The effects of biocides on the growth of aerophytic green algae (Chlorella sp.) isolated from a cave environment

Lampenflora communities of bacteria, cyanobacteria, algae, mosses and lichens colonize illuminated show-caves as a consequence disturbances to the caves? ecological equilibrium. These have unesthetic impacts can cause biodeterioration limestone. A 15% hydrogen peroxide solution was proposed for use an agent safe removal these microorganisms. This study tested effects three different biocides (hydrogen peroxide, commercial containing salicylic acid product chlorine dioxide active component), on growth green algae (Chlorella sp.), which are frequently encountered in lampenflora communities. Chlorella sp. treated with under laboratory condition, chlorophyll (Chl a) concentrations were measured 1 h, 3 days, 7 days 10 after treatment. The change Chl concentration compared untreated control group at each time point. All prevented appeared be most effective inhibitor. Hydrogen is known suppress caves, further studies other remain necessary identify that both ecologically economically feasible.
