Microbial lipid and amino sugar responses to long-term simulated global environmental changes in a California annual grassland.

Frontiers in microbiology

Liang C, Gutknecht JL, Balser TC.
PMID: 25999926
Front Microbiol. 2015 May 05;6:385. doi: 10.3389/fmicb.2015.00385. eCollection 2015.

Global environmental change is predicted to have major consequences for carbon cycling and the functioning of soil ecosystems. However, we have limited knowledge about its impacts on the microorganisms, which act as a "valve" between carbon sequestered in soils...

Five closely related populations of bacteria from the Candidate Phylum (CP) Peregrinibacteria, part of the bacterial Candidate Phyla Radiation (CPR), were sampled from filtered groundwater obtained from an aquifer adjacent to the Colorado River near the town of Rifle,...

Production and Characterization of the Intra- and Extracellular Carbohydrates and Polymeric Substances (EPS) of Three Sea-Ice Diatom Species, and Evidence for a Cryoprotective Role for EPS.

Journal of phycology

Aslam SN, Cresswell-Maynard T, Thomas DN, Underwood GJ.
PMID: 27009999
J Phycol. 2012 Dec;48(6):1494-509. doi: 10.1111/jpy.12004. Epub 2012 Nov 15.

Diatoms and their associated extracellular polymeric substances (EPS) are major constituents of the microalgal assemblages present within sea ice. Yields and chemical composition of soluble and cell-associated polysaccharides produced by three sea-ice diatoms, Synedropsis sp., Fragilariopsis curta, and F....

Ion-pair RP-HPLC determination of sugars, amino sugars, and uronic acids after derivatization with p-aminobenzoic acid.

Analytical chemistry

Meyer A, Raba C, Fischer K.
PMID: 11403275
Anal Chem. 2001 Jun 01;73(11):2377-82. doi: 10.1021/ac001402s.

A new, selective, and sensitive ion-pair RP-HPLC method for the simultaneous determination of three classes of natural organic compounds, i.e., carbohydrates, amino sugars, and uronic acids, in environmental samples is presented. p-Aminobenzoic acid is used for precolumn derivatization of...

Cell walls of pseudomonas species sensitive to ethylenediaminetetraacetic Acid.

Journal of bacteriology

Wilkinson SG.
PMID: 16559075
J Bacteriol. 1970 Dec;104(3):1035-44. doi: 10.1128/jb.104.3.1035-1044.1970.

Cell walls of 12 pseudomonads considered to be sensitive to ethylenediaminetetraacetic acid (EDTA) were prepared and analyzed. The wall of each species contained protein, peptidoglycan, loosely bound lipid, and lipopolysaccharide. The walls of Pseudomonas stutzeri and P. syncyanea were...

Purification and Partial Characterization of a Lectin from Phaseolus vulgaris.

Plant physiology

Moreira Rde A, Perrone JC.
PMID: 16659942
Plant Physiol. 1977 May;59(5):783-7. doi: 10.1104/pp.59.5.783.

A method is presented for the isolation of a lectin from a Brazilian cultivar of the common bean (Phaseolus vulgaris L.), through extraction in acidic (pH 4.2) medium, fractionation with ammonium sulfate, and chromatography on DEAE-cellulose. The lectin was...

Influence of essential oil of Hyssopus officinalis on the chemical composition of the walls of Aspergillus fumigatus (Fresenius).

Mycopathologia

Ghfir B, Fonvieille JL, Dargent R.
PMID: 16333566
Mycopathologia. 1997 Jul;138(1):7-12. doi: 10.1023/A:1006876018261.

The cell walls of the growing hyphae of Aspergillus fumigatus (Fresenius) cultured in the presence or absence of the essential oil of Hyssopus officinalis were isolated and their chemical composition analysed. The presence of the essential oil led to...

The Relationship Between Lipid Peroxidation and LDL Desialylation in Experimental Atherosclerosis.

Toxicology mechanisms and methods

Oztürk Z, Sönmez H, Görgün FM, Ekmekçi H, Bilgen D, Ozen N, Sözer V, Altuğ T, Kökoğlu E.

ABSTRACT High serum total cholesterol concentration has been strongly connected with atherosclerosis in numerous studies. Being the main carrier of cholesterol in blood, low-density lipoprotein (LDL) is also the principal lipoprotein causing atherosclerosis. Sialic acids are a family of...

Bacterial catabolism of nonulosonic (sialic) acid and fitness in the gut.

Gut microbes

Almagro-Moreno S, Boyd EF.
PMID: 21327116
Gut Microbes. 2010 Jan;1(1):45-50. doi: 10.4161/gmic.1.1.10386.

The term nonulosonic acid or sialic acid encompasses a varied group of nine-carbon amino sugars widely distributed among mammals and higher metazoans. Among bacteria, the ability to synthesize sialic acid was first examined in a small number of human...

Investigation of Glycosyl Nitrates as Building Blocks for Chemical Glycosylation.

European journal of organic chemistry

Wang T, Singh Y, Stine KJ, Demchenko AV.
PMID: 31341403
European J Org Chem. 2018 Dec 19;2018(47):6699-6705. doi: 10.1002/ejoc.201801272. Epub 2018 Sep 13.

Glycosyl nitrates are important synthetic intermediates in the synthesis of 2-amino sugars, 1,2-orthoesters or, more recently, 2-OH glucose. However, glycosyl nitrates have never been glycosidated. Presented herein is our first attempt to use glycosyl nitrates as glycosyl donors for
