Killer yeasts as antifungal biocontrol agents
… fungi demonstrating that a substance exhibiting antimycotic properties is secreted during the growth of the two yeasts. The mechanism by which this antimycotic activity was mediated by the yeast <i>Pichia anomola</i> NCYC 750 was identified to be associated with a 27 kDa exoglucanase enzyme. The …

Improved Properties of Natamycin Upon Formation of Cyclodextrin Inclusion Complexes
Natamycin is an antimycotic with very low water solubility and extremely high photosensitivity, which is used to extend the shelf life of shredded cheese products. The objectives of this research are: (a) to find a new delivery system for natamycin, which increases its aqueous solubility and (b) to …

Modulation of the aquaporin-2 localization in renal principal cells
… The second part builds on published work on the antimycotic drug fluconazole, which elicits antidiuretic effects by inducing the AQP2 redistribution to the plasma membrane of renal principal cells in the absence of AVP (Vukićević et al., 2019). The antimycotic drug tebuconazole was identified as …

in vitro studie van Candida albicans en Streptococcus mutans biofilms
… voice prostheses and their susceptibility to antimycotics have been investigated. C. albicans was the predominant yeast species and the isolates showed a uniform sensitivity to nystatin in low concentration. Oral biofilms are known to harbour a great number of different microorganisms. S. …

The Use of Fishery Wastes in the Feeds for Farmed Fish
… trial, propylene glycol was effective as an antimycotic but had a serious, growth-depressing effect, A financial appraisal showed that no significant reductions in the cost of trout feed were possible through the use of semi-moist diets. It is concluded that there is no commercial potential …

Semisynthesis of amphotericin B and its derivatives via iterative cross-coupling
… of amphotericin B (AmB), a potent but toxic antimycotic, has eluded the scientific community. The leading hypothesis involves insertion into the lipid bilayer of fungal cells followed by self-assembly into ion permeable channels that disrupt the transmembrane electrochemical gradient and …

Electronic tuning of site selectivity and semisynthesis of C2'-deoxyamphotericin B
… the improvement of the therapeutic index of this antimycotic and in the development of other antimicrobials that would be refractory to resistance development. AmB is known to self-assemble into ion channels in phospholipid membranes containing sterol. The resulting membrane permeabilization has …

Identification of Volatile Compounds Produced by Brevibacterium Linens that Inhibit Molds
… volatile compounds produced by B. linens for antimycotic activity. A method was developed to quantify inhibition of mold growth and spore germination in the presence of B. linens. The identity of the inhibitory compound was determined. Furthermore, the concentration of the inhibitory compound …

Ensuring the Stability of Natamycin on Shredded Cheese
Natamycin is an antimycotic compound that is widely used in the cheese industry to increase the shelf life of cheeses, especially shredded cheeses, by inhibiting the growth of molds. Natamycin is applied to the surface of cheese as an aqueous suspension or as a powder. However, natamycin is not …

Photodynamic therapy against multidrug-resistant oral strains of Candida spp
… highlights the necessity of creating novel antimycotics that are both effective and safe for systemic health. Within this framework, photodynamic therapy (PDT) may be a viable option for treating yeast infections. In this context, the purpose of this work is to evaluate and compare, through …

Comparative Study of Semisynthetic Derivative of Natamycin and the Parent Antibiotic on the Spoilage of Shredded Cheddar Cheese
The polyene macrolide antibiotic natamycin (Antibiotic A-5283) is commonly used to retard the growth of surface molds on various cheese varieties. Natamycin is commonly applied to the surface of cheese by dipping or spraying, using an aqueous dispersion containing 200 to 300 ppm of the additive. …

Biochemical and structural studies on proteins involved in the production of natural products and degradation of polysaccharides
… With activities including antibacterial, antimycotic, antimalarial, cytotoxic, and immunosuppressive, natural products represent a plentiful source of medically relevant compounds. However, the synthesis of these molecules is often difficult due to their large size and complexity. For …
