EXTRACTIVE FERMENTATION OF GIBBERELLIC ACID WITH FREE AND IMMOBILIZED Gibberella fujikuroi
, 2014 Gibberelic acid fermentation using extractive methods was carried out in the presence of corn oil and Alamine 336. Gibberella fujikuroi fungus (NRRL 2278) was used to produce gibberellic acid. Oleyl alcohol was a diluting agent for Alamine 336.

Advanced Materials Technologies, EarlyView.Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

A novel extractive fermentation process for lactic acid
, 1989 In order to produce lactic acid directly with high productivity, we have developed a novel extractive fermentation process combining lactic acid production by two-step pH manipulation and extraction of lactic acid by poly(4-vinylpyridine) resin.

TiO2 as Trap Sensitizer for Enhanced Persistent Luminescence in ZnGa2O4:Cr3+ Nanoparticles
Advanced Optical Materials, EarlyView.Interfacial engineering enables non‐optical charging enhancement in persistent phosphors. By coupling ZGO:Cr nanoparticles with TiO2 through a porous SiO2 interlayer, photogenerated carriers are efficiently transferred and stored in additional trapping states.

Solvent-based approaches to evaluate the ABE extractive fermentation [PDF]
, 2019 The reindustrialization of ABE fermentation is hampered by significant production costs, linked to high product inhibition and limited intrinsic yield. The reduction of these costs depends on the effective application of integrated toxic product removal ...
