The major carotenoids in pigmented extreme halophiles are the hydroxylated C50 red pigments bacterioruberin (major, 84%) and monoanhydrobacterioruberin (minor, 14%). When cells of Halobacterium cutirubrum were grown in the presence of nicotine they accumulated lycopene and bisanhydrobacterioruberin; maximal accumulation (80% lycopene, 20% bisanhydrobacterioruberin) occurred at 3mM nicotine. Removal of nicotine resulted in the reformation of monoanhydrobacterioruberin and bacterioruberin at the… CONTINUE READING
