| Inhoud: |
The polyamines, putrescine, spermidine, spermine and norspermine, were detected in both the free and conjugated fractions of Chattonella antiqua cells, and putrescine and spermidine were detected in the bound polyamine fraction. Of the free polyamines, spermidine was the most abundant throughout the growth period and increased strongly during the exponential growth phase. The free spermidine content increased linearly with growth rate. The maximum growth yield of C. antiqua was reduced in proportion to the concentration of methylglyoxal bis-(guanylhydrazone) (MGBG). The inhibition of growth by MGBG could be counteracted by the addition of spermidine to the medium. It is suggested that free spermidine plays a significant role in C. antiqua growth. |
