Cytotoxicity evaluation and metabolomic profiling of Spheciospongia vagabunda-associated fungi corroborated by in silico studies Open
Cancer incidence continues to increase every year. Scientists strive to search for new anticancer compounds to combat this disease. Appealingly, marine environmental niches are still an untapped scaffold for natural products with chemical …
Wastewater-borne pollutants influenced antibiotic resistance genes and mobile genetic elements in the soil without affecting the bacterial community composition in a changing wastewater irrigation system Open
Over decades, untreated wastewater from México City was used to irrigate crops in the Mezquital Valley. With the construction of a wastewater treatment plant (WWTP), irrigation was replaced by WWTP effluent. To investigate how this shift a…
Transition from irrigation with untreated wastewater to treated wastewater and associated benefits and risks Open
Investments in “Clean water and sanitation” drive a transition from irrigation with untreated to irrigation with treated wastewater. While this transition reduces many health risks, it may decrease crop yields, and soil carbon storage, cau…
Downstream effects of the pandemic? Spatiotemporal trends of quaternary ammonium compounds in suspended particulate matter of German rivers Open
During the SARS-CoV-2 pandemic, the preventive use of antimicrobials such as quaternary ammonium compounds (QACs) surged worldwide. As cationic and surface-active biocides, QACs are only partly removed during wastewater treatment and may c…

Bioactivity of crude extract produced by endophytic fungi isolated from Ziziphus spina-christi (Nabq) leaves for antimicrobial evaluation as well as optimization of culture medium conditions Open
Twenty fungal endophytes were isolated from Nabq, and plug diffusion screening revealed four of those isolates to be promising. These isolates were identified molecularly as Aspergillus sp. of Sect. Flavi (ZSEFL2) and Sec. Niger (ZSEFL14),…
Organic and conventional farming systems shape soil bacterial community composition in tropical arable farming Open
Soils present a limited resource for agricultural production and bear a vast diversity of organisms crucial for crop health and the provision of ecosystem services. There is growing evidence that agricultural practices affect soil microbia…
Nitrogen use efficiency of microalgae application in wheat compared to mineral fertilizer Open
Background Wastewater from sewage treatment plants contains high levels of nutrients, which can be used for plant nutrition. Classical wastewater treatment plants use complex microbial consortia of autotrophic and heterotrophic microorgani…
The anti-infective potential of the endophytic fungi associated with <i>Allium cepa</i> supported by metabolomics analysis and docking studies Open
Endophytic fungi are known to be a rich source of anti-infective drugs. In our study, Allium cepa was investigated for fungal diversity using different media to give 11 isolates which were identified morphologically. Out of the isolated fu…
Genomic plasticity and adaptive capacity of the quaternary alkyl-ammonium compound and copper tolerant Acinetobacter bohemicus strain QAC-21b isolated from pig manure Open
Here, we present the genomic characterization of an Acinetobacter bohemicus strain QAC-21b which was isolated in the presence of a quaternary alky-ammonium compound (QAAC) from manure of a conventional German pig farm. The genetic determin…

Insights into the impact of manure on the environmental antibiotic residues and resistance pool Open
The intensive use of antibiotics in the veterinary sector, linked to the application of manure-derived amendments in agriculture, translates into increased environmental levels of chemical residues, AR bacteria (ARB) and antibiotic resista…

Formation of specific bacterial assemblages on sterile polyethylene microplastic particles added to a marine aquaria system Open
Microplastics (MP) represent an anthropogenic surface for bacterial colonization in marine ecosystems. In order to determine if MP act as vectors of specific bacterial communities, which might include non-native and potential pathogens for…

Pseudocitrobacter corydidari sp. nov., isolated from the Asian emerald cockroach Corydidarum magnifica Open
A Gram-negative bacterial strain, G163CM T , was isolated from the gut of the Asian emerald cockroach Corydidarum magnifica . The 16S rRNA gene sequence (1416 bp) of strain G163CM T showed 99.22% similarity to Pseudocitrobacter faecalis CC…

Isolation of Hermetia illucens larvae core gut microbiota by two different cultivation strategies Open
Hermetia illucens larvae (black soldier fly larvae, BSFL) convert efficiently organic waste to high quality biomass. To gain knowledge on the specific functions of gut microbes in this process it is a prerequisite to culture members of the…

Description and comparison of the skin and ear canal microbiota of non-allergic and allergic German shepherd dogs using next generation sequencing Open
Atopic dermatitis is one of the most common skin diseases in dogs. Pathogenesis is complex and incompletely understood. Skin colonizing bacteria likely play an important role in the severity of this disease. Studying the canine skin microb…
Acinetobacter stercoris sp. nov. isolated from output source of a mesophilic german biogas plant with anaerobic operating conditions Open
The Gram-stain-negative, oxidase negative, catalase positive strain KPC-SM-21 T , isolated from a digestate of a storage tank of a mesophilic German biogas plant, was investigated by a polyphasic taxonomic approach. Phylogenetic identifica…
