Photoinactivation of sulfate-reducing bacteria using 1,9-dimethyl-methylene blu...
Santos, Gustavo Vital dos; Moura, Hesrom Fernandes Serra; Crugeira, Pedro Jorge Louro; Silva, Anna Paula Lima Teixeira daAnnually, the oil and gas industry faces equipment losses and product quality degradation due to the presence of sulfate-reducing bacteria (SRB). Given the negative impact of SRB, this study evaluates the use of photoinactivation (PI) with zinc chloride double salt of 1,9-Dimethyl-Methylene Blue (DMMB) as a photosensitizer (PS) in varying concentrations and combined with Laser light at different exposures in an...
Influence of Produced Water and Light Irradiation on the Composition of Exopoly...
Silva, Anna Paula Lima Teixeira da; Soares, Luiz Guilherme Pinheiro; Gulberg, Lars Duarte; Crugeira, Pedro; Almeida, Paulo Fernando deThis study aimed to compare the changes in the composition of the exopolysaccharide (EPS) produced by Lelliottia amnigena in culture medium containing distilled water (DW) and dialyzed produced water (DPW) irradiated by either Laser (λ660 nm, 8.0 J/cm<jats:sup>2</jats:sup>) or LED (λ630 nm, 12.0 J/cm<jats:sup>2</jats:sup>) during bacterial growth using Raman spectroscopy at 1064 nm. The cultures of <jats:italic...
Photodynamic antimicrobial therapy (A-PDT) using 1,9-Dimethyl-Methylene Blue zi...
Soares, Luiz G.P.; Almeida, Cristiane G. de; Crugeira, Pedro Jorge Louro; Nunes, Iago P.F.; Silva, Anna P.L.T. da; Almeida, Jeovana A.Orthodontic treatment involves the use of apparatuses that impairs oral hygiene making patients susceptible to periodontal diseases and caries. To prevent increased antimicrobial resistance A-PDT has shown itself a feasible option. The aim of this investigation was to assess the efficiency of A-PDT employing 1,9-Dimethyl-Methylene Blue zinc chloride double salt -DMMB as a photosensitizing agent combined with re...
Oilfield carbonated produced water recycling coupled to exopolysaccharide trans...
Sampaio, Igor Carvalho Fontes; Ferreira, Joalene de Azevedo Santos; Crugeira, Pedro Jorge Louro; Oliveira, Ian M. da Silva; Santos, Jacson NunesIt was tested the production of a viscous exopolysaccharide (EPS) by Lelliottia amnigena using different concentrations (10, 15, 25, 50 and 100%) of produced water (PW) and Dialyzed PW (DPW) at 100% concentration, with a nutrient medium based on glycerin and sucrose as carbon sources in 44 h batches. There was an increase in EPS recovery when used PW up to a concentration of 25%. The viscosity of the EPS soluti...
Up‐recycling oil produced water as the media‐base for the production of xanthan...
Sampaio, Igor Carvalho Fontes; Crugeira, Pedro Jorge Louro; Ferreira, Joalene de Azevedo Santos; Santos, Jacson NunesProduced water (PW) and crude glycerin (CG) are compounds overproduced by the oil and biodiesel industry and significant scientific efforts are being applied for properly recycling them. The aim of this research is to combine such industrial byproducts for sustaining the production of xanthan by Xanthomonas campestris. Xanthan yields and viscosity on distinct PW ratios (0, 10, 15, 25, 50, 100) and on 100% dialy...
