In the centrosymmetric title compound, [Ni(C(8)H(8)NO(3)S)(2)(H(2)O)(4)], the Ni(II) ion, which lies on an inversion centre, is six coordinated by four water mol-ecules and two propionate O atoms from two 2-pyridylsulfanylpropionate N-oxide ligands, forming a slightly distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond stabilizes the mol-ecular conformation. The crystal packi...

The biosynthetic origin of the carbon atoms in the chromophores of chrysomycins A and B was investigated in feeding experiments using 13C labeled acetates and propionate. A biosynthetic scheme is proposed involving the condensation and rearrangement of a decaketide intermediate which contains either propionate (chrysomycin A) or acetate (chrysomycin B) as the chain initiator.

ABSTRACT The carboxylate-substituted mixed-metal oxo clusters Pb6Ti6O9(acetate)(methacrylate)17 and Pb4Ti8O10(OiPr)18(acetate)2 contain a higher number of lead atoms in the cluster core than previously reported compounds. The metal atoms in both clusters are arranged in three layers of different composition, which are connected through oxygen, propionate and/or carboxylate bridges. GRAPHICAL ...

The efficacy of asthma therapy is traditionally measured using single end-points. In contrast, the aim of therapy is to achieve overall control, defined by management guidelines as achieving a number of treatment goals. These goals reflect expert opinion, rather than being evidence based. The objective of this study was to determine whether guideline-defined asthma control is achievable. Eight ...

In the centrosymmetric binuclear title complex, [Ce(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Ce(III) ions are linked by four 2-phen-oxy-propionate groups in bi- and tridentate bridging modes. Each Ce(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, two O atoms from a chelating carboxyl-ate, two O atoms derived from a μ(3)-carboxylate and two O atoms derived from two μ(2...

The effect of several fatty acid derivatives on methane and propionate in the rumen is described. A possible explanation for the observed inverse relationship between methane and propionate is given.

Here, we report the draft genome sequence of Veillonella tobetsuensis ATCC-BAA 2400(T). This bacterium has the remarkable ability to form oral biofilms. The genome is predicted to encode the necessary enzymes involved in the pathway that facilitates the conversion of lactate to propionate.

Glucose entry rates, propionate production rates and the conversion of propionate into glucose were measured in sheep given diets varying in protein and energy content. Glucose entry rate increased linearly (P<O.Ol ) with the estimated intake of digestible energy and with crude protein intake as did concentrations in the rumen of propionate and total VFA. There was, however, little variation in...

the use of propionate agar resulted in very low yeast counts in samples of plant material as compared to the populations obtained with acidified dextrose agar and synthetic agar. Acidified synthetic agar proved to be the medium of choice for the enumeration and isolation of yeasts from plant material. Counts obtained on this medium were comparable to those on acidified dextrose agar and mold gr...
