Lac dye, a kind of food additive and textile dye, is extracted from lac insect secretions. The ability of lac dye to stain bacteria was firstly found. Based on the discovery, a new bidirectional lateral flow immunoassay strip (BLFIS) for detecting Escherichia coli O157:H7 (E. coli O157:H7) was successfully developed. The BLFIS has two sheets of nitrocellulose (NC) membranes separated by a sample pad...
This paper was to investigate the interactions among Salmonella enteritidis, Lactobacillus plantarum, and Pseudomonas aeruginosa at four combinations of initial concentration. Firstly, fitting the growth curves to obtain growth parameters—lag time (λ), maximal growth rate (
μmax), initial concentration (N0), and maximum population density (Nmax) for each strain in monocultures or cocultures. Then...
