Polyphenols from Brown Seaweeds as a Potential Antimicrobial Agent in Animal Feeds

Efficacy of incorporating spent seaweeds in aqua feeds as a nutritional source

Spent biomass of different seaweeds such as Sargassum wightii, Turbinaria conoides, Padina tetrastomata and Ulva lactuca were evaluated for the nutritional benefits in aqua feeds. Basic nutritional value, of seaweeds contains a number of pigments, defensive and storage compounds, and secondary metabolites that could have beneficial effects in farmed fish. Only a small fraction of algal species ...

Antimicrobial Resistance Gene Delivery in Animal Feeds

Avoparcin, a glycopeptide antimicrobial agent related to vancomycin, has been used extensively as a growth promoter in animal feeds for more than 2 decades, and evidence has shown that such use contributed to the development of vancomycin-resistant enterococci. A cluster that includes three genes, vanH, vanA, and vanX, is required for high-level resistance to glycopeptides. In the vancomycin pr...

Streptomycetes from Marine Seaweeds: Their Antimicrobial and Antibiotic Potential

Recent research has increased our knowledge and understanding of the antimicrobial effect of marine Streptomyces. In a systematic screening effect, Streptomyces isolates from different marine seaweeds were investigated for antimicrobial activity against Vibrio pathogens (V. harveyji, V. parahemolyticus, V. vulnificus and V. algniolyticus) and potentially active secondary metabolites. The differ...

Bioactive Potential and Possible Health Effects of Edible Brown Seaweeds

Antimicrobial potential of polyphenols extracted from almond skins.

AIMS To evaluate the antimicrobial properties of flavonoid-rich fractions derived from natural and blanched almond skins, the latter being a by-product from the almond processing industry. METHODS AND RESULTS Almond skin extracts were tested against Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Salmonella enterica, Serratia marcescens), Gram-positive bacteria (Listeria mon...
