CHEMOTACTIC AND GROWTH RESPONSES OF MARINE BACTERIA TO ALGAL EXTRACELLULAR PRODUCTS
Open accessAbstract
1. The possibility that planktonic algae possess a "phycosphere," a zone surrounding them created by the production of extracellular products which may serve as bacterial nutrients, is examined. 2. Bacterial growth in algal cultures to which no additional organic material is added is greatest only as the cultures age and algal cell lysis becomes obvious. 3. Marine bacterial isolates are chemotactic to filtrates from algal cultures, but the response is significant only to filtrates from old cultures, again where cell lysis is evident. 4. Specific compounds known to occur as algal extracellular products attract bacteria, but the threshold concentrations for attraction are unexpectedly high when compared with the generally very low concentrations of organic compounds in natural sea water. 5. The validity of the phycosphere concept and its potential importance to marine microorganisms is discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
