TECHNOLOGY FOCUS - BIOLOGY - Preferred Microorganisms: The fermentation is achieved with a yeast selected from Saccharomyces sp., Schizosaccharomyces pombe, and/or Kluyueromyces sp. (preferably Saccharomyces sp.); or a bacterium selected from Clostridium sp., Zymomonas sp., Spirochaeta sp., Erwinia amyloyora, Leuconostoc mesenteroides, Streptococcus lactis, and/or Sarcina ventriculi (preferably Zymomonas sp.). Preferred Method: The combination of monoterpene and surfactant is added to the fermentation medium in greater than or equal to 2 increments during the fermentation. The combination of monoterpene and surfactant is added to the fermentation medium before inoculation with the microorganism; during the first one-third of the fermentation; during the middle one-third of the fermentation; and during the final one-third of the fermentation. The emulsion comprising the monoterpene and the surfactant is added to the fermentation medium in an amount of (0.1-1000, preferably 1-100) ppm, by weight. The fermentation medium contains essentially no sugars derived from orange peels. The feedstock substrate contains essentially no monoterpene before adding the emulsion of monoterpene and surfactant.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The surfactant has a hydrophile-lipophile balance (HLB) value of (7-25, preferably 9-18, especially 11-16); and is selected from ethoxylated alcohols, ethoxylated carbohydrates, ethoxylated vegetable oils, ethoxylated amines, fatty acids, ethoxylated fatty acids, fatty amides, and fatty diethanolamides (preferably compound(s) selected from 23 compounds as given in the specification e.g. oleyl alcohol 10 ethylene oxide (EO), Tween 20 (RTM: non-ionic surfactant), dipropyleneglycol methyl ester, sodium lauryl sulfate, castor oil 80 EO, castor oil 30 EO, Dowanol DB (RTM: diethylene glycol monobutyl ether), Tergitol NP6 (RTM: non-ionic surfactant), dipropyleneglycol methyl ester, sodium xylenesulfonate). Preferred Composition: The combination of monoterpene and the surfactant is in the form of a solution, solid, or emulsion (preferably oil-in-water emulsion). The emulsion comprises the monoterpene (1-70, preferably 2-20, especially 3-15) wt.%, the surfactant (0.2-25, preferably 1-20, especially 2-10) wt.%), and water (balance).    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The surfactant is selected from polyethyleneglycols (PEG), polypropylene glycols (PPG), and monoesters and diesters of PEG and PPG (preferably PEG 400 dioleate). WIDER DISCLOSURE - Also disclosed is method for improving production of non-terpene organic compound by microorganism in fermentation medium, involving: adding to the fermentation medium a combination of a terpene and a surfactant, to increase rate and/or yield of production of non-terpene organic compound.    SPECIFIC COMPOUNDS - 6 Compounds are specified as the monoterpene e.g. pinene, nerol, cetral, camphor, and limonene of formula (I).    EXAMPLE - An emulsion was prepared by first dispersing surfactant in water, followed by addition of terpene with vigorous mixing. The emulsion contained (wt.%) d-limonene (3), hexadecane (4), castor oil 30 ethylene oxide (EO) (5.7), polyethylene glycol (PEG) 400 dioleate (2.7), and water (balance). The emulsion was then evaluated for improvement in utilization rate of sugar in a yeast fermentation of glucose. D-glucose (5 g) was dissolved in tap water (45 g), Muntons dry brewers yeast (0.4 g) was then added, and this mixture was allowed to mix for 30 minutes in presence of air. The sugar/yeast/water mixture was then taken up in a 60 ml syringe with 1 cc of airspace and lightly capped. This procedure was repeated 3 times except that the composition was added to the mixture just prior to taking the mixtures up in the syringes in amounts of 20, 50 and 100 ppm by weight. The syringes were allowed to sit undisturbed for 78 hours at room temperature. After 78 hours, a portion of the mixture in each syringe was withdrawn and filtered through 25 mm syringe filter (5 micron) formed from Teflon (RTM: polyethyleneterephthalate) and percent dissolved solids (Brix) were determined as a measure of the amount of sugar in the mixture. The sugar remaining in fermentation at 78 hours as % Brix at start/% Brix at 78 hours, at 0, 20, 50 and 100 ppm of the emulsion was 9/5.4, 9/5.4, 9/5 and 9/4.8, respectively. The data showed that the presence of the emulsion composition resulted in increased sugar utilization by yeasts at 50 and 100 ppm levels. A 46.6% sugar conversion was seen in the sample containing 100 ppm of the terpene/surfactant composition compared with 40% conversion in the blank.
