A substantially microbe-free composition containing plant growth regulators is produced by culturing a fungal spawn on high carbohydrate medium under suitable conditions. The culture filtrate is sterilized, formulated, and used to enhance plant growth.
Claims21
A composition which consists essentially of a sterilized culture filtrate recovered from a culture of the spawn of a Basidiomycete fungus incubated in a medium containing at least 10% available carbohydrate in the presence of long wavelength light, and in the substantial absence of agitation,
- wherein said medium has a BRIX value of 12-15 and further contains potassium ion and carotene, and
- wherein said filtrate is the liquid portion of said culture from which proteins have been denatured and removed, and
- wherein the filtrate has optionally been dried.
A method for preparing a composition containing plant growth regulators, which method comprises
- culturing the spawn of a Basidiomycete fungus in a medium containing at least 10% available carbohydrate in the presence of long wavelength light and in the substantial absence of agitation, wherein said medium has a BRIX value of 12-15 further contains potassium ion and carotene;
- recovering a culture filtrate;
- denaturing soluble proteins in the filtrate and removing said denatured proteins;
- and
- sterilizing the remaining culture filtrate, and
- optionally drying said filtrate to obtain said composition.
