In contrast, the filtered metabolites of the bacterium do not consume oxygen and allow for less protective intermetallic reprecipitation of hydroxychlorides, increasing the corrosion rate.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download Publication","link":"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0010938X22005741"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2022-09-13","autori":"G.
