Potential of chitosan from Mucor rouxxi UCP064 as alternative natural compound to inhibit Listeria monocytogenes

Abstract

Listeria monocytogenes is widely distributed in nature and the infection listeriosis is recognized as a potential threat for human health because of its mortality rate. The objective of this study was to evaluate the growth profile and chitosan production by

Antimicrobial activity of chitosan‐based films against Salmonella typhimurium and Staphylococcus aureus

“…The published researches about the antimicrobial activity include especially strong effects against bacteria ( Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Listeria monocytogenes) and fungi ( Botrytis cinerea, Fusarium oxysporum, Piricularia oryzae) (Rabea et al. , 2003; Bento et al. , 2009; Dutta et al.…”

Production, physiochemical and antimicrobial properties of fungal chitosan from Rhizomucor miehei and Mucor racemosus

“…The positive charge of chitosan, which favors interaction with the anionic charges of yeast's plasma membrane, is the reason of its antifungal activities [15]. Antibacterial activity of fungal chitosan has been shown only in a few reports [16,17]. Jeihanpour and coworkers [18] also showed that the possible mechanism for antibacterial activity of fungal chitosan could be the disruption of the outer membrane but not preventing the nutrients from entering into the cells.…”

Sensory evaluation and inhibition of Listeria monocytogenes in bovine pâté added of chitosan from Mucor rouxii

“…Over the evaluated intervals the pâté added of chitosan showed a significant lower bacterial count (p < 0.05) in respect to the control assay. Previous experiments showed that the chitosan assayed in this study at 5 mg/mL caused a greater decrease in the count of L. monocytogenes ATCC 7644 (from approximately 7 to <2 log cfu/mL) in nutrient broth at 35 C after 2 h of exposure, with no recovery in bacterial counts up to 96 h (Bento et al, 2009).…”

“…Chitosan in powder form was stored at freezing temperature until use in antimicrobial assays. Obtained chitosan presented molecular weight of 2.60 Â 10 4 g/mol and deacetylation degree of 85% (Bento, Stamford, Stamford, Campos-Takaki, & Souza, 2009). …”
