Abstract

Black poplar mushroom, Agrocybe cylindracea deserves special attention, due to its medicinal properties. Water and alcohol extracts from fruiting bodies of the fungus have an anti-oxidant, anti-cancer, anti-fungal, cholesterol and triglycerides blood level lowering abilities. This mushroom is rich in proteins and vitamins, mineral elements and low in fat. The aim of the experiments was to determine effect of a substrate supplementation with CaCO3 on mycelial growth, yield, morphological features and storability of fruiting bodies of four strains of A. cylindracea (DC.) Marie. The amount of additive to sawdust substrate affects rate of mycelial growth and yield of investigated strains. A. cylindracea mycelial growth was not affected by addition of CaCO3 to substrate, however a significant effect of this additive was found on yield, which was the highest with CaCO3 addition in an amount of 8 g/100 g of substrate. Carpophores characterized with the largest caps diameter, and the largest individual mass obtained of substrate enriched with CaCO3 addition of 8 g/100 g of substrate. In addition, it was found that supplementation with CaCO3 affect storability of A. cylindracea. The lowest weight loss of fruiting bodies after 3 and 7 days of storage was found with addition of CaCO3 to substrate in an amount of 4 g/100 g of substrate.

Highlights

In nature environment of Poland there are over 4,500 species of macro fungi, with about 1,100 to 1,400 recognized as edible even though there has been considerable research on the taxonomy and phylogeny of these mushrooms, there has been far less research on their domestication (Grzywacz, 2008)
Second part focused on yield, fruiting bodies, morphological features and storage capacity depending on CaCO3 addition
Strain AE02 was characterised by slower mycelium growth, the slowest mycelium growth was stated for strain AE11

Summary

Introduction

In nature environment of Poland there are over 4,500 species of macro fungi, with about 1,100 to 1,400 recognized as edible even though there has been considerable research on the taxonomy and phylogeny of these mushrooms, there has been far less research on their domestication (Grzywacz, 2008). Only less than 10 out of known wild mushroom species around the world have reached large-scale commercial cultivation (Miles & Chang, 2004). Stev) Cyclocybe cylindracea (DC.) (Uhart & Albertó, 2007; Ryman, 2008; Vizzini & Angelini, 2014; Niveiro et al, 2020) and is found on all continents (Watling, 1992). It usually grows in clusters and most often it can be found on old, dead tree trunks and branches of: poplar, willow, elm, ash, elderberry or black poplar (Poppe & Höfte, 1995)
