The thermo-dependence of growth kinetic parameters was investigated for the Antarctic psychrophilic strain Rhodotorula aurantiaca and a psychrotrophic strain of the same species isolated in Belgium (Ardennes area). Cell production, maximum growth rate (mu max), and half-saturation constant for glucose uptake (Ks) of both yeasts were temperature dependent. For the two yeasts, a maximum cell production was observed at about 0 degree C, and cell production decreased when temperature increased. The mu max values for both strains increased with temperature up to a maximum of 10 degrees C for the psychrophilic strain and 17 degrees C for the psychrotrophic strain. For both yeasts, Ks for glucose was relatively constant at low temperatures. It increased at temperatures above 10 degrees C for the psychrophilic strain and 17 degrees C for the psychrotrophic strain. Although its glucose affinity was lower, the psychrotrophic strain grew more rapidly than the psychrophilic one. The difference in growth rate and substrate affinity was related to the origin of the strain and the adaptation strategy of R. aurantiaca to environmental conditions. [less ▲]

The Pseudomonas putida isolate BTP1 and its sid2 mutant M3 were recently reported to protect cucumber against Pythium aphanidermatum root rot. This protection was mainly associated with an accumulation of antifungal phenolics in the treated roots. In this study, analyses of root extracts from split-root experiments showed that these phytoalexins were produced systemically. Indeed, several antifungal molecules accumulated similarly in both treated and nontreated root parts of plants protected against P. aphanidermatum with BTP1 or M3. In addition, analyses of leaf samples also revealed increased amounts of fungitoxic molecules in PGPR-treated plants, although the nature of these molecules appeared to be different from those detected in roots. The antifungal compounds isolated both from roots and leaves were mainly detected in acid-hydrolyzed extracts containing aglycones. These results suggest that PGPR can elicit phytoalexins systemically in cucumber and that the overall defence response is not based on a single phytoalexin but is chemically complex and organ-specific.

High-performance anion-exchange chromatography (HPAEC) coupled with a diode array detector (DAD) was used to identify and quantify oligogalacturonic acid components in pectins. Purified pectin lyase and polygalacturonase were used to generate unsaturated and saturated oligomers from pectins and sodium polygalacturonate, respectively. This method resulted in a good separation of saturated and unsaturated oligomers up to DP 13. It allowed us to follow polygalacturonase and pectate lyase depolymerisation pathways simultaneously.

The seed oils and cakes of netetu of different origins available on the Senegalian market have been studied to evaluate the nutritional potentialities of this important food condiment used in many African countries. The total oil content ranged from 141 to 349 g.kg-1. Careful gas chromatography and GC-MS (Gas Chromatography-Mass Spectrometry) investigations revealed seven major fatty acids among which linoleic (41.9–46.8% of the total fatty acids), oleic (12.6–14.6%), palmitic (10.2–11.3%), stearic (10.0–13.4%), and behenic (12.6–13.4%) predominate. Significant differences were observed between fermented and non-fermented seeds as well as between netetu of different origins. The tocopherol content was found very low (17.7 to 30.6 mg.100g-1 fat). The total amino acid patterns showed that beside high level of proteins (331 à 540 g.kg-1) and interesting levels of essential constituents, there is an important deficiency of tryptophane, cysteine, methionine and threonine.
