| Popis: | In the present study, an effort has been made to utilize the microalgae Chlorella vulgaris to sequester automobile exhaust gas from a petroleum-based engine of a two-wheeler motorcycle. C. vulgaris was subjected to un-suspended/attached non-enclosure cultivation onto a silicone matrix coated on a stainless steel pipe, protracted to the motorcycle silencer outlet through which the exhaust gas passed out. The automobile exhaust gas contained 13% of carbon dioxide (CO2), 7.5% of carbon monoxide (CO), 0.2% of nitric oxide (NO), 0.08% of nitrogen dioxide (NO2), 0.1% of sulfur dioxide (SO2) and 0.05% of sulfur trioxide (SO3) concentrations, which were removed up to 65%, 59%, 66%, 68%, 65% and 67%, respectively, by C. vulgaris from the attached growth experiment. The present study results showed that the exhaust gases played a crucial role in inducing biomass and lipid yields up to ≥ 3.2 g/L and ≥ 1.1 g/L, respectively. The tolerance of C. vulgaris to the exhaust gas components’ toxicity and its efficiency in treating those gas constituents with simultaneous biomass and lipids yields was better than anticipated in the present study. |
