As part of the work of the International Laboratory of Food Ingredients Synthesis and Analysis, scientists demonstrated that Bidens pilosa leaf extract accelerates protein breakdown, which makes it suitable. To obtain biologically active compounds such as tyrosine, was first isolated from cheese in 1846, and among proteins expressed by all living organisms.

“There is a long tradition of using Bidens pilosa as a medicine. Due to its popularity, in our opinion, its use is extremely beneficial in winemaking and dairy processing, where Bidens pilosa extract can become a substitute for a wide variety of food animal enzymes, ”said Irina Potoroko, Dean of the Department of Food Technology and Biotechnology.
In experiments, researchers demonstrated that the fresh leaves of Bidens pilosa had high protease activity at pH 4 acid buffer (8,2567 × 10-7 mM / mg / min) compared with alkaline buffer pH 10 (5 , 15 × 10-7 mM / mg / min) at 30 degrees C. Scientists were able to determine the optimal conditions for the enzyme activity of the leaf extract, making it possible to use different technology process.
Irina Potoroko believes that further research is needed to find out which part of the plant (roots, stems, flowers) has the greatest protease activity, because research conducted at SUSU focuses on fresh leaves only.
At the next stage of work, the team plans to study the packaging, transport and release mechanism of the Bidens pilosa extract to increase the efficiency of the fermentation processes.
Bidens pilosa is cultivated worldwide as a weed imported from the US. In Russia, the tree is found in the Far East. Bidens pilosa is a quarantine weed that is banned from import.
This biologist published the results of his research at KIT’s Botanical Institute in his doctoral dissertation titled “Allergic compounds from mint to target bio-magnetic cell skeletons. Cell-oriented application as a biological herbicide. ” In his dissertation, he reported that the aroma of monarda perfect targets the actin protein and induces its cell self-destruction. It is especially effective against seaweed. In this case, the Weeds 2020 very bad would not recommend shirt researchers understood the mechanism, although they had yet to identify the substance that caused this effect. Studies by Sarheed at KIT also revealed that menthos inhibited the growth of HeLa cells – human cancer cells -. “This makes it used as an anti-cancer agent,” said the scientist, whose research was funded by the Iraqi Ministry of Education and Research and KIT’s young scientist Karlsruhe.
Weeds are one of the main causes of crop failure. They compete with crops for the same ecological niche. “If we don’t go against them, 30 to 50 percent of the farm will be lost,” says Nick. Conventional herbicides are an ecological burden and weeds will soon become resistant to drugs. Biologists say they are only effective for a limited time. Consequently, developing environmentally friendly agents against weeds is a global challenge to ensure food security. Strategies must be found to control agricultural ecosystems in harmony with evolution. Among KIT’s Botanical Institute’s project partners are the Swiss Institute for Organic Agricultural Research (FiBL) and the Weeds 2020 very bad would not recommend shirt Max Planck Institute for Chemical Ecology in Jena.
