Abstract

There are about 80 species of wild edible mushroom that certainly occur in Brazil and can be used as a natural source of food and medicine. This study aimed to evaluate the in vitro mycelial development in culture media at different temperatures and substrates for cultivation of the edible mushroom species Auricularia fuscosuccinea and Laetiporus gilbertsonii. Additionally, the cultivation and the nutritional composition of A. fuscosuccinea mushrooms were evaluated. The two best wild strains of each species were selected for the in vitro cultivation experiment in two different substrates. Furthermore, an axenic cultivation on sawdust was conduct and the basidiomata produced were evaluated on their nutritional composition. The temperatures that best favored the mycelial growth were 30 °C for A. fuscosuccinea and 25 °C and 30 °C for L. gilbertsonii. The mycelium of both species developed better in the sterile Eucalyptus sawdust substrate. Despite the success in cultivating the mycelium of L. gilbertsonii, it was not possible to obtain basidioma for this species. On the other hand, it was possible to produce basidiomata of the two tested wild strains of A. fuscosuccinea.

巴西两种野生食用菌的驯化研究。

巴西有大约 80 种野生食用菌，可作为天然食物和药物来源。本研究旨在评估在不同温度和基质的培养基中培养食用菌品种 Auricularia fuscosuccinea 和 Laetiporus gilbertsonii 的体外菌丝发育情况。此外，还评估了 A. fuscosuccinea 蘑菇的栽培和营养成分。在两种不同的基质中，每种蘑菇都选择了两种最好的野生菌株进行离体培养实验。此外，还在锯屑上进行了轴向栽培，并对产生的基生菌的营养成分进行了评估。对 A. fuscosuccinea 和 L. gilbertsonii 而言，最有利于菌丝生长的温度分别是 30 ℃ 和 25 ℃。这两个物种的菌丝在无菌的桉树锯屑基质中发育得更好。尽管成功地培养了 L. gilbertsonii 的菌丝，但仍无法获得该菌种的基瘤。另一方面，有可能培育出两种经测试的 A. fuscosuccinea 野生菌株的基原体。

期刊介绍： The Brazilian Academy of Sciences (BAS) publishes its journal, Annals of the Brazilian Academy of Sciences (AABC, in its Brazilianportuguese acronym ), every 3 months, being the oldest journal in Brazil with conkinuous distribukion, daking back to 1929. This scienkihic journal aims to publish the advances in scienkihic research from both Brazilian and foreigner scienkists, who work in the main research centers in the whole world, always looking for excellence. Essenkially a mulkidisciplinary journal, the AABC cover, with both reviews and original researches, the diverse areas represented in the Academy, such as Biology, Physics, Biomedical Sciences, Chemistry, Agrarian Sciences, Engineering, Mathemakics, Social, Health and Earth Sciences.
