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.

Claims

1. A process for the cultivation of mushrooms, which process comprises:

(i) providing a mushroom cultivation substrate;

(ii) inoculating the substrate with mushroom spores or mycelium;

(iii) adding at least one polyene fungicide or a supplement containing at least one polyene fungicide;

(iv) applying conditions to stimulate growth of the mushrooms; and

(v) harvesting the mushrooms.

2. The process according to claim 1 wherein the mushroom spores or mycelium are present on a carrier.

3. process according to claim 1, wherein the polyene fungicide is natamycin, nystatin, lucensomycin or amphotericin B.

4. A process for the cultivation of mushrooms, which process comprises:

(i) providing a substrate for mushroom cultivation comprising at least one polyene fungicide;

(ii) inoculating the substrate with mushroom spores or mycelium;

(iii) applying conditions to stimulate growth of the mushrooms; and

(iv) harvesting the mushrooms.

5. The process according to claim 4 wherein the substrate is a compost based substrate.

6. The process according to claim 4 wherein the mushroom spores or mycelium are present on a carrier.

7. process according to claim 4 wherein the mushroom spores or mycelium are Agaricus or Pleurotus spores or mycelium.

8. process according to claim 4, wherein the polyene fungicide is natamycin, nystatin, lucensomycin or amphotericin B.

9. A process for accelerating the growth of mushrooms comprising:

adding at least one polyene fungicide or a supplement containing at least one polyene fungicide to a mushroom cultivation substrate inoculated with mushroom spores or mycelium, wherein the presence of the at least one polyene fungicide accelerates the growth of the mushrooms.

10. The process according to claim 9 wherein the substrate is a compost based substrate.

11. The process according to claim 9 wherein the mushroom spores or mycelium are present on a carrier.

12. The process according to claim 9, wherein the mushroom spores or mycelium are Agaricus or Pleurotus spores or mycelium.

13. The process according to claim 9, wherein the polyene fungicide is natamycin, nystatin, lucensomycin or amphotericin B.

14. A process for accelerating the growth of mushrooms comprising:

inoculating a substrate for mushroom cultivation comprising at least one polyene fungicide with mushroom spores or mycelium, wherein the presence of the at least one polyene fungicide accelerates the growth of the mushrooms.

15. The process according to claim 14 wherein the substrate is a compost based substrate.

16. The process according to claim 14 wherein the mushroom spores or mycelium are present on a carrier.

17. The process according to claim 14, wherein the mushroom spores or mycelium are Agaricus or Pleurotus spores or mycelium.

18. The process according to claim 14, herein the polyene fungicide is natamycin, nystatin, lucensomycin or amphotericin B.
