AI Article Synopsis
- The study investigates the effects of xanthohumol, a compound from hops, on methane emissions from ruminants, which contribute to global warming.
- Using a controlled batch culture system, researchers tested various doses of xanthohumol on a mix of meadow hay and barley meal to measure methane production and microbial activity in the rumen.
- Results showed that even a low dose of xanthohumol (0.1 mg) reduced methane production by 12-13% without affecting rumen fermentation parameters, but further long-term studies are needed to assess its practical use.
Article Abstract
There is a great interest in reducing the methane emission from ruminants as one possible cause of global warming. The aim of the presented study was to determine the effects of xanthohumol, one of the hop (Humulus lupulus) phytofactors, on methane production, microbial population and basic parameters of ruminal fermentation. The experiment was carried out in a batch culture system. The basic substrate (400 mg) consisting of meadow hay and barley meal (60:40) was supplemented with 0 (Control), 0.1, 0.2 or 1.0 mg of xanthohumol. The basic parameters of rumen fermentation and composition of microbial population were measured after 24 h of incubation. For the first time, the results of this in vitro study have demonstrated that xanthohumol is capable to reduce the methane production, even at the lowest dose applied (0.1 mg/400 mg). The observed reduction in methane production by 12-13% was not accompanied by altering the basic rumen fermentation parameters. However, the practical utility of this supplement needs further investigation under long-term in vivo conditions.

Direct methane to methanol conversion is a dream reaction in industrial chemistry, which takes inspiration from the biological methanol production catalysed by methane monooxygenase enzymes (MMOs). Over the years, extensive studies have been conducted on this topic by bioengineering the MMOs, and tailoring methods to isolate the MMOs in the active form. Similarly, remarkable achievements have been noted in other methane activation strategies such as the use of heterogeneous catalysts or molecular catalysts.

Crafting highly dispersed active metal sites on catalysts is an optimal method for improving the catalytic reactivity and stability, as it would improve atomic utilization efficiency, enhance reactant adsorption and activation ability through unique geometric and electronic properties. In this study, two synthesis methods were employed (ammonia evaporation (AE) and the impregnation method (IM)) to load Rh species onto the ZSM-5 support in order to attain tunable dispersivity, during which a 1.25-fold increase in the total yield of liquid oxygenated products (32 433.

ConspectusFor chemical reactions with complex pathways, it is extremely difficult to adjust the catalytic performance. The previous strategies on this issue mainly focused on modifying the fine structures of the catalysts, including optimization of the geometric/electronic structure of the metal nanoparticles (NPs), regulation of the chemical composition/morphology of the supports, and/or adjustment of the metal-support interactions to modulate the reaction kinetics on the catalyst surface. Although significant advances have been achieved, the catalytic performance is still unsatisfactory.
