Micromonospora sp. strain DB620 was isolated from a Wadden Sea sediment sample collected near Büsum (Germany) and is closely related (99% 16S-rRNA gene sequence similarity) to Micromonospora coxensis strain MTCC8093. It produced a new polyene dicarboxylic acid named diacidene (1) and in addition a derivative of chorismic acid, the known 3-[(1-carboxyvinyl)oxy]benzoic acid. The structure elucidation of 1 was achieved by applying different 1D and 2D NMR techniques as well as mass spectrometry and UV spectroscopy.

The occurrence of heat stress in poultry houses is inevitable and leads to oxidative stress in the birds. Lycopene, a natural hydrocarbon carotenoid, possesses potent antioxidant properties. This study aimed to investigate the impact of lycopene on growth performance, meat quality, cecal microflora, and liver metabolome in broilers subjected to heat stress.

Adult acne vulgaris affects up to 43-51% of individuals. While there are numerous treatment options for acne including topical, oral, and energy-based approaches, benzoyl peroxide (BPO) is a popular over the counter (OTC) treatment. Although BPO monotherapy has a long history of efficacy and safety, it suffers from several disadvantages, most notably, skin irritation, particularly for treatment naïve patients.

The slow reaction rates to chemical and photochemical degradation are well-known properties of plastics. However, large plastic surfaces exposed to environmental conditions release particles and compounds that affect ecosystems and human health. The aim of this work was to identify compounds associated with the degradation of polyethylene (PE), polystyrene (PS), and polyvinyl chloride (PVC) microplastics (markers) on silica and sand and evaluate their use to screen microplastics on natural sand.
