“…At the end of the process, Galactomyces (30.82%), Fusarium (26.09%), Scedosporium (12.15%), Microcera (11.48%), Pichia (6.59%), Peziza (6.25%), and Mortierella (1.20%) were detected as the seven most predominant genera (Figure 8). Ohtaekwangia belongs to the proteolytic family Cytophagaceae, and it has been described as a nitricifier, able to produce marinoquinolines, which can provide protection to the rhizosphere from pathogens and predators [63][64][65]. According to Wiegand et al [66], Planctomycetes (Phycisphaera and Algisphaera) plays a crucial role in the carbon and nitrogen cycles, and Phycisphaera has been reported to absorb and hydrolyze heteropolysaccharides excreted by soil microorganisms and degrade wood in marine sediments [67].…”

Annually, the wine industry produces high amounts of waste that can be toxic if disposed of without pretreatment. Vermicomposting is an efficient and low-cost method of decomposing organic matter using earthworms under controlled conditions. The organic substrate used in the vermicomposting process affects microbial populations and reflects the dynamics of enzymatic activity, decomposition of organic matter, and nitrogen transformations. However, the microbiome associations during the whole process are still unexplored. Thus, the aim of the present study was to investigate physicochemical, enzymatic, microbial, and microbiome activities during vermicomposting of winery waste. In this vein, a rectangular vermireactor with Eisenia andrei and Eisenia fetida earthworms, loaded with winery waste, was used. At the end of the process, the carbon/nitrogen (C/N) ratio was decreased, the total nitrogen was increased, the pH was neutralized and excess enzymatic activities were recorded. The bacterial and fungal phyla detected by next-generation sequencing analysis identified Armatimonadetes, Bacteriodetes, Candidatus saccharibacteria, Chloroflexi, Cyanobacteria, Planctomycetes, and Proteobacteria and Ascomycota, Basidiomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, and Mucoromycota, respectively. Physicochemical and microbial changes occurring during vermicomposting of winery waste, along with the microbiome diversity at the beginning and end of the process, may lead to a better understanding of winery-waste biotransformation into effective biofertilizer.

“…The detailed description regarding the preparation of MBS can be studied in our recent work. 45 The main aim of this study includes: (1) removal of ammonia nitrogen at various stages (embedding and acclimation section of MBS (phase I); improvement of the influent load and nitrogen removal capacity (phase II); and efficient and stable operation section (phase III)), (2) analysis of nitrous acid effluent from phases II and III, (3) comparison of respiration activity between acclimated and high-efficiency phases, (4) examining the pH change during the whole experiment, (5) analysis of the nitrification characteristics of MBS in a representative cycle and kinetic degradation. Finally, the microbial morphology and distribution of the MBS were further observed by scanning electron microscopy (SEM).…”

Although toxic and refractory organics, such as phenol and quinoline, are decomposed by anaerobic bacteria, the establishment of specific degrading consortia is a relatively slow process. An anaerobic membrane bioreactor allows for complete biomass retention that can aid the establishment of phenol- and quinoline-degrading consortia. In this study, the anaerobic digestion of phenol (500 mg L) and quinoline (50 mg L) was investigated using an anaerobic baffled ceramic membrane bioreactor (ABCMBR). The results showed that, within 30 days, 99% of phenol, 98% of quinoline and 88% of chemical oxygen demand (COD) were removed. The substrate utilisation rates of the cake layer for phenol and quinoline, and specific methanogenic activity of the cake layer, were 7.58 mg phenol g mixed liquor volatile suspended solids (MLVSS) day, 8.23 mg quinoline g MLVSS day and 0.55 g COD g MLVSS day, respectively. The contribution of the cake layer to the removals of phenol and quinoline was extremely underestimated because the uncounted scoured cake layer was disregarded. Syntrophus was the key population for phenol and quinoline degradation, and it was more abundant in the cake layer than in the bulk sludge. The highly active scattered cake layer sped up the establishment of phenol- and quinoline-degrading consortia in the ABCMBR.
