Additional evidence of stable EMF-induced changes in water revealed by fungal spore germination
(Informa Healthcare, 1994) Subas Rai; U.P. Singh; G.D. Mishra; S.P. Singh; Samarketu
Spore germination of some fungi was studied in EMF-tieated water samples. Water samples were exposed to 9.575 GHz microwave modulated with square waves of different pulse repetition frequencies. The study indicates varying inhibitory effects of different modulation frequencies on spore germination of Alternaria alternata, A. tenuissima, Fusarium udum, Helminthosorium oryzae, H. turcicumand Ustilago cynodontis. The pulse repetition frequency-dependent variation in spore germination caused by irradiated water illustrates that water may have the capability to store EMF frequency effects. EMF-treated water might have caused the effect by either changing the activities of and/or deactivating the spore enzymes. © 1994 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
Athermal physiological effects of microwaves on a cynobacterium Nostoc muscorum: evidence for EM-memory bits in water
(Kluwer Academic Publishers, 1994) S.P. Singh; Subas Rai; A.K. Rai; S.P. Tiwari; S.S. Singh; Samarketu; J. Abraham
Athermal physiological effects of continuous wave and modulated microwaves were studied on a cynobacterium Nostoc muscorum. The study shows that different microwave frequencies in continuous wave and modulated modes produced significantly different physiological effects on the algae. Water-mediated bioeffects further present additional proof that water has the capability to remember the imposed electromagnetic field characteristics for an extended period of time. © 1994 IFMBE.
Effect of modulated microwave frequencies on the physiology of a cyanobacterium, Anabaena doliolum
(1999) Subash Rai; S.P. Singh; Samarketu; S.P. Tiwari; A.K. Mishra; K.D. Pandey; A.K. Rai
The effect of microwave modulated with square waves of different pulse repetition frequencies was studied on the physiologic behavior of the cyanobacterium Anabaena doliolum. The organism was exposed either directly after inoculating the nutrient solution or indirectly by exposing the nutrient solution before inoculation with the cyanobacterium cells for 1 h to microwave (9.575 GHz) modulated with square wave pulse repetition frequencies of 1000, 700, 500, 200, 100, and 50 Hz at a fixed incident power density (0.658 mW/cm2). This study reveals that microwaves athermally induce different biologic effects, perhaps by changing the structures of water. Modulation frequency-dependent water structures appear to cause the biologic effects by differentially partitioning the ions, altering the rate and/or directions of biochemical reactions, or other mechanisms.

Effect of water's microwave power density memory on fungal spore germination
(Informa Healthcare, 1994) Subas Rai; U.P. Singh; G.D. Mishra; S.P. Singh; Samarketu
The effect of absorbed microwave power in water on germination of some fungal spores was seen. Water samples were exposed to 2.71 GHz microwave at varying incident power density. Incident and absorbed power by water were determined using power sensor and meter. Germination responses of different fungal spores taken from fresh cultures were studied in the microwave power-absorbed-water samples. The study revealed differential germination responses with variation of the absorbed microwave power in water on different fungi. Results indicated that water has the capability to store microwave power alterations. © 1994 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
Synergistic effects of ajoene and the microwave power density memories of water on germination inhibition of fungal spores
(Kluwer Academic Publishers, 1995) Subas Rai; U.P. Singh; G.D. Mishra; S.P. Singh; Samarketu; K.G. Wagner
The synergistic effects of ajoene and the microwave power density memories of water on germination inhibition of some fungal spores are examined. The study reveals power memory varying different synergistic effects of different concentrations of ajoene on the inhibition of spore germination. © 1995 IFMBE.
