Fomitopsis Betulina

Eleven 31-methylenlanostane triterpenoids, i.e. seven 21- and four 26-oic acids, as well as a lupane triterpenoid betulin, isolated from the fruiting bodies of the mushroom Fomitopsis betulina were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using cytochalasin-B blocked micronucleus (CBMN) assay. Most of the tested compounds exerted a beneficial effect by reducing DNA damage of human lymphocytes more effectively than amifostine, a radioprotective agent, used as a positive control. All the tested compounds decreased MN frequency in concentration dependent manner, with the concentration of 2.0 ?g mL-1 being the most effective - with increase of the concentration the activity slightly decreases. The structure-activity relationship (SAR) studies indicated that the lanostanes containing a conjugated 7,9 (11)-diene system exhibit lower activity than D8-analogues. It was also demonstrated that the DNA protective activities within the D8-lanostane-26-oic acid group are affected by 3-substitution pattern. In the D8 series the oxygenation at C-12 or 16 as well as 21- or 26-oic acid functionality proved beneficial for in vitro protective effect on chromosomal aberrations. Betulin exhibited the lowest protective activity, but still comparable to that of amifostine.

Fomitopsis Betulina

The antibacterial activity of Fomitopsis betulina cultural liquid (native, native concentrated, lyophilized, dried) against standard bacteria (Escherichia coli АТСС 25922, Pseudomonas aeruginosa АТСС 27853, Staphylococcus aureus АТСС 25923), and clinical isolates (Acinetobacter baumannii 50/1496 MBL, A. baumannii 88/2995 MBL, E. coli 116/3196 KPC, Klebsiella pneumoniae 6/509 ESBL, AmpC, KPC, P. aeruginosa 99/3066 MBL, P. aeruginosa 125/3343 MBL, S. haemoliticus 22/824 MRSA, S. aureus 134/3569 MRCNS) has been evaluated by the serial dilutions method. The antibacterial activity of F. betulina against S. haemoliticus and A. baumannii has been found for the first time. All samples of F. betulina cultural liquid demonstrated the inhibitory effect against standard bacterial strains at the minimum bactericidal concentration (MBC) ranging from >2.0 up to 18.75 mg/ml, and against multidrug-resistant clinical isolates with MBC from 7.8 up to 48.42 mg/ml. The dried F. betulina cultural liquid showed the highest antimicrobial activity against standard bacteria and clinical isolates, except A. baumannii 50/1496 MBL, while native concentrated cultural liquid was the most effective against this pathogen. The study showed that the antibacterial activity of the cultural liquid of F. betulina was improved by concentration and drying. The results obtained indicate that F. betulina cultural liquid contains alternative antimicrobial agents, useful for the treatment of bacterial diseases and might be a perspective substance for the pharmaceutical industries

Fomitopsis Betulina

Ethnomycology is the study of the bio-cultural aspects of human-fungal interactions. This article discusses the involvement of the bracket fungus Fomitopsis betulina within the material culture of traditional games. With a particular focus on the Nordic countries, the aim is to review and analyze the use of simple balls made of bracket fungi. We argue that the fungi ball can be considered the precursor of the rubber (and the gutta-percha) ball. Moreover, the replacement of fungi balls with rubber balls marks, to a certain extent, a temporal transition from traditional folk games with roots in pre-industrial society to modern sports in which balls and other equipment received a more standardized shape.
