摘要：

Chloroflexus aurantiacus grown in batch culture took up exogenous alcohols and incorporated these into bacteriochlorophyll c as the esterifying alcohol. It was possible to change the distribution of the naturally occurring homologs of bacteriochlorophyll c esterified with phytol, hexadecanol, and octadecanol by adding the appropriate alcohol. The corresponding homolog then made up at least 60% of the cellular bacteriochlorophyll c. It was also possible to obtain novel bacteriochlorophyll homologs not found in detectable amounts in control cells by adding fatty alcohols with short chains (C10, C12) or long chains (C20). These changes in bacteriochlorophyll composition had no detectable effects on the spectral properties of the chlorosomes.
