Biological evaluation of 32 different essential oils against Acidovorax citrulli, with a focus on Cinnamomum verum essential oil

Bacterial fruit blotch (BFB) of watermelon caused by Acidovorax citrulli (ACC) is one of the most severe diseases of watermelon worldwide. Antibacterial activity of 32 essential oils (EOs) was evaluated against ACC using disk-diffusion assays. The oil from cinnamon exhibited the greatest antibacterial activity. Using gas chromatography-mass spectrometry (GC-MS), the major components of cinnamon oil were analyzed. Among...

Treatment of domestic wastewater by anaerobic denitrification: Influence of the type of support media on the production of extracellular polymer substances

Eighteen Erlenmeyer flask containing six different support media [pozzolan, polyvinyl chloride1 (PVC1), polyvinyl chloride2 (PVC2), foam, polyethylene terephthalate (PET) and polystyrene (PS)] were subject to identical volumetric organic loadings and hydraulic retention time in treating synthetic protein ± carbohydrate waste. The objective was to examine the influence of support media on performance of anaerobic...

Iron bioavailability in tambaqui (Colossoma macropomum) desiccated gill and liver powder: Study in rats

This study assessed iron bioavailability in rats from diets enriched with desiccated tambaqui gill and liver powders using the hemoglobin depletion-repletion method. Tambaqui (Colossoma macropomum) liver and gills were bought at Manaus. After processing the livers and gills were placed on trays and desiccated in a ventilated incubator at 60°C. The rats were given free access to chow and water. The moisture, protein,...
