Direct exchange of vitamin B12 is demonstrated by modelling the growth dynamics of algal–bacterial cocultures (original) (raw)

“…After 7 days of cultivation, algal productivity was 4.8 and 3.4 times higher in the systems supplemented with bacteria. The stimulative effect of bacteria on algal growth has been described as being associated with bacteria mineralizing carbon (Ask et al, ; Muñoz and Guieysse, ), as well as cycling nutrients (Bloesch et al, ; Zhao et al, ) and generating vitamins (Grant et al, ) and other growth promoting regulators. Considering inorganic carbon limitation, this work focuses on bacterial stimulation via mineralizing photosynthetic end products.…”

“…Previous work has shown that the presence of bacteria may aid algal productivity (Andersen, ; Fukami et al, ; Riquelme et al, ; Suminto and Hirayama ). The stimulative effect of bacteria on algal growth has been described as being associated with bacteria mineralizing carbon (Ask et al, ; Muñoz and Guieysse, ), as well as cycling nutrients (Bloesch et al, ; Zhao et al, ) and generating vitamins (Grant et al, ) and other growth promoting regulators. Considering bacteria mineralizing carbon, this carbon cycling process has potential to help overcome carbon limitation in open algal culture systems.…”
