During of growing of cultures of Arthrobacter sp. KM-P in the medium with concentration 2.5 g/L of pyridine it was fully utilized in 24 hours. It was shown the stability of the process of biodegradation of pyridine with immobilized cells for three consecutive periodic processes. Strain Arthrobacter sp. KM-P is recommended for the treatment of industrial waste water from pyridine.

Internet resource online: 3 blogs and papers on how organisms clean water: I would like to make three points: 1.In these three papers (mentioned in the blog below), the author demonstrated how aquatic invertebrates may contribute to making water clean and clear: https://www.researchgate.net/profile/Sergei_Ostroumov/blog/677_Three_papers_on_filter-feeders_and_their_role_in_ecosystems; 2.In this paper (see the blog below), the same author discovered some new facts on how aquatic plants may contribute to making water clean and removing heavy metals from water: http://blog.researchgate.net/masterblog/594_New_plant_species_as_a_potent_tool_to_clean_water_and_to_remove_heavy_metals; 3.In the opinion paper (see the blog below), the same author integrated various data on plants, animals, and microorganisms toward formulating a new holistic theory of how all organisms interact and benefit each other, and as a community function toward decontaminating water and increasing water quality: http://blog.researchgate.net/masterblog/610_New_unified_theory_of_the_ecological_mechanisms_to_improve_water_quality_and_to_make_water_clear_a_basis_for_water_purification_and_waste_water_treatment;
