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 …

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 …

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. …

Use of Antimycotics, Modified Atmospheres, and Packaging to Affect Mold Spoilage in Dairy Products
The effects of natamycin, oxygen scavengers and a 25% CO₂:75% N₂ modified atmosphere on the growth of <I>Penicillium roqueforti</I> in shredded cheddar and mozzarella cheese stored at 10°C for 0, 60, 120, or 180 day was studied. Microbiological and sensory testing was assessed on 0, 7, 14 and 21 …

Synthesis and function of the conserved motif of mycosamine-containing polyene macrolides
… exhibited fungicidal activity like that of natamycin, another mycosamine-containing polyene macrolide which binds ergosterol and does not permeabilize membranes. Removal of mycosamine from natamycin also abolished its antifungal activity. Collectively, these results led us to conclude that …

Lipid Based Frameworks And Topical Ocular Inserts For The Delivery Of Small Molecule Therapeutics To The Posterior Segment Of The Eye
… formulations. Cationic lipid nanoparticles of Natamycin (NT) were also evaluated. NT SLNs were compared with NT marketed formulation – 5% w/v ophthalmic suspension - in terms of transcorneal permeation and in vivo ocular tissue distribution. Compared to Natacyn® control, transcorneal …

Elucidation of the mycosamine dependent sterol binding and antifungal activities of amphotericin B
… related studies with another natural product, natamycin, we proposed a novel, potentially general, two mechanism model to account for AmB’s potent antifungal activity. These discoveries provide a foundation for the more effective utilization of AmB and demonstrate the capacity of synthetic …

Mechanisms underlying polyene macrolide mediated rescue of growth in ion channel deficient yeast
… assay. We observed no rescue of growth with a Natamycin control (does not form ion channels). In contrast, we observed restored cell growth for Nystatin A1 (optimal at 1 μM), Candicidin (8 nM), and Mepartricin (8 nM). These findings suggest the versatility of trk1Δtrk2Δ homeostatic mechanisms …

Photochemical synthesis of dihydroquinolinones and their investigation toward macrocycle synthesis via ring expansion
… to treat other infectious diseases, for example, natamycin and amphotericin B are used as antifungal agents and ivermectin is used as an antiparasitic agent.1 The synthesis of macrocyclic compounds is typically done using an end-to-end macrocyclization approach. However, challenges arise due to …

Geothermal Resource Assessment of Mississippi
Geothermal energy is exploited through the process of using hot water or steam extracted from reservoirs of geothermal heat in Earth's crust which is derived from the upward convection and conduction of heat from Earth’s mantle and core. This energy can be harnessed to power geothermal heat pumps, …
