Green note compound, such as cis-3-hexen-1-ol, is provided by subjecting linolenic acid and a fresh watermelon foliage to shearing in the presence of an aqueous liquid and yeast. Enzymes within the plant material (i.e., lipoxygenase and hydroperoxide lyase) and the yeast act to cause the linolenic acid to be converted to green note alcohol at a relatively high yield. Green note compound can be provided naturally using a continuous or batch process.

Method for providing green note compounds

This invention relates to a submerged fermentation process for producing high biomass levels of mushrooms mycelia in liquid media suitable for semi-continuous or continuous mushroom spawn production. The process provides a sterile, log phase inoculum for a solid substrate that, when based on biomass, exceeds normal inoculation levels by several thousand fold mycelia substrate production. The liquid inoculum so produced can be aseptically transferred to bulk sterilizer to inoculate a sterilizer grain or sawdust substrate for commercial mushroom production. The liquid inoculum may also be inoculated directly onto the mushroom compost. This invention further relates to microcapsules used to enhance the fermentation process and the equipment used to conduct such process.

Process for production of mushroom inoculum

A process for the in vitro production of chemically modified polyphenolic polymer (PPP). First, stable, highly active extracellular tyrosinase is produced from genetically transformed microorganism such as Streptomyces antibioticus. The tyrosinase is then incubated with a reaction substrate such as 1-tyrosine, hydrolyzed protein, or an oligopeptide in combination with 1-tyrosine. The ratio of the oligopeptide/tyrosine combination as well as variation in the concentration of tyrosinase can be used to modify the color, the molecular size, and the spectral absorbance properties of the PPP produced. Alternatively, or additionally, oxidants such as hydrogen peroxide or hypochlorite can be used to modify the color of the PPP, regardless of the method used to produce the PPP, and the PPP can subsequently be fractionated using molecular weight cut-off ultrafiltration. Organic solvents can also be used in the method of making PPP to produce PPPs having variable but reproducible physical properties.

A process for the in vitro production of chemically modified polyphenolic polymer (PPP). First, stable, highly active extracellular tyrosinase is produced from genetically transformed microorganism such as Streptomyces antibioticus. The tyrosinase is then incubated with a reaction substrate such as l-tyrosine, hydrolyzed protein, or an oligopeptide in combination with l-tyrosine. The ratio of the oligopeptide/tyrosine combination as well as variation in the concentration of tyrosinase can be used to modify the color, the molecular size, and the spectral absorbance properties of the PPP produced. Alternatively, or additionally, oxidants such as hydrogen peroxide or hypochlorite can be used to modify the color of the PPP, regardless of the method used to produce the PPP, and the PPP can subsequently be fractionated using molecular weight cut-off ultrafiltration.
