Abstract

Competition between 31 macromycete species and two harmful micromycetes Aspergillus niger and Penicillium polonicum was evaluated using dual-culture plate assay. All investigated fungi, except for Inonotus obliquus and Lepista luscina, possessed different levels of antagonistic activity against the tested micromycetes. Hypsizygus marmoreus and Lyophyllum shimeji were inactive against A. niger. Morchella esculenta and Oxyporus obducens were passive in the case of co-growth with P. polonicum. The study of fungal interactions showed variability in types of reactions and level of their visualisation. Co-cultivation of the studied species resulted in the following reactions: deadlock after mycelial contact and at a distance, partial or complete replacement after initial deadlock on contact. In general, the studied macromycetes showed moderate activity against the two micromycetes, as 11 species showed active and 7 species moderate antagonism. Results revealed higher antagonistic activity of macromycetes against P. polonicum than in A. niger co-cultures. Wood-decaying species Ganoderma lucidum and Trametes versicolor were the most active fungi against the two tested micromycetes with a maximal antagonism index. These findings provide valuable insights which can be further explored by means of in vivo assays to find a suitable agent for the biocontrol of diseases or spoilage caused by A. niger and P. polonicum.

选定的大型真菌对两种有害的微型真菌的拮抗活性。
采用双培养平板法对31种大型真菌与两种有害微真菌黑曲霉和波兰青霉菌的竞争进行了评价。除Inonotus oblixus和Lepista luscina外,所有研究的真菌对测试的微菌都具有不同水平的拮抗活性。海绵藻和石梅子对黑曲霉无活性。羊肚菌和Oxyporus obducens在与P.polonicum共生长的情况下是被动的。对真菌相互作用的研究表明,反应类型和可视化水平存在差异。研究物种的共培养导致以下反应:菌丝体接触后和一定距离处的死锁,接触时初始死锁后的部分或完全替换。总体而言,所研究的大型真菌对这两种微真菌表现出中等活性,其中11种表现出活性,7种表现出中等拮抗作用。结果表明,与黑曲霉共培养物相比,大型真菌对P.polonicum的拮抗活性更高。木腐菌灵芝和云芝是对两种微菌最具活性的真菌,拮抗指数最高。这些发现提供了有价值的见解,可以通过体内测定来进一步探索,以找到一种合适的生物控制黑曲霉和P.polonicum引起的疾病或腐败的试剂。

期刊介绍: Czech Mycology (former "Česká Mykologie") is an peer-reviewed international scientific journal publishing papers in all aspects of mycology including taxonomy, ecology, physiology and mycofloristics as well as mycological topics in forestry, agriculture and medicine. Czech Mycology publishes full length papers and short communications reporting original research which make a significant contribution to mycology. Review articles are also published.
