    Abstract Cell yields were determined for two bacterial soil isolants grown aerobically in minimal media on a variety of synthetic organic compounds. 1-Dodecanol, benzoic acid, phenylacetic acid, phenylglyoxylic acid, and diethylene, triethylene, and tetraethylene glycols were tested. Two "biochemicals," succinate and acetate, were also tested for comparison. Yields were calculated on the basis of grams of cells obtained per mole of substrate utilized, gram atom of carbon utilized, mole of oxygen consumed, and equivalent of "available electrons" in the substrates. This latter value appears to be nearly constant at 3 g of cells per equivalent of "available electrons." Yields predicted on this basis for other bacteria and for yeasts on other substrates are in fair agreement with reported values.

    Abstract Five strains of Legionella pneumophila were examined for the presence of hydroxy fatty acid. The cellular distribution of the fatty acids was also determined, as was the variation of hydroxy acid production on five growth media. The strains tested all produced approximately 5 mol% of hydroxy fatty acid, most of which was found in the nonextractable, alkali-stable, acid-labile (wall-associated, amide-linked) fraction. Three major hydroxy acids were found, along with several minor components. The major hydroxy acids were analyzed by thin-layer chromatography, gas-liquid chromatography, mass spectrometry, and infrared spectrophotometry. These compounds were tentatively identified as 3-hydroxy-12-methyltridecanoate, 3-hydroxy-n-eicosanoate, and a novel dihydroxy acid, 2,3-dihydroxy-12-methyltridecanoate. The total amount of hydroxy acid produced, as well as the profile of the hydroxy acids, remained relatively unchanged with respect to strain and growth medium.

    Abstract Two strains of Bacteroides asaccharolyticus and two strains of Bacteroides fragilis were analyzed for total fatty acid, total lipid fatty acid, and total bound fatty acid profiles. Extracted lipids and defatted cell residues were subjected to sequential alkaline and acid methanolyses to distinguish ester- and amide-linked fatty acids in each fraction. In the lipid fractions, all the ester-linked fatty acids were nonhydroxylated, whereas all of the amide-linked fatty acids were hydroxylated. In the nonextractable fractions, both hydroxy and nonhydroxy fatty acids were found in both ester and amide linkage, although hydroxy acids predominated. The fatty acid profiles of the bound fractions differed widely from those of the lipid fractions. Bound fatty acid represented approximately 10% of the total cellular fatty acids.

    Abstract Acid hydrolysates of 140 strains, representing 11 species of the genus Bacteroides, were analyzed by capillary gas-liquid chromatography for total cellular fatty acid. All samples contained components which appeared to be hydroxy fatty acid. The relative amount and chain length distribution of the hydroxy fatty acids, as well as the nonhydroxy fatty acids, varied according to species. To characterize the presumed hydroxy acids, a composite of some 40 of these samples was analyzed by thin-layer and capillary gas-liquid chromatography, mass spectrometry, infrared spectrophotometry, and polarimetry. The hydroxy acids were shown to be of the D-(--)-3-hydroxy acid family. The predominant component was the iso-branched D-(--)-3-hydroxy-15-methylhexadecanoic acid. Lesser amounts of the iso-branched 15-carbon, straight-chain 16-carbon, and anteiso-branched 17-carbon acids were also found.

    Abstract Water-soluble protein extracts were obtained from representative strains of eleven species of Legionella and examined by polyacrylamide slab gel electrophoresis (PAGE). The eleven species included: L. pneumophila (serogroups 1-9), L. micdadei, L. longbeachae (serogroups 1 and 2), L. gormanii, L. dumoffii, L. bozemanii, L. jordanis, L. oakridgensis, L. wadsworthii, L. feeleii and L. maceachernii. Species identification was verified by gas-liquid chromatography of the non-hydroxy, monohydroxy and dihydroxy fatty acids. Strains within each species shared common patterns of protein banding. Each species had a distinctive protein banding pattern. Results indicate that PAGE of water soluble protein extracts is a useful technique for identification of Legionella isolates.

    Abstract Acholeplasma axanthum is one of the few procaryotes, and the only member of the Mollicutes, known to contain phosphosphingolipids. Examination of strain S743 for glycolipids revealed the presence of glucosides of cholesterol and galactosides of glycerol as the predominant glycolipids. The major component is acylated diglucosylcholesterol, followed by monogalactosyldiacylglycerol and monoglucosylcholesterol. The glucose residues of the sterol-based compounds appear to be alpha-linked pyranoses, while the galactose of the glycerol-based lipid is an alpha-linked furanose. The "glycolipid' fraction also contained N-(3-hydroxy)acyl sphinganines with varying degrees of O-acylation. None of these ceramide derivatives was linked to carbohydrate. The major glycolipid, tentatively identified as alpha-D-glucopyranosyl-(1 leads to 3)-(O-acyl)-alpha-D-glucopyranosyl-(1 leads to 3)-cholesterol, along with its deacylated derivative, appears to be the first reported instance of steryl diglycosides among procaryotes, in contrast to the steryl monoglycosides, which are common to other mycoplasmata and some spirochetes.

    Abstract A long-chained polyalcohol (polyol) was isolated from the glycolipid fraction of the extreme thermoacidophile Bacillus acidocaldarius. The polyol and its Smith degradation products, as well as the alkanes derived from these compounds were characterized by mobility on thin-layer and gas-liquid chromatography, and by infrared and mass spectrometry. The polyol is proposed to be a fully saturated pentacyclic tetrol (C35H62O4, Mr 546) containing a 1,2,3,4-tetrahydroxy pentane substituted to a hopane-derived pentacyclic triterpene nucleus.

    Abstract Lipopolysaccharide (LPS) from Haemophilus pleuropneumoniae 1536, serotype 2, was isolated and purified by a procedure designed to be equally satisfactory for both smooth- and rough-type LPS. The LPS yield was 53%. Analysis of the preparations revealed that protein, nucleic acid, and cellular phospholipid contamination was negligible (less than 0.1%). Analysis of the sugar content of the LPS by gas-liquid chromatography and colorimetric analysis revealed the presence of rhamnose, mannose, galactose, glucose, heptose, glucosamine, galactosamine, and 3-deoxy-D-manno-2-octulosonic acid. The heptose and glucose contents appeared to be unusually high. The fatty acids of the LPS consisted of a mixture of C14:0 and C16:0 in a ratio of about 4.5:1 (50% of the total) and 3-hydroxy C14:0. When used as a preparatory dose for the dermal Shwartzman reaction, as little as 10 micrograms of the LPS injected intradermally in rabbits produced reddening and swelling. After intravenous injection of a 100-micrograms LPS provoking dose, necrosis was observed at all intradermal injection sites. Limulus amebocyte lysate gelation was observed with an LPS concentration as low as 0.5 ng/ml. A typical biphasic fever response was noted in rabbits injected with as little as 0.25 ng of LPS per kg of body weight.

    Abstract This study was conducted to identify, and characterize rumen bacteria that are able to degrade the toxic compound, 3-hydroxy-4(lH)-pyridone (3,4 DHP), that is produced in the rumen from mimosine. Mimosine is a non-protein amino acid that is found in leaves and seeds of Leucaena leucocephala, a leguminous tree used as a forage crop for ruminants in the tropics, and degradation of 3,4 DHP by ruminal microbes is critical for protection of animals from leucaena toxicity. Microbes with this capacity are, however, not ubiquitous and microbial populations in the rumens of animals in some parts of the world are unable to metabolize 3,4 DHP. Four strains of obligately anaerobic, gram-negative, rod-shaped bacteria that degrade 3,4 DHP were isolated from rumen contents from a goat in Hawaii. The isolates do not ferment carbohydrates, but are able to use both 3,4 DHP and its isomer, 3-hydroxy-2(lH)-pyridone (2,3 DHP), as well as arginine and histidine as substrates for growth. Comparisons of the 16S rRNA sequence from one of these isolates with sequences from a widely diverse group of bacteria agree with other information indicating that these isolates do not fit into any existing taxon. Thus, we are hereby proposing a new genus and species designation, Synergistes jonesii, for these organisms.
