Abstract Background The deep mechanisms (deterministic and/or stochastic processes) underlying community assembly are a central challenge in microbial ecology. However, the relative importance of these processes shaping riverine microeukaryotic biogeography is still poorly understood. Here, we compared spatiotemporal and biogeographical patterns using high-throughput sequencing 18S rRNA gene multivariate statistical analyses from subtropical river during wet dry seasons. Results Our results...

Microeukaryoties play key roles in the structure and functioning of marine ecosystems. Little is known about relative importance processes that drive planktonic benthic microeukaryotic biogeography subtropical offshore areas. This study compares community compositions (MCCs) from waters (n = 12) intertidal sediments around Xiamen Island, southern China, using high-throughput sequencing 18S rDNA. work further quantifies contributions spatial environmental variables on distribution MCCs...

Abstract Background Mangrove ecosystems are vulnerable due to the exotic Spartina alterniflora ( S. ) invasion in China. However, little is known about mangrove sediment microbial community assembly processes and interactions under invasion. Here, we investigated co-occurrence networks of archaeal bacterial communities along coastlines Fujian province, southeast Results Assembly overall was driven predominantly by stochastic processes, relative role stochasticity stronger for bacteria than...

Microbial communities are responsible for biological treatment of many industrial wastewater, but our knowledge their diversity, assembly patterns, and function is still poor. Here, we analyzed the bacterial wastewater activated sludge samples taken from 11 full-scale plants (IWWTPs) characterized by same process design different types WWTP compartments. We found significantly diversity compositions assemblages among distinct IWWTPs exhibited a clear species abundance distribution. The...

Insects, such as Hermetia illucens larvae, are rich in chitin and proteins, represent a suitable feed ingredient replacement for animals. However, little is known about the effect of administering H. larvae on intestinal microbiota, bacterial metabolite profiles, mucosal immune status This study aimed to investigate effects colonic microbiota metabolites production finishing pigs. Seventy-two crossbred (Duroc × Landrace Large White) female pigs (initial body weight, 76.0 ± 0.52 kg) were...

Abstract Background With increasing health awareness among consumers, the demand for healthier, tastier, higher quality and nutritional value pork is increasing. It has been shown that different dietary starch sources can alter carcass traits meat quality. However, research on effects of with clear amylose/amylopectin ratio amino acid fatty composition in Longissimus thoracis ( L . ) muscle pigs limited. This study aimed to investigate traits, quality, composition, mRNA expression levels...

Crude oil could affect certain critical microbial processes of nitrogen cycling (N-cycling) in coastal sediments, and disturb the balance. However, understanding effects crude on sediments N-cycling under human disturbance was still limited. In this study, two (named SY HB with heavy slight pollution, respectively) were sampled from Hangzhou Bay, China. After an incubation exposure to different amounts above for 30 days, we found that affected multiple levels. Potential rate measurements...

Multivariate time series (MTS) anomaly detection is a critical task that involves identifying abnormal patterns or events in data consist of multiple interrelated series. In order to better model the complex interdependence between entities and various inherent characteristics each entity, graph neural network (GNN) based methods are widely adopted by existing methods. layer GNN, node features aggregate information from their neighboring nodes update information. doing so, shallow deep...

Bacterial community is strongly associated with activated sludge performance, but there still remains a knowledge gap regarding the rare bacterial assembly and their influence on system performance in industrial wastewater treatment plants (IWWTPs). Here, we investigated communities 11 full-scale IWWTPs similar process designs, aiming to uncover ecological processes functional traits regulating abundant communities. Our findings indicated that was governed by stochastic processes; thereby,...

The present study aimed to investigate the effects of citrus extract (CE) on intestinal microbiota, microbial metabolite profiles, and mucosal immune status in broilers. A total 540 one-day-old yellow-feathered broilers were randomly allotted into three groups fed a basal diet (control group), or containing 10 mg/kg zinc bacitracin (antibiotic CE (CE group). Each treatment consisted six replicates, with 30 per replicate. After 63-day feeding, two replicate selected slaughtered, their ileal...

Abstract This study aimed to assess the efficacy of fermented okara on performance and meat quality, explore feasibility its partial substitution for corn‐soybean meal in pig production. A total 48 pigs (Duroc × Landrace Yorkshire) with an average body weight 58.60 ± 0.65 kg were randomly assigned 2 groups, Control group Fermented (FO) group. There 8 replicate pens each 3 per treatment. fed a basal diet, treatment diet supplemented FO throughout 55‐d experimental period. Results showed that...

Motility is a feature of many pathogens that contributes to the migration and dispersion infectious agent. Whether gentamycin has post-antibiotic effect (PAE) on swarming swimming motility Escherichia coli (E. coli) remains unknown. In this study, we aimed examine whether short-term pretreatment sub-inhibitory concentrations alter E. mechanisms involved therein.After exposure (0.8 μg/ml) gentamicin, was tested in semi-solid media. Real-time PCR used detect gene expression succinate...

This study investigated the effects of citrus extract on growth, carcass and meat quality Duroc × Landrace Large White pigs. One hundred eight pigs (54 barrows, 54 females) were assigned to one three dietary treatments for 138 days. The (1) basic diet; (2) diet supplemented with 75 mg/kg chlortetracycline; (3) (0.25 ml/kg during 56-112 days age 0.20 113-194 age). No significant differences among found growth performance, characteristics, free amino acids (p > 0.05). Feeding tended increase...
