Mikael Skournik, a professor of bacteriology at the University of Helsinki in Finland, believes that phage may be used to deal with "super bacteria."
"Super bacteria" are bacteria that are resistant to multiple antibiotics. According to the World Health Organization, 700,000 people worldwide die from “superbug†infections each year, including 230,000 newborns. Phage is a virus-hosted virus that invades bacteria and constantly replicates its own genes, eventually phagocytizing bacteria, and is considered a natural enemy of bacteria.
Skoulnik said in an interview with Xinhua News Agency recently that each phage only attacks a very limited number of bacteria and is almost specific to a certain kind of bacteria, so it may not produce normal bacteria in the human body. Bad effects. According to Sculnik, humans discovered phage and studied it at the beginning of the last century, but with the advent of antibiotics, interest in phage therapy in Western countries has gradually become indifferent.
Currently, Sculnik's research team has collected approximately 250 phage. He believes that the establishment of a better phage library requires 1,000 to 2,000 different phage, "but collecting so many types of phage takes a long time and many resources." Sculnik hopes to gradually enrich the phage library, Thereby finding and cultivating phage that can fight against "super bacteria".
Natural pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (cultures), in which vegetative colorants predominate. Natural pigments not only have the function of coloring food, but also have physiological activity. At present, there are 48 kinds of edible natural pigments approved to be used in China, commonly used chili red, beet red, monascus red, cochineal red, gaolianghong, sodium copper chlorophyllin, turmeric, gardenia yellow, carotene, algal blue pigment, cocoa pigment, caramel pigment and so on.
