pubmed-article:17777652 | pubmed:abstractText | All known species of the genera Bracteacoccus, Spongiochloris, and Dictyochloris, and some of the species of Neochloris and Spongiococcum are capable of growing heterotrophically in darkness in a glucose-salts medium. In contrast, all known species of Chlorococcum are obligate photoautotrophs. Possible relationships between these results and certain morphological characteristics are discussed. | lld:pubmed |
