Abstract
Algae are represented by unicellular or multicellular autotrophic thalloid group of plants that are cosmopolitan in occurrence. To study the impact of audible sound on algal growth and physiology four algal specimens were selected for experiment namely Microcystis sp., Arthrospira sp., Chlorococcum sp., Cladophora sp. Three different frequencies were applied viz 432 Hz, 1000 Hz, 2500 Hz and with sound intensity of 30 dB and 60 dB. Selected sound frequencies showed positive effect on the in vitro algal growth along with influencing the biochemical parameters of the treated algae.
