This study aims to assess the degradation of petroleum products using Chlorella strain algae. To assess the level of petroleum product decomposition by algae based on mass spectrometric detection gas chromatography and to determine the algaes resistance to various concentrations of petroleum products, mineral culture media with different concentrations of diesel fuel (1:10, 1:100, 1:1000) were used for cultivating green algae. Based on the research results, when diesel fuel was diluted with water at a ratio of 1:10, the amount of hydrocarbons detected by gas chromatography was nearly 2.5 times lower than when diluted under the same conditions in the presence of photosynthetic algae. This suggests potential biological degradation. When diluted at a ratio of 1:100, the quantity of these substances did not significantly differ between the control and experimental groups. However, when diluted at a ratio of 1:1000 in the experimental group with algae, the amount of identified hydrocarbons was 17 times higher. Thus, these findings indicate an acceleration in the degradation of petroleum products. The research results under in vitro conditions, focusing on studying the resistance of certain algae to petroleum products at the cellular level, may be utilized in the development of biotechnology for the remediation of water bodies and/or the purification of wastewater from petroleum contamination, particularly diesel fuel. Additionally, these findings could contribute to developing technologies aimed at conducting rehabilitation efforts in freshwater ecosystems contaminated with petroleum products using microscopic algae.
