We conclude that the heterogeneously expressed bacterial acdS gene degrades ACC and reduces ethylene-synthesis, eliminating ethylene inhibition on the mycelium growth and primordium formation in A. bisporus-acdS14 transformant was drastically reduced. Being consistent with the AcdS enzyme activity increased by 84%, the mycelium growth rate was increased by 25% but, the ACC and ethylene concentrations were reduced by 71% and 36%, respectively, in the A. bisporus-acdS14 cased with sterilized-vermiculite generated primordia 5 days sooner than wild-type strain, confirming the specific role of the AcdS enzyme. The mycelium eventually produces a pinhead (or primordium), which grows into a new whole mushroom, and the cycle of life continues. For Bekah primordia are concentrated mycelia, both of which are >90. As the mycelium grows and differentiates, it forms primordia (or baby mushrooms) that will grow into a. Heres a look at the debate between mushroom mycelium and fruiting body mushroom. tuoliensis cultivation more tractable and aids efforts to improve P. The identification of such an indicator makes P. UW4 acdS gene, encoding 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (AcdS), into fungus Agaricus bisporus. Mycelium vs fruiting body, the choice is clear. A mycelial CA-asp content of 0.91.2 g/L is thought to indicate physiological maturation and induces primordia formation and fruiting body growth 7. To simplify industrial mushroom cultivation, we introduced a bacterial Pseudomonas sp. There is disclosed a method for growing fruit bodies of Fistulina hepatica which comprises the steps of cutting off some parts of side wall of a cultivation vessel close to the fruit body primordium-forming part on a solid medium contained in the vessel having at least the bottom and side walls to form perforations on the wall, and.
