  • Hybrids of the wild mushroom strain RWK1913
    Publication number: 20040144020
    Abstract: A novel hybrid mushroom culture of Agaricus bisporus, and its inbred and outcrossed descendants, is produced by crossing a culture of a wild strain of Agaricus bisporus designated RWK 1913 with a second culture of a different, preferably cultivated, strain of Agaricus bisporus. Where the second culture is the known cultivated strain designated S130-b, a novel hybrid mushroom culture designated B7970 is formed.

  • Mushrooms
    Patent number: 6655081
    Abstract: A substrate for mushroom cultivation comprises a polyene fungicide, in particular, natamycin. Mushrooms cultivated in such substrates can be harvested earlier than mushrooms cultivated in substrates which do not include polyene fungicides. Alternatively, mushrooms grown in a substrate comprising a polyene fungicide achieve a greater size than mushrooms grown for the same amount of time in a substrate which does not include a polyene fungicide.

  • Microbiological controlled mycoculture nutrient substrates
    Publication number: 20020151037
    Abstract: The present invention is directed to the controlled preparation of mycoculture nutrient substrates and in particular, to methods of composting which include the enzymatic digestion of substrate via colonization with microbial cultures or enzymes. The method of the present invention also include the colonization of substrate with microbial cultures for conferring increased microbial nitrogen content to such substrate. The present invention is further directed to mushroom substrate produced via the methods described herein.

  • Materials for mycoculture
    Patent number: 6298598
    Abstract: The present invention provides improved mushroom cultivation materials which are amenable to improved uniformity of application to mushroom beds. The invention features such materials having particulate indicator therein having a color which is discernable from the organic substrates of the cultivation materials. The application may be followed under incandescent, fluorescent or ultraviolet light or in accordance with other means.
