses with the most innovative, cutting-edge ideas that have the potential to become great commercial successes and make huge societal impacts," said Barry Johnson, Director of the NSF’s Division of Industrial Innovation and Partnerships. "We hope that this seed funding will spark solutions to some of the most important challenges of our time across all areas of science and technology."
