Fruiting initiation in mushrooms can be triggered by a variety of environmental and biochemical stimuli, including substances of natural or synthetic origin. In this work ostreolysin, a cytolytic protein specifically expressed during the formation of primordia and fruit bodies of Pleurotus ostreatus, was applied to nutrient media inoculated with mycelium of P. ostreatus, and its effects on myce...

In silico analyses of several laccase promoter sequences have shown the presence of many different responsive elements differentially distributed along the promoter sequences. Analysis of Pleurotus ostreatus laccase promoter poxa1b extending around 1400-bp upstream of the start codon showed the presence of several putative response elements, such as 10 metal-responsive elements. Development of ...

İstiridye mantarının (Pleurotus ostreatus) kültivasyon olanaklarının belirlenmesinde endüstriyel atıklardan iplik fabrikası lif atığı(Tekstil atığı) ve zeytin posasının kullanılma potansiyeli araştırılmıştır. %100 atığı (T), posası(Z) bu atıklara %75, %50 %25 oranlarında meşe talaşı karıştırılarak hazırlanan ortamlarda, misel gelişimi, hasat süresi, toplam zaman, verim biyolojik etkinlik (BE) ü...

Mushroom cultivation has been started recently in Bangladesh. Awareness of the nutritional and medicinal importance of mushrooms is not extensive. In this study, the nutritional values of dietary mushrooms- Pleurotus ostreatus, Pleurotus sajorcaju, Pleurotus florida and Calocybe indica that are very popular among the cultivated mushrooms in Bangladesh have been determined. These mushrooms were ...

Fluorescent pseudomonads isolated from different lesions on caps and/or stipes of cultivated Pleurotus ostreatus were identified as strains of Pseudomonas tolaasii or showed the White Line Assay (WLA) feature of P. ‘reactans’ or were WLA-negative fluorescent Pseudomonas spp. Pseudomonas tolaasii was consistently associated with brown-reddish blotches on P. ostreatus pseudo-tissues, and in the p...

The influences of temperature and nutritional conditions on the mycelium growth of oyster mushroom Pleurotus ostreatus (PO) and Pleurotus cystidiosus (PC) were investigated in laboratory experiment during the summer season of 2014. The results of the experiment indicated that potato dextrose agar (PDA) and yam dextrose agar (YDA) were the most suitable media for the mycelium growth of oyster mu...

Pleurotus ostreatus is a white rot fungus that grows on lignocellulosic biomass by metabolizing the main constituents. Extracellular enzymes play a key role in this process. During the hydrolysis of lignocellulose, potentially toxic molecules are released from lignin, and the molecules are derived from hemicellulose or cellulose that trigger various responses in fungus, thereby influencing myce...

Pseudomonas tolaasii is the main bacterial pathogen of several mushroom species. In this paper we report that strains of P. tolaasii produce volatile substances inducing in vitro mycelia growth inhibition of Pleurotus ostreatus and P. eryngii, and Agaricus bisporus and P. ostreatus basidiome tissue blocks brown discoloration. P. tolaasii strains produced the volatile ammonia but not hydrogen cy...
