Abstract
Algae represent a diverse group of lower
plants inhabiting various ecosystems. This experiment investigated the impact
of audible sound frequencies on in vitro growth behavior and metabolic
profile of fresh water algae collected from the aquatic ecosystems of Malda
district of West Bengal, India. Four experimental algae species namely Microcystis
sp., Arthrospira sp., Chlorococcum sp. and Cladophora sp. were
subjected to in vitro sound treatments using frequencies of 432 Hz, 1000
Hz and 2500 Hz with loudness level of 30 dB and 60 dB for duration of 2 hours and
4 hours across different experimental set up including control. All the
experimental set ups of algal cultures were monitored where enhancement of both
algal growth and metabolic output were noticed. FTIR studies indicated
modifications in the phenolic contents along with variation in the aliphatic
contents. These findings suggested that specific sound frequencies can serve as
an effective stimulus for optimizing algal growth in vitro and targeted
increase of the selected secondary metabolites.
