Three degrading white rot fungi, Lentinula edodes (Shiitake mushroom), Trametes versicolor (Turkey Tail mushroom), and Agaricus bisporus (Portobello mushroom) were used to degrade the pharmaceutical drug 17-Ethinylestradiol (EE2). The estrogenic activity of the degradation products was examined using organic extraction assays. They were examined using LC-MS and the Portobello, Turkey Tail, and ...

The production of the button mushroom Agaricus bisporus with mycelium-colonized alginate pellets as an inoculant of the growing medium was investigated. Pellets having an irregular surface and porous internal structure were prepared by complexing a mixture of 1% sodium alginate, 2 to 6% vermiculite, 2% hygramer, and various concentrations of Nutrisoy (soy protein) with calcium chloride. The por...

Mannitol, a six-carbon sugar alcohol, is the main storage carbon in the button mushroom, Agaricus bisporus. Given the physiological importance of mannitol metabolism in growth, fruit body development, and salt tolerance of A. bisporus, the enzyme responsible for mannitol biosynthesis, NADP-dependent mannitol dehydrogenase (MtDH) (EC 1.1.1.138), was purified to homogeneity, and MtDH cDNA was clo...

RNA silencing can function as a virus defense mechanism in a diverse range of eukaryotes, and many viruses are capable of suppressing the silencing machinery targeting them. However, the extent to which this occurs between fungal RNA silencing and mycoviruses is unclear. Here, three Aspergillus dsRNA mycoviruses were partially characterized, and their relationship to RNA silencing was investiga...

With the improvement of quality life, demands on button mushroom (Agaricus Bisporus) increase significantly. But traditional farming methods mainly rely costly human picking, which is currently facing time-consuming and labor-intensive problem. As machine vision technology becomes more mature, harvesting robot with flexible picking end-effector an alternative method to address this issue. Thoug...

This study followed the transmission of 64 segregating genetic markers to 52 haploid offspring, obtained from both homokaryotic and heterokaryotic meiospores, of a cross (AG 93b) of Agaricus bisporus, the commonly cultivated "button mushroom." The electrophoretic karyotypes of the AG 93b component nuclei were determined concurrently (n = 13). Eleven distinct linkage groups were identified by tw...

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...

in this study, quality of white button mushrooms (agaricus bisporus) treated by water and citric acid was evaluated during storage at 2 temperatures (room temperature and 4°c). the effect of modified atmosphere packaging (map, by 4±1% co2, 6±1% o2 and the remaining n2) with or without water absorbent (silicagel) was also evaluated. samples were assessed for their organoleptic properties (textur...
