KRUPODOROVA T., BARSHTEYN V., KIZITSKA T., RATUSHNYAK V., BLUME Y. (2023): Antagonistic activity of selected macromycetes against two harmful micromycetes. [ascomycetes, Aspergillus niger, basidiomycetes, dual-culture, Penicillium polonicum.] Czech Mycology 75(1): 85-100 (published: 23rd June, 2023)
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.
FAMILONI T.V., OGIDI C.O., AKINYELE B.J., ONIFADE A.K. (2018): Evaluation of yield, biological efficiency and proximate composition of Pleurotus species cultivated on different wood dusts. [edible fungi, nutraceuticals, Pleurotus ostreatus, Pleurotus pulmonarius, Pleurotus “florida”, agro wastes] Czech Mycology 70(1): 33-45 (published: 26th January, 2018)
abstract
Cultivation of edible fungi, notably Pleurotus species, have been considered as alternative food supplement due to their functional qualities. In this study, the effect of different substrates on the yield, biological efficiency and proximate composition of Pleurotus spp. was evaluated. Proximate analysis of the substrates and cultivated mushrooms was carried out using standard methods. Pleurotus ostreatus harvested from Terminalia ivorensis and Triplochiton scleroxylon had the highest yield of 46.97 g and 45.81 g, respectively, with a biological efficiency (BE) of 48.83% and 48.40%, which were significantly different from other mushrooms cultivated on wood dusts.Pleurotus pulmonarius cultivated on T. ivorensis and Gossypium hirsutum had a BE of 43.54 % and 42.28%, which are similar values to the BE of P. “florida” (43.09 %) cultivated on Ceiba pentandra.Pleurotus ostreatus cultivated on Terminalia ivorensis and Alstonia congensis have the highest protein and crude fibre contents of 30.09% and 21.06%, respectively. Pleurotus “florida” harvested from Gossypium hirsutum, Persea americana and T. ivorensis have the highest values of moisture (4.91%), fat (3.96%) and ash (13.98%), respectively, while P. pulmonarius cultivated on Ficus mucuso has a carbohydrate content of 57.66%. The cultivated Pleurotus mushrooms on wood dusts are means of providing foods that are richly endowed with nutritive components, which can be supplemented to low dietary foods to eliminate malnutrition.
Colloquium "Fungi as Model Organisms in Research and Biotechnology", Olomouc, September 14th, 1999. Czech Mycology 52(2): 139-178 (published: 20th April, 2000)
abstract
The colloquium was organized by the joint Commission for Experimental Mycology of the Czechoslovak Microbiological Society and the Czech Scientific Society for Mycology. The purpose of the colloquium was to provide a platform for a broad discussion on the use of fungi as model organisms in both basic and applied research. The programme of the colloquium was divided into four parts dealing with the following topics: phytopathology, biotechnology and ecology, physiology and biochemistry, and medical mycology. Each topic was opened with a plenary lecture (30 min.), followed by short communications (10 min.) and accompanied by poster presentations. Besides four plenary lectures, 15 short communications and 21 posters were presented. In total 38 researchers took part in the colloquium, at who discussed various questions of importance for experimental mycology until late in the evening. Abstracts of the contributions are given here.
