A study was carried out with the objective of determining presence Bacillus cereus in eggshells commercialized Mexico, enterotoxigenic profile isolated strains, and production biofilms different materials as well eggshell. 1000 chicken eggs from four commercial brands were collected markets supermarkets located city Chilpancingo, Mexico. The molecular identification by amplification gyrB gene p...

The aim of this study was to investigate the effect of sodium dodecyl sulfate (SDS), citric acid, and hydrogen peroxide (H2O2), alone or in combination, on reducing the population of four foodborne pathogens, including Escherichia coli, Listeria monocytogenes, Salmonella typhimurium, and Staphylococcus aureus on eggshells. In each series of tests, eight fresh eggs were inoculated with each bact...

Hydroxyapatite bio-ceramic powder was synthesized using waste eggshells as calcium source by a straight forward thermal method. The process is carried out at high temperature. Different calcium phosphate phases were obtained just by changing the thermal treatment. HAp is the only apatite present in the reaction products, along with minute fractions of other calcium compounds. The final product ...

Drone brood is a little-known bee product, often treated as beekeeping waste or natural varroosis bait. Obtaining drone from beehives does not weaken the family, which why this product used medicine in Eastern European countries. The main objective of work was to design an innovative dietary supplement containing freeze-dried (DB) enriched with calcium ions (3:1). As component, inorganic carbon...

In this study, an innovative composite was fabricated in which the matrix is partially derived from natural sources and filler undervalued eggshell waste material. The effect of coating eggshells mineral limestone with 2 wt.% stearic acid on mechanical properties a bio-epoxy investigated. Eggshells (untreated acid-treated) fillers were added to quantities 5, 10, 20 loadings using solution mixin...
