“…These results indicate that (1) low-concentration TCH enhanced bacterial and fungal richness at the thermophilic phase, while high-concentration TCH reduced it; (2) the temperaturecooling and mature phases were more conducive to microbial growth; (3) thermal temperature presented a insignificant inhibitory influence on fungal diversity but not bacteria. These conclusions were consistent with previous findings that iproved that low-concentration antibiotics promoted microbial diversity, while high-concentration antibiotics resulted in the opposite effect (Chen et al, 2021a), and fungi have the capacity to tolerate an ill-being environment (i.e., thermal temperature and extreme pH) and re-product (Liu et al, 2021).…”

“…Identical results were obtained in studies, where Ascomycota had always been the dominating phylum among all examined phases and Neocallimastigomycota survived in the temperature-heating phase (Wang et al, 2018). Basidiomycota, which co-occurred in anaerobic conditions and aerobic surroundings (Liu et al, 2021), was higher in the temperature-heating phase during treatment without Cu and TCH and showed richness in the thermophilic phase iduring Cu/TCH-amended treatments. This result at least hints that Cu and TCH promoted Basidiomycota growth in the thermophilic phase.…”

“…Bacteroides shows the capacity to produce an enterotoxin, which could cause watery diarrhea disease in animal and children (Deng et al, 2020;Kheyrodin et al, 2022). Ascomycota and Basidiomycota, as two rich fungal phyla, could tolerate an ill-being environment (i.e., thermal temperature and extreme acid-base property) (Liu et al, 2021;Alavi et al, 2022). Both Neocallimastigomycota and Chytridiomycota were anaerobic fungi, which were only found in the early composting phase (Wang et al, 2018).…”

Synergistic influence on microbial communities ascribed to copper and tetracycline during aerobic composting: Insights into bacterial and fungal structures

There are a considerable number of discussions aimed at analyzing microbial communities and their functions during the composting process. However, microbial succession under copper (Cu) and tetracycline (TCH)-stressed conditions has received less attention. Thus, this work analyzed the bacterial and fungal structures with high-throughput sequencing in Cu/TCH-amended composting (Cu: 0, 100, and 500 mg/kg; TCH: 0, 50, and 300 mg/kg), and the dominating controls on microbial diversity were identified using redundancy analysis (RDA) and structural equation models (SEMs). Low-concentration Cu increased the peak temperature (57°C) at the thermophilic phase. Composting phase-derived changes in bacterial and fungal communities were significant, while Cu and TCH showed a remarkable influence on fungi but not on bacteria. Cu and TCH inhibited Firmicutes' activity while promoting Actinobacteriota growth. Low-concentration Cu and TCH had a negative effect on Basidiomycota in the thermophilic phase and a positive influence on Chytridiomycota in the mature phase. TOC and TN were primary controls on the changes in microbial communities. NH4+-N and NO3--N were more beneficial to fungi with a contribution proportion of 42.13 and 16.85%, respectively. These findings could provide theoretical guidance for the directional research on microbial inoculants.

“…As presented in the rank-abundance curve (Figure 4b), there was an obvious difference between the abundance and uniformity of the microorganisms. As such, the curve of the 10 • C group was relatively smooth with a large horizontal span, indicating the abundance of species composition and the high uniformity of LEW stored at 10 • C. The curve of the 4 • C group was steeper with a small horizontal span, demonstrating the low abundance of microorganisms and a numerical advantage of one or several kinds of microbials [48] in LEW stored at 4 • C.…”

The Quality Analysis and Deterioration Mechanism of Liquid Egg White during Storage

et al. 2022

The quality of liquid egg white (LEW) during storage is critical for the development of the egg industry. In order to effectively control its storage quality, the effects of packaging materials and storage conditions on the quality of LEW were investigated. High-throughput sequencing (HTS) was applied to explore changes in bacterial population proportions and microflora in the spoilage of LEW. The shelf life of LEW packaged with glass (LEW-PG), plastic (LEW-PP), and tinplate (LEW-PT) was preliminarily determined to be 8, 5, and 7 days, respectively. LEW-PG possessed superior sensory scores (65) and L values (87.5), and a lower growth rate of total volatile basic nitrogen (TVB-N) content among the three samples on the last day of shelf life, and was chosen for further study. During 24 days of storage, the sensory scores of the LEW-PG in 10 °C and 4 °C groups decreased by 32.7% and 25.7%, respectively. There was no significant difference in foaming properties of LEW-PG between the 10 °C and 4 °C groups (p > 0.05). HTS analysis showed that the abundance of species composition in the 10 °C samples was higher than that in the 4 °C samples, though the latter possessed a higher community diversity. At the genus level, the dominant bacteria in the 10 °C group were Pseudomonas (21.79%), others (19.21%), and Escherichia (11.21%), while others (37.5%), Escherichia (30.40%), and Bifidobacterium (17.72%) were highly abundant in the 4 °C samples. It is hoped that this study could provide theoretical support for quality control of LEW during storage.

“…Composting is a signi cant measure to achieve organic solid waste (OSW) resources, reduction, and stabilization . Microbial metabolism plays a major role in the high-e ciency, rapid humi cation (Chen et al, 2015;Liu et al, 2021;Lu et al, 2013). Humic substances are ubiquitous natural compounds arising from biological degradation of waste during composting (Khoshnevisan et al, 2021;Lu et al, 2013).…”
