Enhanced production of sabinene by engineered Saccharomyces cerevisiae from corn hydrolysates.

Sabinene is a type of monoterpene that is widely used in flavors, fragrances and pharmaceuticals. Though sabinene biosynthesis has been investigated in a variety of microorganisms, application of sabinene is still limited due to its high production cost and lesser yielding strains. The baker's yeast Saccharomyces cerevisiae, which is generally recognized as safe (GRAS), is a suitable cell factory for the food and beverage industries.

No Meta-analytic Evidence for Risks due to Prenatal Magnetic Resonance Imaging in Animal Models.

Background: Magnetic resonance imaging (MRI) is a powerful, noninvasive tool for both clinical practice and research. Though the safety of MRI has been endorsed by many professional societies and government bodies, some concerns have remained about potential risk from prenatal MRI. Case-control animal studies of MRI scanning during gestation and effects on offspring are the most direct test available for potential risks.

Structural Characterization, Antioxidant and Antitumor Activities of the Two Novel Exopolysaccharides Produced by DH-1.

Exopolysaccharides produced by edible microorganisms exhibit excellent constructive physicochemical and significant biological activity, which provide advantages for the food or pharmaceutical industries. Two novel exopolysaccharides produced by DH-1 were characterized, named S1 and S2, respectively. S1, with a molecular weight of 34.
