Summary Infections caused by antibiotic-resistant luminescent Vibrios can cause dramatic losses in aquaculture. In this study, the short-chain fatty acid b-hydroxybutyrate and its polymer poly-bhydroxybutyrate were investigated as possible new biocontrol agents. b-Hydroxybutyrate was shown to completely inhibit the growth of pathogenic Vibrio campbelli at 100 mM. Moreover, the addition of 100 mM of this fatty acid to the culture water of Artemia nauplii infected with the V. campbelli strain significantly increased the survival of the nauplii. As Artemia is a non-selective and particle filter feeder, we also investigated whether poly-b-hydroxybutyrate particles could be used to protect Artemia from the pathogenic V. campbellii. The addition of 100 mg l -1 poly-b-hydroxybutyrate or more to the Artemia culture water offered a preventive and curative protection from the pathogen as a significantly enhanced survival was noticed. If added as a preventive treatment, a complete protection of infected nauplii (no significant mortality compared with uninfected nauplii) was observed at 1000 mg l -1 poly-bhydroxybutyrate. Our data indicate that the use of poly-b-hydroxybutyrate might constitute an ecologically and economically sustainable alternative strategy to fight infections in aquaculture.

Compound heterozygosity for a Wolman mutation

Complex hydrides, containing a minimum of 7.5 wt % hydrogen, are being investigated as hydrogen storage compounds for automotive use. As a new project, the work to date has largely involved refurbishment of equipment and acquisition of study materials. Initial experiments have confirmed

Arne Shoden3 In the evolution of iron deficiency it is generally accepted that the nonfunctional iron storage compounds, hemosiderin and ferritin, are depleted before functional com-pounds such as transferrin and hemoglobin. Conversely, the iron storage compounds are the last to be replenished

ABSTRACT This paper presents a theoretical investigation of thermal and physical properties of a phase change material (PCM) consists of paraffin wax with 5% aluminum powder, this composite used as a thermal storage compound in a solar air heater, the compound supposed be encapsulated in cylinders

Carbohydrate-active enzymes (CAZymes) are involved in the metabolism of glycoconjugates, oligosaccharides, and polysaccharides and, in the case of plant pathogens, in the degradation of the host cell wall and storage compounds. We performed an in silico analysis of CAZymes predicted from

C or 5 C showed higher antioxidant capacity, total phenolics, and anthocyanins than those stored at 0 C. However, the postharvest life based on overall quality was longer at 0 C than at 5 C or 10 C. The production of aroma compounds was markedly influenced by storage time and temperature. Individual
