Aminolipids elicit functional trade-offs between competitiveness and bacteriophage attachment in Ruegeria pomeroyi. THE ISME JOURNAL 2023; 17:315-325. [PMID: 36477724 PMCID: PMC9938194 DOI: 10.1038/s41396-022-01346-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 11/17/2022] [Accepted: 11/21/2022] [Indexed: 12/12/2022]
Abstract
Lipids play a crucial role in maintaining cell integrity and homeostasis with the surrounding environment. Cosmopolitan marine roseobacter clade (MRC) and SAR11 clade bacteria are unique in that, in addition to glycerophospholipids, they also produce an array of amino acid-containing lipids that are conjugated with beta-hydroxy fatty acids through an amide bond. Two of these aminolipids, the ornithine aminolipid (OL) and the glutamine aminolipid (QL), are synthesized using the O-acetyltransferase OlsA. Here, we demonstrate that OL and QL are present in both the inner and outer membranes of the Gram-negative MRC bacterium Ruegeria pomeroyi DSS-3. In an olsA mutant, loss of these aminolipids is compensated by a concurrent increase in glycerophospholipids. The inability to produce aminolipids caused significant changes in the membrane proteome, with the membrane being less permeable and key nutrient transporters being downregulated while proteins involved in the membrane stress response were upregulated. Indeed, the import of 14C-labelled choline and dimethylsulfoniopropionate, as a proxy for the transport of key marine nutrients across membranes, was significantly impaired in the olsA mutant. Moreover, the olsA mutant was significantly less competitive than the wild type (WT) being unable to compete with the WT strain in co-culture. However, the olsA mutant unable to synthesize these aminolipids is less susceptible to phage attachment. Together, these data reveal a critical role for aminolipids in the ecophysiology of this important clade of marine bacteria and a trade-off between growth and avoidance of bacteriophage attachment.

Abstract
Bacterial diversity of reed (Phragmites australis) periphyton communities of Kelemen-szék and Nagy-Vadas (two Hungarian soda ponds) was investigated using molecular cloning and cultivation-based techniques. The majority of the 80 Kelemen-szék and 72 Nagy-Vadas bacterial isolates proved to be moderately halophilic and alkaliphilic. A great proportion of the isolates showed phosphatase and urease activity, utilized aesculin, citrate and certain biopolymers (e.g., gelatine and tween 80). Partial 16S rDNA sequence analysis of 33 Kelemen-szék and 20 Nagy-Vadas ARDRA group representatives showed Gram-positive (Nesterenkonia, Cellulomonas, Dietzia, Bacillus and Planococcus) dominance at both sampling sites. Species of the genera Acidovorax, Hydrogenophaga (beta-Proteobacteria) and Flavobacterium, Sphingobacterium (Bacteroidetes) were represented only from Kelemen-szék. Altogether 16 isolates showed low sequence similarity with yet described bacteria and may represent novel taxa. Screening of the 16S rRNA gene libraries of 129 Kelemen-szék and 158 Nagy-Vadas clones resulted in 30 and 28 different ARDRA groups, respectively. Sequence analysis revealed a Gram-negative (Rheinheimera, Aquimonas, Cellvibrio, Flavobacterium and Sphingobacterium) dominated phylogenetic diversity. A high number of the clones were affiliated with uncultured bacterial clones described from diverse environmental samples.

Abstract
A marine bacterium, Myroides sp. SM1, can grow on weathered crude oil and show emulsification of it. The biosurfactant able to emulsify crude oil was excreted in culture supernatant of Myroides sp. SM1 grown on marine broth, which was extracted with chloroform/methanol (1:1) at pH 7 and purified by normal and reverse phase silica gel column chromatographies. The compound was ninhydrin-positive, and the chemical structure was elucidated by nuclear magnetic resonance (NMR), infrared spectroscopy (IR), fast atom bombardment mass spectrometry, and gas chromatography-mass spectrometry (GC-MS) to be a mixture of L: -ornithine lipids, which were composed of L: -ornithine and a different couple of iso-3-hydroxyfatty acid (C(15)-C(17)) and iso-fatty acid (C(15) or C(16)) in a ratio of 1:1:1. The critical micelle concentration for a mixture of ornithine lipids was measured to be approximately 40 mg/l. A mixture of ornithine lipids exhibited emulsifying activity for crude oil in a broad range of pH, temperature, and salinity and showed higher surface activity for oil displacement test than other several artificial surfactants and a biosurfactant, surfactin.

Abstract
Gram-negative bacteria characteristically are surrounded by an additional membrane layer, the outer membrane. Although outer membrane components often play important roles in the interaction of symbiotic or pathogenic bacteria with their host organisms, the major role of this membrane must usually be to serve as a permeability barrier to prevent the entry of noxious compounds and at the same time to allow the influx of nutrient molecules. This review summarizes the development in the field since our previous review (H. Nikaido and M. Vaara, Microbiol. Rev. 49:1-32, 1985) was published. With the discovery of protein channels, structural knowledge enables us to understand in molecular detail how porins, specific channels, TonB-linked receptors, and other proteins function. We are now beginning to see how the export of large proteins occurs across the outer membrane. With our knowledge of the lipopolysaccharide-phospholipid asymmetric bilayer of the outer membrane, we are finally beginning to understand how this bilayer can retard the entry of lipophilic compounds, owing to our increasing knowledge about the chemistry of lipopolysaccharide from diverse organisms and the way in which lipopolysaccharide structure is modified by environmental conditions.

Phenotypic variation of lipid composition in Burkholderia cepacia: a response to increased growth temperature is a greater content of 2-hydroxy acids in phosphatidylethanolamine and ornithine amide lipid.

Abstract
Burkholderia cepacia produces an unusual range of polar lipids, which includes two forms each of phosphatidylethanolamine (PE) and ornithine amide lipid (OL), differing in the presence or absence of 2-hydroxy fatty acids. By using chemostat cultures in chemically defined media, variations in the lipid content and the proportions of individual lipids have been studied as a function of (a) growth temperature, (b) growth rate and (c) growth-limiting nutrient (carbon, magnesium, phosphorus or oxygen). Total cellular lipid in carbon-limited cultures was lowest at high growth temperatures and low growth rates. Increases in growth temperature over the range 25-40 degrees C led to increases in the proportions of molecular species of PE and OL containing 2-hydroxy acids, without changing the PE:OL ratio. Growth temperature did not alter the balance between neutral and acidic lipids, but the contribution of phosphatidylglycerol to the latter increased with rising growth temperature and growth rate. Pigmentation of cells and the presence of flagella were also temperature-dependent. Change in growth rate also affected the PE:OL ratio and the extent to which monoenoic acids were replaced by their cyclopropane derivatives. Whereas similar lipid profiles were found for carbon-, magnesium- and oxygen-limited cultures, ornithine amides were the only polar lipids detected in phosphorus-limited cells.

Abstract
The extractable lipids of the PC-producing, methylotrophic, budding bacterium Hyphomicrobium vulgare NP-160 grown in a mineral-salts medium containing methanol as the carbon source, were studied by chromatographic and spectrometric methods. They were found to be comprised of PC (35% of the total lipids), PDME (33%), PMME (1%), PE (9%), PG (10%), DPG (6%), and a non-phosphorus, ornithine-containing lipoamino acid, OL (6%). No low-polarity lipids, such as fatty acid esters of glycerol or of other alcohols, were detected. The sole fatty-acyl constituents of PDME and PMME were cis-octadec-11-enoic (cis-vaccenic) acid residues, whereas the other phospholipids contained, in addition, 1 to 5 mol % of MOA (lactobacillic acid) residues located predominantly at the sn-1 position of their glycerol residues. OL consisted of two molecular species, 2-N-[3'-(cis-octadec-11"-enoyloxy)octadecanoyl]-L- ornithine and 2-N-[3'-(cis-11", 12"-methyleneoctadecanoyloxy)octadecanoyl]-L-ornithine in the molar ratio 94:6. When the culture medium was devoid of phosphate, a threefold increase in OL together with a three-fold decrease in PE were observed, no significant changes in proportions of the remaining lipids occurring. The most striking feature of the lipid composition in this case was the presence of considerable amounts of fatty acid methyl esters, mainly methyl cis-vaccenate, along with minute amounts of wax esters.

Abstract
The gram-negative gliding bacterium Cytophaga johnsonae contains not only large quantities of unusual sulfonolipids but also, as we report here, a second class of unusual lipids. These lipids were detected and quantified by two-dimensional thin-layer chromatography of lipids from cells grown in the presence of [14C]acetate and shown by chemical studies to be alpha-N-(3-fatty acyloxy fatty acyl)ornithines. Like the sulfonolipids, these ornithine lipids were localized in the outer membrane (whereas phosphatidylethanolamine was the predominant lipid of the inner membrane). In a sulfonolipid-deficient mutant, the missing lipid was replaced, specifically, by an increased amount of ornithine lipid. Cells grown in liquid media contained predominantly ornithine lipids with nonhydroxylated residues in the O-fatty acyl position. In contrast, surface-grown cells contained a high proportion of ornithine lipids in which the O-fatty acyl group was 3-hydroxylated. The sulfonolipids and ornithine lipids are apparently coregulated in the sense that, regardless of perturbations caused by mutation or growth conditions, their total amounts remain constant at 40% of total cell lipid.

Abstract
Paracoccus denitrificans grown in a complex medium was highly susceptible to lysozyme, in contrast to cells grown in a complex medium supplemented with Mg2+ and Ca2+ or in a succinate-salts medium. The complex medium was deficient in divalent cations needed for optimum outer membrane stability. The major change in molecular compositions of outer membranes isolated from cells grown under the different conditions was a higher ratio of ornithine-containing lipid to phospholipid in complex-medium-grown cells (0.63) than in cells grown in complex medium with Mg2+ and Ca2+ (0.22) or in succinate-salts medium (0.14). We suggest that the dipolarionic ornithine-containing lipid is less dependent than acidic phospholipids on divalent cations for its incorporation into the outer membrane.

Abstract
An ornithine containing aminolipid has been found in Thiobacillus ferrooxidans grown in ferrous sulfate medium, which was purified and estimated at four main phases of growth. GLC analysis of ornithine lipid has revealed the existence of mainly C18:1 and C22:1 fatty acids. The infrared spectra showed the existence of both amide and ester linkages in the aminolipid. The major ester linked fatty acid was C22:1. The interaction of ornithine lipid with membrane was investigated by delipidation of the membrane particles, which resulted in the perturbation of the activities of the three enzymes of iron oxidation system. The activities could be restored to the lipid depleted particles by preincubation with a dispersion of purified ornithine lipid together with coenzyme Q8. The kinetic parameters of the enzyme activities were also affected by delipidation which was significantly altered in the reconstituted particles by this lipid, thus indicating a possible role of ornithine lipid in iron oxidation system.
