 Lipopolysaccharides of seven Bradyrhizobium strains and three whole-cell fatty acid preparations from bacteria isolated from nodules of Sarothamnus scoparius (Common Broom) were studied for the presence of very long chain (ω-1)-hydroxy fatty acids. Several such fatty acids were identified. Among them, straight-chain as well as mono- and dimethyl branched acids with chains in the range from 26 to 34 carbon atoms were found. Pyrrolidides and 4,4-dimethyloxazoline derivatives were used to determine the branching position. Carbons at the (ω-10) and/or (ω-11) positions in alkyl chains were points of attachment of methyl groups. These data complete the structure of bradyrhizobial lipid A with important details. The obtained results can be applied in the chemotaxonomy of Bradyrhizobium.

Periplasmic and extracellular glucans of Mesorhizobium huakuii were isolated and characterized by compositional and MALDI-TOF analyses, as well as 1H and 13C NMR spectroscopy. It was shown that M. huakuii produces a cyclic β-glucan composed entirely of nonbranched glucose chains and unmodified by nonsugar substituents. The degree of polymerisation of the cyclic oligosaccharides was estimated to be in the range from 17 to 28. The most abundant glucan molecules contained 22 glucose residues. Glucose residues within the glucan were connected by β-(1,2) glycosidic linkages. The cyclic glucan produced by M. huakuii is quite similar to the periplasmic β-(1,2) glucans synthesized by Agrobacterium and Sinorhizobium genera. The synthesis of β-glucan in M. huakuii is osmoregulated and this glucan could function as an osmoprotectant in free living cells.

A water-insoluble polysaccharide (WIP) was isolated from the fruiting bodies of Hericium erinaceus HE01 by an alkaline solution with the yield of 5%. Structural and compositional analyses by total acid hydrolysis, methylation analysis, FT-IR, FT-Raman, and ¹H NMR spectroscopy as well as other instrumental techniques showed predominantly glucose linked by α-glycosidic bonds and small amounts of mannose, xylose, rhamnose, galactose, and ribose. The methylation analysis showed that (1→3)-linked Glcp is the major constituent (70.8%) of the polymer, while the 3,4 substituted d-Glcp represents the main branching residue of the glucan. The presence of (1→3)-α-d-glucan in the hyphae of H. erinaceus was additionally confirmed by the use of specific fluorophore-labeled antibodies.
