Article Abstract
In order to better understand the effects of biostimulation and bioaugmentation processes on a marine microbial community, three different mesocosm experiments were planned. Natural seawater (10.000L) was artificially polluted with crude oil (1L) and (1) inorganic nutrients (Biostimulating Mesocosm, BM), (2) inorganic nutrients and an inoculum of Alcanivorax borkumensis SK2 (Single Bioaugmentation Mesocosm, SBM), (3) inorganic nutrients and inoculums of A. borkumensis SK2 and Thalassolituus oleivorans MIL-1 (Consortium Bioaugmentation Mesocosm, CBM). During the experimental period (20days), samples were taken from each mesocosm and the community structure was analyzed by PCR-DGGE. The 16S rRNA gene DGGE banding patterns and sequence analysis demonstrated that biostimulation had the lowest effect on microbial biodiversity in the mesocosms; however, the biodiversity of the marine microbial community dramatically decreased in the CBM (Shannon index was 0.6 in T3). The community structures among the three mesocosms were also markedly different, and major bacteria derived from DGGE bands were related to uncultured Gamma Proteobacteria. The biodegradation results show that the Single Bioaugmentation Mesocosm (SBM) system had the highest percentage of degradation (95%) in comparison to the BM mesocosm (80%) and CBM (70%).

Microbial nitrogen use efficiency (NUE) describes the partitioning of organic N between microbial growth and N mineralization, which is crucial for assessing soil N retention. However, how warming affects NUE along soil depth remains unclear. Based on a whole-soil-profile warming experiment (0 to 100 cm, +4°C) on the Qinghai-Tibetan Plateau, combined with O and N isotope labeling techniques, we determined soil carbon (C) composition, edaphic properties, and microbial parameters.

This review examines the chemical and ecological interactions between filter-feeding mussels and the green macroalga Ulva prolifera in integrated multi-trophic aquaculture (IMTA) systems. Mussels are crucial for nutrient recycling, as they filter water and release bioavailable compounds such as ammonium (NH), urea (CO(NH)), and dissolved organic matter (DOM). These compounds promote Ulva growth and enhance microbial activity.

Estuarine plumes (EPs) are recognized as critical drivers of dissolved organic matter (DOM) heterogeneity in coastal zones, primarily by inducing phytoplankton blooms and subsequent bottom-water dissolved oxygen (DO) depletion. However, the specific mechanisms governing the EP-driven transformations of DOM molecular composition and biogeochemical fate remain elusive. Here, we integrated optical spectroscopy and Fourier transform ion cyclotron resonance mass spectrometry to characterize the molecular signatures of DOM and their biogeochemical transformations within EP-influenced bottom waters of the Pearl River Estuary.

In the present study, cockles were utilized as the raw material to investigate how different salt concentrations and fermentation periods influence the physicochemical indices, microbial community shifts, and volatile flavor components of cockle paste. Through the analysis of volatile flavor substances via GC-IMS, a total of 77 volatile flavor compounds were identified, among which aldehydes accounted for the largest proportion. High-throughput 16S rDNA sequencing was applied to decode the composition of dominant microbiota in the cockle paste samples.

Patients with diabetics usually exhibit disordered glucose and lipid metabolism, as well as disrupted intestinal microecology. Dietary adjustment is essential for controlling diabetes. This study evaluated the ameliorative effects of psyllium-derived medium-molecular-weight arabinoxylan (MMW-AX) on glycolipid biochemical indicators, pathological symptoms, and intestinal microbial diversity in mice with Type 2 diabetes mellitus (T2DM).
