Effects of temperature on growth, pigment composition and protein content of an Antarctic Cyanobacterium Nostoc commune
biomass accumulation, pigment composition and protein content were studied for the cyanobacterium Nostoc commune, isolated from Antarctica. Results confirmed the psychrotrophic behavior (optimum growth temperature 250C) of the cyanobacterium. Low temperature increased the duration of lag phase and e...
