In vitro photodynamic therapy of Candida albicans, the cause of vulvovaginal candidiasis, is enhanced by Bacillus and Enterococcus probiotics.

Background: Candida albicans is the primary cause of vulvovaginal candidiasis, a worldwide health concern for women. The use of supplemental methods, such as antimicrobial photodynamic therapy (aPDT) and probiotics, was promoted by the ineffectiveness of the existing antifungal drugs.

Escherichia coli enhances the virulence factors of Candida albicans, the cause of vulvovaginal candidiasis, in a dual bacterial/fungal biofilm.

Co-infection with other microorganisms can promote the Candida albicans to be invasive. In this study, Escherichia coli and C. albicans were co-isolated from the women with candidiasis symptoms.

Co-immobilized spore laccase/TiO nanoparticles in the alginate beads enhance dye removal by two-step decolorization.

Combinatorial application of different dye removal methods with specific features can lead to a novel and robust decolorizing system. In this study the bacterial spore laccase and TiO nanoparticles were co-entrapped to enhance dye degradation. The optimum entrapment conditions were achieved in the presence of alginate 2% (w/v) and Ca (0.

Microbial cell lysate supernatant (CLS) alteration impact on platinum nanoparticles fabrication, characterization, antioxidant and antibacterial activity.

Microbial mediated biological synthesis of nanoparticles is of enormous interest to modern nanotechnology due to its simplicity and eco-friendliness. In the present study, a novel green method for the synthesis of platinum nanoparticles (PtNPs) has been developed using bio-derived product-cell lysate supernatant (CLS) from various microorganisms including Gram-negative bacteria: Pseudomonas kunmingensis ADR19, Psychrobacter faecalis FZC6, Vibrio fischeri NRRL B-11177, Gram-positive bacteria: Jeotgalicoccus coquinae ZC15, Sporosarcina psychrophila KC19, Kocuria rosea MN23, genetically engineered bacterium: Pseudomonas putida KT2440 and yeast: Rhodotorula mucilaginosa CCV1. The biogenic PtNPs were characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared (FTIR), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM), and atomic force microscopy (AFM).

Exploring the potentials of halophilic prokaryotes from a solar saltern for synthesizing nanoparticles: The case of silver and selenium.

Halophiles are the organisms that thrive in extreme high salt environments. Despite the extensive studies on their biotechnological potentials, the ability of halophilic prokaryotes for the synthesis of nanoparticles has remained understudied. In this study, the archaeal and bacterial halophiles from a solar saltern were investigated for the intracellular/extracellular synthesis of silver and selenium nanoparticles.

Laccase mediator system obtained from a marine spore exhibits decolorization potential in harsh environmental conditions.

Laccases play a significant role in remedying dye pollutants. Most of these enzymes are originated from terrestrial fungi and bacteria, thus they are not proper to be used in the environments with neutral/alkaline pH, or they may require laborious extraction/purification steps. These limitations can be solved using marine spore laccases through high stability and easy to use application.

Z-Scan and Absorption Study of Crocin and Rhodamine B Decolorization by Bacterial Laccase.

Dye decolorization is currently measured by the reduction of dye absorption, based on its linear optical properties in solution. However, this method is not suitable for high dye concentrations with linear attributes in the absorption spectra. In this work, nonlinear optical properties are used to study dye decolorization of Crocin and Rhodamine B treated with a bacterial laccase.
