Electromagnetic waves are used in today lives and spreading the environmental factor. We need visible light to see, radio waves for telecommunication and x-ray for medical purpose. Electromagnetic radiations are used for its bactericidal effect. It affects the cellular mechanism, cell membrane and might increase or decrease the activity of protein. The species selected for study was Lactobacillus rahmnosus (MTCC 1423) and Lactobacillus plantarum (MTCC 9496). Lactobacillus is friendly type of bacteria that lives in our digestive system, urinary tract and used to treat many skin disorders as blisters, canker sores, acne. The culture were exposed to three different frequencies (7.50GHz, 7.62GHz, 6.41GHz) with four different time intervals 5mins, 10 min, 15min, 20min. For the growth test MRS agar used and serial dilution were made to 10-3 and 10-4. The result showed the significant decrease in the number of colonies (cfu/m) with increasing time and frequency, where as the antibiotic sensitivity test, antibiotics were Kanamycin (K30), Gentamicin (G50), Tetracycline (Te30), Norfloxacin (NX10) among all four antibiotics Norfloxacin (NX10) showed the maximum zone of inhibition and rest all have shown the random changes may be because of the activity of protein. The result of biochemical showed negative effect of electromagnetic radiation on Lactobacillus species.
If you simply do not want to quit dairy, despite the high calcium contenct, homemade raw yoghurt is an option. I'm not an expert so do your own research and proceed at your own risk. The following is what I personally do:
Starter yoghurt culutre
device that can hold constant temperature at around 100℉ or 38°C
The temperatue should be constant and the amount of time it takes depends on the particular situation. I frequently check on the thickness and stop at the desired thickness.
Great with local apples and a little bit of local honey. Enjoy!
