Each panel shows phase contrast (top left), green fluorescence (cell envelope or EPS), red fluorescence (chlorophyll a autofluorescence), and merged images. Both conditions show preserved pigment fluorescence and envelope integrity, suggesting viability and metabolic activity under suboptimal conditions.
