Abstract

Two numerically important bacteria in marine pulp mill effluent enrichment cultures were isolated. These organisms were gram-negative, rod-shaped, strictly aerobic bacteria. Isolate IRE-31T (T = type strain) produced hydrolytic enzymes for the breakdown of cellulose, xylan, chitin, gelatin, and Tween 80. It also utilized a variety of monosaccharides, disaccharides, amino acids, and volatile fatty acids for growth. Isolate KW-40T did not utilize natural polymers, but it could grow on a variety of monosaccharides, disaccharides, alcohols, and amino acids. It also utilized methanol and aromatic compounds. The surfaces of both organisms were covered by blebs and vesicles. 16S rRNA analyses placed both organisms in the gamma-3 subclass of the phylum Proteobacteria. They were related to Oceanospirillum linum, Marinomonas vaga, Pseudomonas putida, and Halomonas elongata, although a close association with any of these bacteria was not found. The guanine-plus-cytosine contents of strain IRE-31T and KW-40T were 57.6 and 54.9 mol%, respectively. On the basis of 16S rRNA sequence and phenotypic characterizations, these isolates were different enough so that they could be considered members of new genera. Thus, the following two new genera and species are proposed: Microbulbifer hydrolyticus, with type strain IRE-31 (= ATCC 700072), and Marinobacterium georgiense, with type strain KW-40 (= ATCC 700074).

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.
