Abstract
An increase in the number of antibiotic resistance genes burdens the environment and affects human health. Additionally, people have developed a cautious attitude toward chemical preservatives. This attitude has promoted the search for new natural antimicrobial substances. Oligosaccharides from various sources have been studied for their antimicrobial and prebiotic effects. Antimicrobial oligosaccharides have several advantages such as being produced from renewable resources and showing antimicrobial properties similar to those of chemical preservatives. Their excellent broad-spectrum antibacterial properties are primarily because of various synergistic effects, including destruction of pathogen cell wall. Additionally, the adhesion of harmful microorganisms and the role of harmful factors may be reduced by oligosaccharides. Some natural oligosaccharides were also shown to stimulate the growth probiotic organisms. Therefore, antimicrobial oligosaccharides have the potential to meet food processing industry requirements in the future. The latest progress in research on the antimicrobial activity of different oligosaccharides is demonstrated in this review. The possible mechanism of action of these antimicrobial oligosaccharides is summarized with respect to their direct and indirect effects. Finally, the extended applications of oligosaccharides from the food source industry to food processing are discussed.

[PMID: 30263851 DOI: 10.1007/s10068-018-0332-2] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2017] [Revised: 01/24/2018] [Accepted: 02/02/2018] [Indexed: 11/29/2022] Open
Abstract
Chitosan and chitooligosaccharides were extracted from white-leg shrimp shells by chemical treatment. Low molecular weight (13 kDa) and a high degree of deacetylation (54.83%) in chitooligosaccharides led to high water solubility compared to chitosan. Antimicrobial assays indicated that chitosan and chitooligosaccharides exhibited marked inhibitory activity against food-borne pathogenics, spoilage bacterial, and fungal strains tested. However, chitooligosaccharides revealed greater inhibitory effects than chitosan on tested microorganisms. The substitution of flour by chitosan or chitooligosaccharides in bread formulation (1 g/100 g total weight basis) showed antimicrobial effects against Bacillus cereus and Rhizopus sp. growth. Also, the fruity odor in bread containing chitosan or chitooligosaccharides was delayed. Interestingly, the bread containing chitooligosaccharides showed a stronger inhibitory effect against B. cereus and Rhizopus sp. compared to bread containing chitosan and control, where B. cereus and Rhizopus sp. were observed growing on the surface of bread after 4 days of incubation at 30 °C.

Generation of chitin-derived oligosaccharides toxic to pathogenic bacteria using ChiA74, an endochitinase native to Bacillus thuringiensis. Lett Appl Microbiol 2010; 51:184-90.

Abstract
AIMS To demonstrate that an endochitinase (ChiA74) native to Bacillus thuringiensis can be used to generate chitin-derived oligosaccharides (OGS) with antibacterial activity against a number of aetiological agents of disease, including bacteria that cause diarrhoeal and emetic syndromes in humans. METHODS AND RESULTS The intact chiA74 with its cis elements was cloned into high and moderately high copy number Escherichia coli expression vectors. Functionally secreted ChiA74 was produced, and the endochitinase cleaved substrate colloidal chitin to produce OGS with 3, 5 and 6 degrees of polymerization. The enzyme was active for an extended period of incubation (24 h), but its activity showed a decrement of 73% and 87%, respectively, after 24 h of incubation at 37 and 55 degrees C. OGS showed inhibitory activity against Bacillus cereus, Listeria inoccua, E. coli, Staphylococcus xylosus, Salmonella species, Staphylococcus aureus, Pseudomona aeruginosa, Shigella flexneri, and Proteus vulgaris. CONCLUSIONS Endochitinase ChiA74 is able to stably maintain hydrolytic activity during prolonged incubation in a mix reaction with chitin to produce bioactive OGS with inhibitory activity against important food-borne pathogenic bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first study showing that an endochitinase (ChiA74) native of the most important bioinsecticide used worldwide (B. thuringiensis), but here produced in E. coli, is able to generate chitin-derived OGS with antibacterial activity against clinically significant food-borne pathogenic bacteria.
