Influence of development conditions on qualitative indicators of Fungus Chaga

Abstract

The paper gives description of the growth conditions on the output of valuable components from the fungus chaga. The samples of chaga represent two different regions of Eurasia – Western Siberia and the Czech Republic. The results of the research proved that the yield of melanin in water extracts from the chaga grown in Western Siberia was 1.7% higher than that of the Czech analogue. Consequently, the authors concluded that the harsher conditions of growth, which cause a slow growth of the fungus, lead to a greater accumulation of useful substances.

Chaga mushroom triterpenoids as adjuncts to minimally invasive cancer therapies: A review

“…For instance, Chaga mushroom from Normandy (northern France) was found to contain more betulin and betulinic acid, but less inotodiol when compared to their Canadian counterparts ( Géry et al, 2018 ). Harsh growth conditions and environmental stress were shown to increase triterpenoid concentration and diversity while cultured Chaga mushroom mycelia in a medium consisted of fewer bioactive compounds ( Zheng et al, 2007 , Razumov et al, 2019 ).…”
