“…NJ6-3-1 only possess 7.45%. Though the fatty acid composition of bacterium could be changed when culturing in different conditions, the predominance of the C16 and the high values found for C16:1 ( n -7) were similar to previous results with other Pseudomonas sp., e.g., Pseudomonas atlantica [16] and Pseudomonas putida [17] both being dominated by n -7 double bonds with high concentrations of C16:1 ( n -7).…”

Among marine bacteria isolated from the cytotoxic sponge Hymeniacidon perleve , one strain NJ6-3-1 classified as Pseudomonas sp. showed both cytotoxic and antimicrobial activities. Fatty acid analysis indicated that the bacterial strain consists mainly of C16:1, C16:0, C18:1, C18:0, C15:0, C14:0. One unusual 9,10-cyclopropane-C17:0 fatty acid and C26:0 also constitute major components, as well as the existence of squalene, the precursor of triterpenoids. The major metabolites in the culture broth were identified as alkaloids, including diketopiperazines and indole compounds, namely 3,6-diisopropylpiperazine-2,5-dione, 3-benzyl-3-isopropylpiperazine-2,5-dione, 3,6-bis-(2-methylpropyl)-piperazine-2,5-dione, indole-3-carboxaldehyde, indole-3-carboxylic acid methyl ester, indole-3-ethanol, and quinazoline-2,4-dione.

“…The hydroxy fatty acid profile of Gram-negative bacteria is dependent on environmental conditions but can also greatly vary between genus and even species of bacteria (e.g. Pinkart et al, 1998). Therefore, at a given temperature and independently of other environmental conditions, the ratio of anteiso vs. normal C15 3-OH FA may strongly vary from one site to another depending on the Gram-negative bacterial communities present in soil.…”

“…This likely reflects variations in distribution of 3-OH FAs in the LPS of the Gram-negative bacterial species (e.g. Pseudomonas species, Pinkart and White, 1998; Geobacter species, Hedrick et al, 2009). Thus, 3-OH FAs with either 10, 12 or 14 C were shown to be predominant among the different Pseudomonas species (Oyaizu and Komagata, 1982), while the most abundant homologs of the genera Bacteroides and Fusobacterium were either C14 or C16 3-OH FAs (Miyagawa et al, 1979).…”

3-OH FAs containing 10 to 18 C and a hydroxyl group in third position are characteristic components of Gram-negative bacteria. These compounds were previously used to detect and quantify Gram-negative bacterial communities in various types of samples, from terrestrial, aquatic and atmospheric environments. The relative abundance of 3-OH FAs in soils was recently shown to vary with mean annual air temperature (MAAT) and pH in soils from Mt. Shennongjia (China). In the current study, the concentrations and abundances of 3-OH FAs were determined in soils from altitudinal transects under tropical and temperate climates-Mt. Rungwe (SW Tanzania) and Mt. Majella (Central Italy), respectively. The aim was to (i) examine and compare the distributions of 3-OH FAs in soils from different climatic zones and to (ii) investigate the potential of 3-OH FAs as temperature and pH proxies. When combined with previously published data, a moderate correlation (R 2 0.62) between the summed iso and anteiso to the total amount of normal 3-OH FAs (RIAN index) and pH is obtained. We show

“…This project, the NSF RUI: Microbial Observatory at Soap Lake, focuses primarily on the biogeochemistry, biomass production by, and microbial diversity of anaerobic bacterial communities in Soap Lake, WA (1). Soap Lake is an excellent choice for a Microbial Observatory because it is microbially dominated, having no macrophytes, a well characterized community of eukaryotic algae and zooplankton, and limnological data spanning the last sixty years.…”

The sulfur cycle in a permanently meromictic haloalkaline lake

Soap Lake is a haloalkaline lake located in central Washington. This lake is a remnant of the Missoula flood events that created the landscape of western Montana, the southeastern portion of Washington state, and much of Oregon. It is 15,000 -20,000 years old, and has maintained a stable meromixis for the last 10,000 years. This carbonate lake is characterized by a brackish mixolimnion, and a monimolimnion with a salinity of ~14%. The pH of both layers of the lake is approximately 10. Both layers also have a high concentration of dissolved sulfate, with the mineral mirabilite (Na 2 SO 4 ·10H 2 O) found in the monimolimnion sediments. Sulfide concentrations in the monimolimnion exceed 100 mM. As part of the mission of the NSF Soap Lake Microbial Observatory, microorganisms involved in the sulfur cycle in this lake were studied in terms of their diversity and function. High rates of sulfate reduction were measured in both layers of the lake, with new species of sulfate-reducing bacteria seen in both areas. A particularly novel psychrophilic sulfur oxidizer was isolated from the monimolimnion. This organism has the ability to induce the formation of mirabilite, which was assumed to be an abiotically deposited evaporite mineral. This is the first evidence for a biogenic origin of this mineral. This leads to the possibility that related sulfate minerals, such as those reported on the Mars surface, may have a biogenic origin.
