Abstract

Agricultural soils especially paddy-fields may be affected by a collection of different stresses including acidity fluctuations. We may see an extremely limited CO2 condition in paddy-field that algal flora must be acclimate with them. Green algae Chlorella, seems a strategic algae with economic and applied point of views. We have no report about this algae in Golestan province especially about possibility of algalization with this algae. Soil samples were collected from paddy-fields of Golestan province during one year. Culturing, purification and preparing unialgal have been done in N8 culture media. Then two steps have been considered for analyzing of behavior of this algae in different acidity and carbon dioxide concentrations. This or short time primitive acclimation the algae were treated at different pHs and GROWTH was measured using turbidity and biomass analysis and pigment including Chlorophyll a, b,b-carotene and xanthophylls were measured in vivo and in vitro after methanolic extraction. At the first step, pH treatments were extremely acidic (pH5), neutral (pH 7), alkaline (pH 9) and extremely alkaline (pH 12). At the second step, combination of pHs and that in all treatment, log phase of GROWTH cure. Results showed that in all treatment, log phase of GROWTH curve occurred in a short time. pH5 caused decline in GROWTH in 3ed day after inoculation. Specific GROWTH rate was significantly higher in limited CO2 conditions. It was noticeable that in all treatments CHLORELLA SP. GHA0013 could adjust the pHs of the medium at optimum condition (pH9.5) using different buffer concentration had no effect on this ability.
