Effects of β-carotene on adult immune condition and antibacterial activity in the eggs of the Grey Partridge, Perdix perdix

Isolation and Characterization of Haloarchaeal Strain from Puthalam Salt Pan located in the Southern Peninsular Coast of India

“…(250%), Enterobacter sp. (140%) and Proteus vulgaris (52.8%).This may be due to the inhibition of cell wall synthesis, accumulation of lysozymes or inhibition of cell multiplication [35]. Based on these observations, it was confirmed that the test organism of the present study was found to produce secondary metabolites against E.coli, Klebsiella sp., Enterobacter sp.…”

Enhancing antimicrobial activity of TiO2/Ti by torularhodin bioinspired surface modification

“…6 The antibacterial activity of Ti/TiO 2 /PDA-T and Ti/TiO 2 /T samples, better than Cefotaxime, could be explained by the presence of TiO 2 nanotubes and torularhodin, a carotenoid pigment. Cucco et co-workers [56] suggested that carotenoids could lead to the accumulation of lysozyme, an antibacterial immune enzyme that digest bacterial cell walls, therefore generate the antibacterial activity. Reactive oxygen species can attack various targets to exert antimicrobial activity against a broad range of bacteria [57].…”

The effect of chopped, extruded and pelleted alfalfa silage on the egg quality of organic laying hens

“…The inclusion of alfalfa meal in the diets of laying hens was associated with the darkest yolk colour due to its richness in carotenoids (Cucco et al, 2007;Laudadio et al, 2014). Thus, egg yolks from laying hens fed with dehydrated alfalfa or coastal Bermuda grass showed a high concentration of total xanthophylls (Burdick and Fletcher, 1984) and a high concentration of lutein and zeaxanthin in grazing laying hens, (Skřivan and Englmaierová, 2014), which were accompanied by low L values and high a* and b* values.…”
