Heat-derived (60°C) extracts of Limulus amoebocyte lysate (LAL) were found to contain potent “broad-spectrum” antimicrobial activity. Additional heating of the LAL extracts to 100°C for 30 min completely inactivated the antimicrobial activity a

The inactivation of bacterial endotoxin by aqueous extracts ( Limulus amoebocyte lysate) of the circulating blood cells (amoebocytes) of the horseshoe crab, Limulus polyphemus , is described. Active extracts were obtained by heating Limulus amoebocyt

The isolated cell envelope of Halobacterium salinarium strain 1 contained 15 to 20 proteins that were resolved by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. All but one of these proteins had molecular weights of 130

An ammonium-oxidizing chemolithotroph has been isolated from Alaskan waters that is different from any of the previously described species. The cells are 2.0–4.0 μm long and 1.2–2.2 μm wide. The cells contain flattened peripheral membranes that

Bactericidal activity of heat-derived (60°C) extracts of Limulus amoebocyte lysate (LAL) was found to be inhibited by low molar (10 to 100 m m ) concentrations of the monovalent cations Na + and K + . The protective effect of Na + was shown to be sp

We assessed polynucleotide sequence homologies among representative strains from four genera of ammonia-oxidizing bacteria, including three morphological types of the genus Nitrosomonas, by deoxyribonucleic acid-deoxyribonucleic acid hybridization. O

The effect of the initial substrate surface condition, as indicated by the critical surface tension for wetting, on the rate of attachment of marine bacteria to a variety of solid surfaces has been measured. The techniques used to determine the numbe

A new chemolithotrophic nitrite-oxidizing bacterium, for which the name Nitrospira marina is proposed, was isolated from the Gulf of Maine. N. marina is a Gramnegative curved rod which may form spirals with 1 to 12 turns. Cells have a unique periplas

Fatty acids in the lipids of 19 marine and terrestrial nitrifying bacteria have been analyzed. Ammonia-oxidizing bacteria have a very simple acid composition; palmitic and palmitoleic acid account for 96 to 100% of the total acids. The fatty acids of

Three diatoms from the Sargasso Sea and two diatoms and a haptophyte flagellate from an inshore area near Woods IIolc exhibited similar growth rates on urea, nitrate, and ammonia. A coccolithophore Emiliana (Coccolithus) huxleyi from the Sargasso Sea
