“…Membranes prepared from P. putida containing high levels of cytochrome d exhibited increased resistance to cyanide inhibition of succinate and NADH oxidations, but not TMPD oxidation (18). The oxidation of TMPD is also confined to a cyanide-sensitive branch of respiratory systems in Beneckea natriegens (44) and A. vinelandii (19). The results obtained in the present study of Acinetobacter suggest that electrons from TMPD are not limited to a particular branch of the respiratory pathway.…”

The electron transport system of Acinetobacter sp. HO1-N was studied to determine the specific cytochromes and to measure changes in the composition of the respiratory system due to growth in various concentrations of oxygen or types of growth substrates. Spectrophotometric analysis revealed that the quantity and types of cytochromes changed in response to growth under various concentrations of oxygen. Growth on alkane and nonalkane substrates resulted in only minor differences in cytochrome composition or oxidase activities. Membranes prepared from cells grown under oxygen-limiting conditions contained at least one b-type cytochrome, cytochrome o, cytochrome d, and slight traces of cytochrome a1, whereas membranes prepared from cells grown in the presence of high oxygen concentrations contained only low levels of cytochromes b and o. Polarographic measurements, electron transport inhibitor studies, and photoaction spectrum analyses indicated that cytochromes o, a1, and d were potentially capable of functioning as terminal oxidases in this organism. These experiments also revealed that all three cytochromes may be involved in the oxidation of reduced nicotinamide adenine dinucleotide, succinate, or N,N,N',N'-tetramethyl-p-phenylenediamine.

“…Relatively little is known, as yet, about bacterial oxidases, but information that is accumulating indicates that respiratory chains are branched in some organisms, with separate branches having terminal oxidases with individual properties (7,13,14).…”

Localization of tetramethylphenylenediamine-oxidase in the outer cell wall layer of Neisseria meningitidis

A highly active tetramethylphenylenediamine-oxidase has been found in association with the cell wall blebs, evaginations of the outer wall membrane, of Neisseria meningitidis. Isolated wall blebs consumed oxygen in the presence of ascorbate-tetramethylphenylenediamine but not in the presence of succinate, whereas cell envelope preparations are active on both substrates. The ratio of succinate dehydrogenase/tetramethylphenylenediamine-oxidase activities in preparations of envelopes was approximately 100 times that in isolated wall blebs, indicating that the outer membrane preparations were highly purified.

“…Beneckea natriegens (4, 5) is a marine bacterium originally isolated from salt marsh mud (23) and grows extremely well in the laboratory (9,22). The metabolic (7,(10)(11)(12)25) and respiratory capabilities of B. natriegens (18,(35)(36)(37)(38), as well as its characteristic marine requirement for sodium ions for protein synthesis and growth, have been studied in detail (23, 24, [27][28][29][30]34). Bacteriophages active against B. natriegens are widely distributed in coastal salt marshes, where they appear to be abundant and can be easily isolated (40).…”

The effects of variation in ionic levels on the stability and replication of two bacteriophages (nt-1 and nt-6) host specific for the marine bacterium Beneckea natriegens were examined. Monovalent cations influenced the adsorption of the nt-1 but not the nt-6 phage; however, one-step growth studies showed that NaCl was required for replication of both phage. The NaCl optimum for nt-1 production was 0.25 M NaCl, the same as the growth optimum for B. natriegens. However, the optimum for nt-6 production was 0.16 M NaCl. These NaCl optima for host and phage are at estuarine rather than oceanic levels. The nt-1 phage was better suited to replicate at NaCl levels typical of higher salinity areas (18-35%,,) and the nt-6 phage was better suited to replicate at lower salinities (5-18%.,). The nt phage were more resistant to low NaCl levels than their host bacterium and appeared limited to marine waters by the lower survival salinity of B. natriegens coupled with phage inactivation processes occurring in natural estuarine waters.
