Enhanced corrosion of 2205 duplex stainless steel by Acetobacter aceti through synergistic electron transfer and organic acids acceleration. Bioelectrochemistry 2024; 157:108665. [PMID: 38342073 DOI: 10.1016/j.bioelechem.2024.108665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 01/27/2024] [Accepted: 02/06/2024] [Indexed: 02/13/2024]
Abstract
Acetobacter aceti is a microbe that produces corrosive organic acids, causing severe corrosion of industrial equipment. Previous studies have focused on the organic acid corrosion of A. aceti, but neglected the possibility that it has electron transfer corrosion. This study found that electron transfer and organic acids can synergistically promote the corrosion of 2205 duplex stainless steel (DSS). Electrochemical measurement results showed that corrosion of 2205 DSS was more severe in the presence of A. aceti. Surface analysis indicated a thick biofilm formed on the steel surface, with low pH and dissolved oxygen concentrations under the biofilm. Corrosion intensified when A. aceti lacked a carbon source, suggesting that A. aceti can corrode metals by using metallic substrates as electron donors, in addition to its acidic by-products.

Xu L, Ivanova SA, Gu T. Mitigation of galvanized steel biocorrosion by Pseudomonas aeruginosa biofilm using a biocide enhanced by trehalase. Bioelectrochemistry 2023; 154:108508. [PMID: 37451042 DOI: 10.1016/j.bioelechem.2023.108508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 07/02/2023] [Accepted: 07/08/2023] [Indexed: 07/18/2023]
Abstract
Pseudomonas aeruginosa is a facultative bacterium that is pathogenic. It is ubiquitous in the environment including air handling systems. It causes microbiologically influenced corrosion (MIC) aerobically and anaerobically. In this work, P. aeruginosa was grown as a nitrate reducing bacterium (NRB) in Luria-Bertani medium with KNO3 at 37 °C. Trehalase, an enzyme which plays a crucial role in biofilm formation was found to enhance the treatment of P. aeruginosa biofilm and its MIC against galvanized steel by tetrakis-hydroxymethyl phosphonium sulfate (THPS) green biocide. After a 7-d incubation, 30 ppm (w/w) trehalase reduced sessile cell count by 0.8-log, and it also reduced galvanized steel weight loss by 14%, compared to 2.3-log and 39%, respectively for the 30 ppm THPS treatment. The combination of 30 ppm THPS + 30 ppm trehalase reduced sessile cell count further by 0.1-log and weight loss by 13% compared to using THPS alone. Electrochemical corrosion measurements supported weight loss results. The injection of 20 ppm riboflavin into a 3-d P. aeruginosa broth failed to accelerate the corrosion rate, suggesting that nitrate reducing P. aeruginosa MIC of galvanized steel did not belong to extracellular electron transfer-MIC, because Zn was hydrolyzed after the microbe damaged the passive film.

Shen Y, Dong Y, Zhu H, Dong L. Pseudomonas xiamenensis in the cutting fluids on corrosion behavior of aluminum alloy 2219. Bioelectrochemistry 2023; 150:108350.

Abstract
Aluminum alloy workpieces are prone to black spots and other corrosion problems in the cutting process, which greatly puzzles the machining industry and brings serious losses. However, the cause and mechanism of workpiece corrosion are still unclear. In this study, the effect of P. xiamenensis breeding in the cutting fluid on the corrosion of aluminum alloy 2219 (AA 2219) was studied by corrosion product characterization, biofilm evaluation, corrosion profile, quantitative pit analysis, and electrochemical characterization. The results showed that P. xiamenensis adhered to the surface of AA 2219, forming uneven corrosion product film and biofilm. The state of the film on the surface of the aluminum alloy changed, and pitting corrosion intensified after being immersed in cutting fluid containing P. xiamenensis. The maximum corrosion depths of the coupons were found to be 2.7 μm and 15.8 μm in sterile and inoculated cutting fluids, respectively. The corrosion rate of the aluminum alloy was as high as 9.16 × 10-3 mm/y, which was about 9 times higher than the corrosion rate in the microbial-free cutting fluid. The presence of a P. xiamenensis biofilm accelerated the formation of the water-soluble corrosion product Al(OH)4-, which destroyed the passive film and accelerated pitting corrosion.

The two faces of pyocyanin - why and how to steer its production? World J Microbiol Biotechnol 2023; 39:103.

Abstract
The ambiguous nature of pyocyanin was noted quite early after its discovery. This substance is a recognized Pseudomonas aeruginosa virulence factor that causes problems in cystic fibrosis, wound healing, and microbiologically induced corrosion. However, it can also be a potent chemical with potential use in a wide variety of technologies and applications, e.g. green energy production in microbial fuel cells, biocontrol in agriculture, therapy in medicine, or environmental protection. In this mini-review, we shortly describe the properties of pyocyanin, its role in the physiology of Pseudomonas and show the ever-growing interest in it. We also summarize the possible ways of modulating pyocyanin production. We underline different approaches of the researchers that aim either at lowering or increasing pyocyanin production by using different culturing methods, chemical additives, physical factors (e.g. electromagnetic field), or genetic engineering techniques. The review aims to present the ambiguous character of pyocyanin, underline its potential, and signalize the possible further research directions.

Abstract
Pseudomonas aeruginosa is widely found in industrial water and seawater. Microbiologically influenced corrosion (MIC) caused by P. aeruginosa is a serious threat and damage to the safe service of steel materials. In this study, the MIC behavior of FeCoNiCrMn high-entropy alloy (HEA) by P. aeruginosa biofilm was investigated in the simulated marine medium. The maximum pitting depth of the HEA coupons in the P. aeruginosa-inoculated medium was ~4.77 μm, which was 1.5 times that in the sterile medium. EIS and potentiodynamic polarization results indicated that P. aeruginosa biofilm reduced the corrosion resistance of the passive film of HEA coupons and promoted its anodic dissolution process. XPS and AES results further demonstrated that P. aeruginosa interfered with the distribution of elements in the passive film and significantly promoted the dissolution of Fe.
