Effects of mixed microbial fermentation on the quality and metabolite profile of cassava leaf feed based on untargeted metabolomics

open access: yesJSFA reports, EarlyView.
Abstract Background Cassava leaves are a major byproduct of cassava processing and have a low utilization rate. In this study, Lactiplantibacillus plantarum, Saccharomyces cerevisiae, and Bacillus subtilis were used for solid‐state fermentation of cassava leaves to improve their feed quality. Results After 48 h of fermentation, the feed pH decreased to

White and whole wheat flour breads: composition and simultaneous exposure to group B trichothecenes

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The study aimed to determine the profile of group B trichothecenes (TCTBs), to estimate the daily exposure to them and to evaluate the relationship with the composition of different types of sliced wheat bread. A method for simultaneous determination of the TCTBs (deoxynivalenol (DON), 3‐acetyl‐deoxynivalenol, 15‐acetyl ...

Synthesis of Microbial‐Derived Octadecanoids

open access: yesLipids, EarlyView.
C18‐carbon containing dietary polyunsaturated fatty acids (e.g., linoleic acid, α‐linolenic acid, and γ‐linolenic acid) are metabolized by bacteria in the gut into oxygenated lipid mediators termed octadecanoids. To study the biological function of these compounds, we report here the chemical synthesis of multiple octadecanoids.

Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

open access: yesLaser &Photonics Reviews, EarlyView.
A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser

open access: yesLaser &Photonics Reviews, EarlyView.
A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...
