W poniedziałek 24 listopada o godz. 14 mgr Jakub Szmytke z Zakładu Fizjologii Bakterii wygłosi seminarium pt. The potential of marine algae: variety of bioactive components, their antibacterial activity and methods of extraction.

Abstract:

The ongoing crisis of antibiotic resistance poses a global threat to public health, and the increasing prevalence of multidrug-resistant bacteria may become one of the leading causes of death in the near future. It is therefore necessary to search for effective alternatives to traditional antibiotics. One promising avenue is metabolites derived from algae, which produce a wide range of bioactive compounds in order to function in the demanding conditions of the marine environment. Many of these compounds have health-promoting properties, including antibacterial, antioxidant, anti-inflammatory and anti-cancer properties. Of particular importance are for e.g. fucoidan, carrageenan and fucoxanthin, which, both in the form of isolated substances and appropriately prepared algae biomass, can be valuable substitutes for antibiotics. In addition, algae are a rich source of macro- and microelements and other nutrients, which makes them attractive additives to feed for farm animals, especially after the withdrawal of antibiotic growth promoters. Not only can they support growth rates and overall animal health, thereby filling the gap left by antibiotics, but they can also enrich feed with vitamins, minerals and other bioactive compounds. The development of effective extraction methods to obtain stable forms, as well as a thorough understanding of their mechanisms of action and determination of the safety of these metabolites, may contribute to the creation of new products that might replace antibiotics and to the production of functional foods and high-value feed additives.
