Description

METHOD FOR ACCELERATING GROWTH RATES
1. Field of the Invention
This invention relates to a method for increasing the growth rate of biosystems. More particularly, this invention provides a method for accelerating the growth rates of organisms which involves the use of low energy electrical fields produced by a unique com¬ bination of applied low field strengths and extra-low electromagnetic frequencies .
2. Prior Art The effects of electrical fields on the stimulation of growth and regeneration in various biosystems have been studied. Mcelhaney et al., J. Biomech. 1^:47 (1968) disclose the use of electrical fields to stimu¬ late bone formation. The use of applied magnetic fields to accelerate growth in microorganisms is shown in U. S. Patent 3,871,961. Sewage decomposition pro¬ moting microorganisms are stated in U. S. Patent 3,336,220 to exhibit increased activity after an alter¬ nating electric current was passed through the sewage. MacKenzie in New Scientist, 28 January 1982, pp.
217-220 reports on electrical fields which develop in connection with loss of limbs and which are implicated in the resultant regeneration phenomena. The effects of electrical fields on movement in an amoeba was reported in Science, 187:357 (1975).
Much of the work performed studying the effects of electrical fields on microorganisms has involved the study of mutagenesis and also sterilization, e.g., see Coate, W. B. et al. 1970, "Project Biological Effects Test Program Pilot Studies Final Report." Hazilton Laboratories, Inc., available from NTIS as AD717409, U. S. Patent 3,876,373 and Food Tehnol, 8:361 (1954).
SUBSTITUTE SHEET It is an object of this invention to provide a unique and practical methodology utilizing low energy electrical fields to accelerate growth rates when applied to a living biosyste . It is a further object of this invention to increase such growth rates without producing mutants and without a measurable increase in the temperature of the biosystem. It is a still further object of this invention to provide an energy efficient, low cost and effective process for signifi- cantly reducing the growth cycle time of a biosystem.
DESCRIPTION OF THE INVENTION These and the other objects of this invention are accomplished by a process for accelerating the growth rate of a live organism which comprises disposing the organism in a suitable growth or nutrient medium and subjecting the organism to an alternating electrical field at an electrical field strength and frequency combination which causes the growth rate of the orga¬ nism to increase over the growth rate of the organism when not subjected to the alternating electrical field. The desired increase in growth rate is independent of current density and is exhibited at varying frequencies and electrical field strengths. However, as far as has been tested there appear to exist certain critical fre- quencies, or regions of frequencies, at which acceler¬ ated growth occurs and outside of which there is minimal or no effect. Also at such effective frequen¬ cies there exists a threshold electrical field strength below which there is no effect. It has also been found that, within the ranges of effective frequencies and field strengths, the resultant electrical field is a low energy field which does not produce mutants of the organism; nor is there a measurable increase in the temperature of the biosystem. Furthermore, in the pre- ferred ranges of effective frequencies and strengths there is no electrolysis of the growth medium. It has found that the effective frequencies and voltages are independent of current density. However, there is a practical limitation on current density in that one would not employ currents that adversely affect the biosystem. Tests have been conducted at less than 0.1 mA (milliamp) and it is believed that absolutely no current is required to effectively increase growth rates, so long as effective field strengths and fre¬ quencies are utilized in carrying out the invention.
Definition of Terms
"Growth Rate (rate)" - This is obtained by taking the Klett units over time and calculating the doubling time for the culture. This is done by plotting the Klett unit number of each reading on the log scale of a semi- log graph (wherein the y axis is the semi-log scale and the x axis is time). The slope (m) of the curve is then calculated using the following formula:

Example 1
An overnight exponential culture of prototropic E. coli K-12 (Yale University depository number CGSC No. 4401) growing at 37°C, in L-broth was diluted with thermally equilibrated and sterilized L-broth to a den¬ sity of 1 x 106 cells per milliliter. Portions of this culture were then randomly placed into 10 ml. glass test tubes made of the type glass specified for the colorimeter employed. Each test tube contained two platinum electrodes, spaced 4 centimeters apart, wired in series to a variable frequency generator and in parallel to an oscilliscope, and equipped with means for oxygen input to the growth medium. The tubes con¬ taining the fractionated culture medium were maintained at constant temperature in a thermostatically controlled water bath and each subjected to an electro- motive (EmF) field. Temperature was monitored with a glass/mercury thermometer. Each tube was isolated from the field of the other tubes by brass screening. This brass screening was grounded to totally eliminate any electrical transfer from one tube to the other. The culture densities of each test tube were tested with a Klett-Summerson photoelectric colorimeter by measuring, at 20-30 minute intervals over a 3 hour period, increasing optical absorbences at 660 nanometers. Controls were also run using cells that were inac- tivated by subjecting them momentarily to 60°C and quick cooling to 37°C. Each set of controls consisted of three test tubes which were measured at 10, 100 and 1000 hertz to establish the background of optical absorbence effects due to the electroplating of cells and growth medium components onto the electrodes and also to ascertain any electrolytic effects that might be present. The EmF fields were produced by the variable frequency generator and monitored via the oscilliscope. The low energy fields were applied by passage of alternating current through the growth medium between the platinum electrodes .
The results obtained with EL_ coli , following the above procedure are set forth in the following tables.

Example 4
This example demonstrates the efficacy of the pro¬ cess of the invention in accelerating plant growth rates .
Glass or plastic containers containing soil and bean seeds (Bountiful Green Bush variety of Pinto) were configured for generation of low energy electrical fields in the following four modes:
1. parallel brass screens above and below the soil between which the beans are positioned without touching the screens
2. one brass screen parallel to the side of the container with the seeds spaced apart therefrom with intervening soil in between the seeds and the screen 3. parallel wires in the horizontal plane of the bean seeds and spaced apart therefrom 4. one brass screen at the bottom of the container below the bean seeds.
Each container had from 4-8 bean seeds planted therein. All wires and screens were connected in series to an alternating current generator capable of producing multiple functions (e.g., sine or square waves). For each planted container connected to the generator there was a power-off control container of the same con¬ figuration. All other conditions were the same for controls and test groups. To each test container were applied 22 volts (approximately 2.5 volts/cm. ) at 1 KHz over a period of one week. At the end of the test period the test groups averaged about 8.5 inches in height, whereas the controls had just commenced to ger- minate. The test group had significantly higher ger¬ mination success than the controls. At comparable stages of development the test group was more vigorous in appearance than the controls and hence appeared to exhibit an increase in developmental success.
Example 5
Into a glass container was added a brass screen upon which was placed fruit fly medium containing freshly laid eggs. On top of the medium was placed another screen which along with the screen on the bot- torn of the container, was connected in series with a variable frequency generator. To the test sample was applied a field of IKHz, 22V (about 2.5 V/cm. ) ; the control was a power off sample. The flies (Drosophila melanogaster) were then observed to eclosure (reaching of adulthood) , and observed to show an earlier eclosure in the test sample than the control. The test sample also exhibited a greater hatching and eclosure success and also was more vigorous (i.e., observably signifi¬ cantly more active than the control.)
The foregoing examples demonstrate that 1000 Hz and 10,000 Hz are highly preferred effective frequencies for growth rate acceleration with widely differing spe¬ cies of organisms at field strengths, which can be expressed in terms of volts per centimeter, ranging upwards of from about 1 volt per centimeter to about 22 volts per centimeter at the expressed frequencies. However, positive growth rate acceleration can be achieved at selected frequencies ranging upwards from 10 Hz to about one megahertz (MHZ), the only practical limitation being that point at which mutagenesis occurs. A wide range of field strengths can be employed at each selected effective frequency with a concomitant threshold field strength below which no effect occurs. Again practicality dictates that the upper limit for such field strengths is that point at which a measurable temperature increase occurs in the biosystem. Selection of these critical frequencies and field strengths can routinely be accomplished by per¬ forming a simple series of tests as follows:
Set up electrodes so that electrical field is applied across the biosystem, to which electrodes are applied selected frequencies at a set minimal field strength of IV/cm. Upon discovery of an effective frequency for growth rate increase, various field strengths are applied at the set effective frequency to determine the effective field strength range. With microorganisms it is recom¬ mended that the system be designed essen¬ tially as described in Example 1. With plant or animal species any one of the systems described in Example 4 can be utilized. If no effective frequency is found at 1 volt/cm. , repeat procedure at 5 volts/cm. and at 5 volt increments thereafter until an effective growth rate increasing frequency is found or until a measureable temperature increase occurs in the biosystem using a standard glass mercury thermometer.
Increase of growth rates while improving develop- mental success and vitality of some organisms in accor¬ dance with this invention has important commercial implications for industrial fermentation, as well as, agricultural and pharmaceutical production industries. Improved yields and increased production capacities are direct advantages. Shorter organism growth cycle could open new vistas in diagnostic medicine as well as other areas of medicine such as bone marrow regeneration, organ regeneration, tissue revitilization and the like.

Claims

What is claimed is:
1. A method of increasing the growth rate of a living organism which comprises disposing the organism in a growth medium and subjecting the organism to a low energy electrical field produced by a combined field strength and frequency effective for increasing the growth rate of said organism.
2. The method of claim 1 wherein said field strength is above about 1 volt per centimeter and said frequency is selected from about 10 to about 10*5 Hz.
3. The method of claim 1 wherein said organism is a microorganism or plant or animal.
4. The method of claim 3 wherein said voltage is above about 1 volt per centimeter and said frequency is selected from about 1000 Hz and about 10,000 Hz and the resulting electrical field does not increase the tem¬ perature of the medium.
5. The method of claim 3 wherein said voltage is selected from above about 1 volt per centimeter to about 22 volts per centimeter and said frequency is about 1000 Hz or about 10,000 Hz.
