Private Sydney-based biotech BTF has been granted a US patent for its BioBall quality-control product.

The patent protects its BioBall technology, which uses a flow cytometer to count out precisely 30 viable bacteria. The bacteria are freeze dried in a drop of nutrient fluid as a 'Bioball' pellet.

The pellets can be reconstituted and used as a control, eliminating the need for labs to perform routine serial dilutions.
