Bacterial cellulose biosynthesis in the presence of raw moist olive pomace: A g...
Crugeira, Pedro; Khelifa, Halima; Barreira, Luísa; Halla, Noureddine; Barreiro, Filomena; Rodrigues, Paula; Peres, António M.; Schreiner, Tatiana B.In this study, the biosynthesis of bacterial cellulose (BC) by Komagataeibacter intermedius strain isolated from Kombucha tea in the presence of raw moist olive pomace (MOP) (concentration up to 40 % in the fermentation media) was studied. The BC membranes were characterized by their antioxidant activity, structural character- istics, crystallinity, thermal stability, and mechanical behavior. Using raw MOP acti...
Photoinactivation of sulfate-reducing bacteria using 1,9-dimethyl-methylene blu...
Santos, Gustavo Vital dos; Moura, Hesrom Fernandes Serra; Pedro Jorge Louro Crugeira; Anna Paula Lima Teixeira da SilvaAnnually, 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...
Inactivation of Staphylococcus aureus by antimicrobial photodynamic therapy usi...
Brito Júnior, Anildo Alves de; Crugeira, Pedro; Barbosa, Andressa Vollono; Costa, Wellington Luis Reis; Cangussu, Maria Cristina TeixeiraThe efficiency of antibiotics in terms of their bacterial inhibition is well known. However, studies show that its overuse, underuse, and misuse induce antimicrobial resistance, promoting the need to work with alternative methods. In this sense, antimicrobial photodynamic therapy (aPDT) is a promising selective method demonstrating excellent response. This study aimed to evaluate the antimicrobial action promot...
