Influence of temperature on co-cultures of Ruegeria sp. R11 with S type Emiliania huxleyi (CCMP3268). R11 (102 cells/ml) was co-cultured with CCMP3268 (105 cells/ml) at 18 and 25°C and monitored over 24 days to determine the influence of temperature on co-cultures. For co-cultures and CCMP3268 grown alone, the potential quantum yield (Fv/Fm) was measured at 18°C (A) and 25°C (B). Algal cell counts (cells/ml) were measured using flow cytometry for co-cultures and CCMP3268 alone at 18°C (C) and 25°C (D). Bacterial enumeration (cfu/ml) was performed for R11 alone and in co-culture with CCMP3268 in L1-Si medium at 18°C (E) and 25°C (F). Data for R11-CCMP3268 co-cultures are indicated with orange data points and control cultures (R11 or CCMP3268 grown alone) with black data points. All control cultures and co-cultures were performed in triplicate. Error bars: ±SE.
