Dear All,
I would like to know what carotenoids are typically present in attached algae (periphyton), and especially if pro-vitamin A carotenoids other than beta-carotene (e.g., alpha-carotene and beta-cryptoxanthin) are present. Can somebody point me to a suitable reference? Any help would be greatly appreciated. Thank you very much in advance, Pete. (e-mail address: [EMAIL PROTECTED]).
