Six known metabolites, two new isocoumarins 4 and 8, and one new highly substituted benzoic acid derivative 9 were isolated from the ethyl acetate culture extract of a fungal endophyte, Scytalidium sp. In addition, another new benzoic acid 10 with an unusual 1,2-dicarbonyl side chain was indirectly identified from its methylated derivatives 10a-10d.

Ochratoxin A (OTA) is a widespread mycotoxin calling for the development of effective strategies for its decontamination. In this study, a highly efficient OTA-degrading bacterium Acinetobacter baumannii HAU425 was isolated from soil with ochratoxin α (OTα) as the degradation product. The identification of OTA hydrolase from strain HAU425 was carried out by combining genome mining with gene cloning and heterologous expression technologies.

Timely and accurate on-site detection of ochratoxin A (OTA) is extremely important for global public health. In this study, a fluorescence/colorimetric biosensor based on TiC nano-materials (TiC-NMS) and a machine-learning (ML) based fluorescence/colorimetric intelligent learning system for detection of OTA concentration (COTA) were developed. The sensor was fabricated by functionalizing TiC-NMS prepared by physical-exfoliation assisted metal-ion-induction using ssDNA.

Photoelectrochemical (PEC) is a highly sensitive and fast analytical method that can be used at low concentrations, while photoelectrochromic is a simple and low-cost method primarily utilized for high concentration detection. Therefore, we have developed a dual-signal output sensing platform based on both PEC and photoelectrochromism for rapid and sensitive OTA detection. The sensing platform is divided into signal generation (SG) region and signal output (SO) region, which modified with WO/BiVO photoactive nanocomposites and polyaniline (PANI), respectively.
