Which risk rises when a bio-reactor's impeller speed diminishes?

💡 Explanation

Lower impeller speed reduces mixing, decreasing oxygen distribution; therefore a dissolved oxygen gradient forms because diffusion becomes inadequate, rather than achieving uniform conditions, and this inhibits aerobic processes.
