Abstract A psychrotrophic marine strain of the ascomycetous yeast Yarrowia
lipolytica (NCYC 789) synthesized silver nanoparticles (AgNPs) in a
cell-associated manner. These nanostructures were characterized by UV-Visible
spectroscopy and scanning electron microscope-energy dispersive spectrometer
(SEM-EDS) analysis. The brown pigment (melanin) involved in metal-interactions
was obtained from the c... hiện toàn bộ

Abstract It is common practice to freeze dry probiotic bacteria to improve their
shelf life. However, the freeze drying process itself can be detrimental to
their viability. The viability of probiotics could be maintained if they are
administered within a microbially produced biodegradable polymer -
poly-γ-glutamic acid (γ-PGA) - matrix. Although the antifreeze activity of γ-PGA
is well known, it ... hiện toàn bộ
