Abstract

Experiments were conducted to determine the effect of aeration, light and temperature on growth rate of Acetobacter pel3icles. Bottles containing inoculated pineapple mash were kept under different conditions and readings were taken in terms of height of growth as well as pictures. There was no growth under condition of submerged culture, heavy aeration under fan, low temperature of 10° and 20°C and high temperature of 40°C. The best result was obtained for continuous lighting during normal weather when it is not hot, followed by normal condition and then under dark. During the hot season the best result was obtained under condition of dark, followed by normal and then continuous lighting. The optimum temperature was found to be 25-30°C. The growth in completely closed bottles with no air supply was found to be as good as growth under ordinary room condition. Temperature was found to be the most important factor affecting the growth of nata.
