Microbix Confirms Ramp-up of Production

Bioreactor Capacity Increasing by 500%

TORONTO, ONTARIO--(Marketwired - Nov. 27, 2017) - Microbix Biosystems Inc. (TSX:MBX), a developer and marketer of biological products and technologies, confirms its production ramp-up, with a 500% increase in bioreactor capacity and other processing upgrades.

Microbix' revenues are mainly from sales of its antigens as critical components for makers of tests that diagnose infectious diseases. Antigens are traditionally produced in thousands of "roller bottles," a method requiring considerable space, material and labour. Instead and in a significant advancement, Microbix has developed a production process using "bioreactors," a state-of-the-art technology that promises better process control and yield, with reduced space, material, and labour per unit of product.

Microbix is now scaling-up its largest-selling product into bioreactors, going from one production-oriented bioreactor to six and transferring the process from development to manufacturing. All six units have been delivered and will enter production in early 2018. A multi-month production cycle means that the full benefit of the bioreactors will be realized in the fiscal year ending September, 2019.

Additionally, Microbix is enhancing its downstream processing capacity, including a doubling of the power supply to its facility. Such modifications are also needed to support sales growth.

Collectively, these changes should enable Microbix to meet increasing demand for its products, by way of increased bioreactor capacity, enabling the reallocation of facility space to more production of other antigens and enhanced downstream processing capacity. These changes are intended to enable the double-digit sales growth now targeted by Microbix.

Phil Casselli, SVP of Sales and Business Development, commented on the significance of these changes, "Increasing our production capacity should enable us to fulfill our customers' growing need for high-quality antigens. We appreciate our customers' support during this transition."

Cameron Groome, CEO and President, provided perspectives for shareholders, "The use of bioreactors is necessary to increase sales and profitability and to realize the full potential of our antigens business. Our adoption of bioreactors for production and increasing our downstream processing capacity are evidence that our growth initiatives are fully underway."
