Notes

Twenty-six species of bacteria and seven species of yeasts were aseptically presented separately as potential food sources to the estuarine heterotrich ciliate, Fabrea salina, under standardized conditions of cell number, medium, and temperature. The bacteria and yeasts were classified according to their effect on the intrinsic growth rate of the ciliate: Nutritious bacteria: Photobacterium fisherii, Vibrio neresis, V. natriegens, Flavobacterium sp. strain ASN16, V. harveyi, Xanthomonas sp. strain ASN22; Maintainer bacteria: V. vulnificus, Vibrio sp. strain V344, V. alginolyticus, V. anguillarum, Bacillus sp. strain ST3 32B2, Vibrio sp. strain V415, Acinetobacter sp. strain BHT8, Flectobacillus marinus, and Enterobacter aerogenes; Maintainer yeasts: Candida albicans and Cryptococcus marcerans strain 2; Nonnutritious bacteria: V. parahaemolyticus, Planococus sp. strain ASN13, P. mandapapanensis, Hyphomicrobium vulgari, Pseudomonas sp. strain CNS1, an unidentified gram-negative, yellow-pigmented, motile bacillus strain IG9A2, Thiobacillus thioparus, Escherichia coli, Corynebacterium sp. strain BR17, Achromobacter sp. strain 23030, and Oceanospirillum beijerinckii; Nonnutritious yeasts: C. marcerans strain 1, Saccharomyces cerevisiae, Debaryomyces hansenii, an unidentified black yeast, and C. laurentii. Under the conditions specified, bacteria appear to have a certain minimal value for the growth of Fabrea while yeast have little to none.
