Effects of initial volatile fatty acid concentrations on process characteristics, microbial communities, and metabolic pathways on solid-state anaerobic digestion

Siqi Wang et al.

Summary: Solid-state anaerobic digestion (SSAD) is affected by excessive volatile fatty acids (VFA), such as acetate and propionate. This study investigated the co-effects of VFAs and microbial dynamics under VFA accumulation in pig manure and corn straw SSAD. Mild VFA accumulation was observed when 2 and 4 mg/g acetate or propionate were added, while severe VFA accumulation occurred with the addition of 6 mg/g, resulting in poor methanation performance. The study also revealed the mechanisms of VFA accumulation and its effects on methanogenesis.

Influence of Kazachstania spp. on the chemical and sensory profile of red wines

Mandy Man-Hsi Lin et al.

Summary: This study reports the fermentative traits of two Kazachstania species in red wine and their impact on chemical and sensory properties. The results show that Kazachstania yeast significantly increase acetate esters, particularly phenylethyl acetate and isoamyl acetate, in both Merlot and Shiraz wines, leading to higher jammy and red fruit aroma/flavour compared to wines fermented with Saccharomyces cerevisiae alone. The study highlights the potential of Kazachstania yeast as starter cultures for improving the aromatic complexity of red wines.

Fungal dynamics and potential functions during anaerobic digestion of food waste

Xingsheng Yang et al.

Summary: This study investigated fungal succession and their ecological and engineering value in anaerobic digestion (AD) systems using food waste. The results showed that fungal biomass and diversity followed a similar pattern, decreasing from the initial time point and then rising and stabilizing. The dominant fungal taxa had the potential to degrade complex organic matter and alleviate fatty acid and ammonia accumulation. The fungal community structure and composition changed during the AD process, and the assembly succession was mainly determined by environmental changes. AD bioreactors could select specific fungal taxa over time, but function prediction based on existing databases may underestimate fungal function. Overall, fungi have important ecological and engineering values in AD systems.
