Equine poisoning by coffee husk (Coffea arabica L.)
BACKGROUND In Brazil, coffee (Coffea arabica) husks are reused in several ways due to their abundance, including as stall bedding. However, field veterinarians have reported that horses become intoxicated after ingesting the coffee husks that are used as bedding. The objective of this study was to evaluate whether coffee husk consumption causes intoxication in horses. RESULTS Six horses fed c...
متن کاملEndophytic bacteria in Coffea arabica L.
Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, ...
متن کاملPHYSIOLOGICAL DOSE-RESPONSE OF COFFEE (Coffea arabica L.) PLANTS TO GLYPHOSATE DEPENDS ON GROWTH STAGE
Glyphosate is the main herbicide used in coffee (Coffea arabica L.) plantations in Brazil. Problems with herbicide drift commonly occur in orchard fields due to non-adequate spraying conditions. A series of experiments was carried out aiming to evaluate physiological dose-response of C. arabica plants submitted to exposure to simulated glyphosate drift in two distinct plant growth stages. Glyph...
متن کاملProteolytic activities of bacteria, yeasts and filamentous fungi isolated from coffee fruit (Coffea arabica L.)
One hundred forty-four microorganisms previously isolated from coffee fruit (Coffea arabica) were grown on casein agar to evaluate their proteolytic activities. Fifty percent of filamentous fungi, 52.5% of bacteria and 2.6% of yeasts were able to secrete proteases. Positive isolates were further examined in liquid culture for their protease activities by hydrolysis of casein at different pH val...
متن کاملChemometric Discrimination of Coffee (Coffea arabica L.) Genotypes and Growing Origins
The objective of this work was to compare the effectiveness of three chemical families – namely elements, chlorogenic acids (CGA) and fatty acids (FA) – for the discrimination of Arabica genotypes (traditional versus modern introgressed lines) and potential terroirs within a given coffee growing area. The experimental design included three Colombian locations (Location 1, Location 2, and Locati...
