“…By adding a scavenger, the rate constant is significantly reduced due to the reduction of OH radicals in the solution. This study showed that the physical effects at 500 kHz were minimal, and the chemical effects of ultrasound presented the greatest a key role in inactivating the bacteria [67] , [68] , [69] , [70] , [71] , [72] , [73] , [74] , [75] , [76] , [77] , [78] , [79] .…”

“…Also, concluded that hybrid systems such as ultrasonication with UV light and other oxidation processes cannot only enhance but also synergistic increment in the disinfection/inactivation of microorganisms was observed. For instance, Mukherjee and Ahn [67] reported ultrasonic removal of muti-drug bacteria ( Enterobacter sp., Citrobacter freundii , and Klebsiella pneumonia ) load of 6.4 log CFU/mL was 100 % killed in 25 min using Terpinolene as an enhancer. This finding implies that adding a bio-additive to the ultrasonic-activated disinfection process can efficiently eradicate pathogenic multi-drug-resistant bacteria while substantially reduce operating time and cost, making it appropriate to replace conventional wastewater disinfection.…”

The essential oils (EOs) of Myrciaria floribunda (Mflo) and Myrcia sylvatica (Msyl) (Myrtaceae) were obtained by hydrodistillation. The analysis of volatile constituents was performed by GC/MS. Preliminary toxicity was assessed on Artemia salina Leach. The antioxidant capacity was measured by the ABTS•+ and DPPH• radical inhibitory activities. The results indicate that the Mflo EO had the highest yield (1.02%), and its chemical profile was characterized by high levels of hydrocarbon (65.83%) and oxygenated (25.74%) monoterpenes, especially 1,8-cineole (23.30%), terpinolene (22.23%) and α-phellandrene (22.19%). Regarding the Msyl EO, only hydrocarbon (51.60%) and oxygenated (46.52%) sesquiterpenes were identified in the sample, with (Z)-α-trans-bergamotene (24.57%), α-sinensal (13.44%), and (Z)-α-bisabolene (8.33%) at higher levels. The EO of Mflo exhibited moderate toxicity against A. salina (LC50 = 82.96 ± 5.20 µg.mL−1), while the EO of Msyl was classified as highly toxic (LC50 = 2.74 ± 0.50 µg.mL−1). In addition, relative to Trolox, the EOs of Mflo and Msyl showed significant inhibitory effects (p < 0.0001) against the DPPH• radical. This study contributes to the expansion of chemical and biological knowledge on the EOs of Myrtaceae species from the Amazon region.

“…Tetrakis hydroxymethyl phosphonium sulfate (THPS) is a popular green biocide in oilfields which has been found to be effective in mitigating SRB MIC in different systems (Gana et al, 2011;Conlette, 2014;Silva et al, 2021). Biocide enhancers at a small dosage can considerably improve biocide efficacy when used together with biocides (Mukherjee and Ahn, 2022;Xu et al, 2023a;Shi et al, 2023). Peptide A, a chemically synthesized 14-mer circular peptide (cys-ser-val-pro-tyr-asp-tyrasn-trp-tyr-ser-asn-trp-cys) was reported to be an effective biocide enhancer at a sub-ppm (w/w) dosage for THPS in mitigating MIC.…”

To combat abiotic CO2 corrosion of pipelines, chromium steels (CrSs) are used to replace carbon steels, but CrSs can suffer very severe pitting corrosion caused by microbiologically influenced corrosion (MIC) because their passive films are not as good as those on high-grade stainless steels, and their MIC often involves (semi-)conductive corrosion product films. In this study, severe pitting corrosion (2.0 cm/a pitting corrosion rate) with a 7-day weight loss of 3.8 ± 0.5 mg/cm2 (0.26 mm/a uniform corrosion rate) was observed on 13Cr coupons incubated anaerobically with a highly corrosive pure-strain sulfate reducing bacterium (SRB) Desulfovibrio ferrophilus IS5 in 125 mL anaerobic vials filled with 50 mL enriched artificial seawater at 28°C. A popular green biocide, namely tetrakis hydroxymethyl phosphonium sulfate (THPS), was enhanced by biofilm dispersing Peptide A (a 14-mer) to mitigate SRB MIC against 13Cr. The 7-day weight losses for coupons with 50 ppm (w/w) THPS, 50 ppm THPS + 100 nM (180 ppb) Peptide A and 100 ppm THPS were reduced to 2.2 ± 0.2 mg/cm2, 1.5 ± 0.5 mg/cm2, and 0.3 ± 0.2 mg/cm2, respectively. The pitting rates also decreased from 20 mm/a to 12 mm/a, 8.6 mm/a, and 1.5 mm/a, respectively based on the maximum pit depth data for the 7-day incubation. Electrochemical tests using a miniature electrochemical glass cell design supported the weight loss trend with additional transient corrosion rate information. THPS was found to be effective in mitigating severe pitting corrosion on 13Cr, and the enhancement effect of Peptide A for THPS was manifested. This work has significant implications in field applications when CrSs are considered as metal choices to replace carbon steels to combat abiotic CO2 corrosion in pipelines. When SRB MIC is a possible threat, a mitigation plan needs to be implemented to prevent potentially very severe pitting that can lead to pinhole leaks.
