Flocculation and aggregation phenotypes of ΔgbcO mutant.
(A) Overnight cultures showing the non-flocculating NEM316 WT and complemented strain (ΔgbcOpTCVΩgbcO) and the flocculating ΔgbcO mutant. (B) Phase contrast views illustrating the morphological switch from small individual chains to large bacterial clusters characteristic of ΔgbcO mutant (Scale bar, 5 µm).
