Expansion of Deltaproteobacteria diversity from marine sediment reveals unique metabolic features
… we obtained hundreds of unique, uncultured metagenome-assembled genomes (MAGs) from a variety of coastal and deep-sea sediments. These 402 Deltaproteobacteria MAGs represent a 28% increase in Deltaproteobacteria genomes. Phylogenomic analyses revealed 12 novel lineages which consist entirely …

Molecular characterization of microbial communities in small-scale biodigesters using whole genome shotgun metagenomic approach
… data from metagenomic reads, contigs, and metagenome-assembled genomes (MAGs) can achieve a more comprehensive understanding of microbial taxonomy and functional capabilities in biodigesters. This study investigates the microbial communities in small-scale biodigesters, using taxonomic data …

Shotgun metagenomics exploration of fermented food microbiomes
… the effect of read depth on the recovery of Metagenome Assembled Genomes (MAGs), revealing that specific genome coverage is the most important factor in terms of the likelihood of recovering a particular MAG.

Population genetics of the endemic red-chested sea cucumber, Hemiocnus insolens, along the southern coastline of Africa
… regions (Sanger sequencing) as well as their metagenomes (Oxford Nanopore Technologies). ChromasPro and seaview.exe were used for sequence analysis and tree building, respectively. MGnify and Flye were used for assessing the metagenomics of selected samples. Parsimony-based tree fitting was …

Metagenomic approaches for examining the diversity of large DNA viruses in the biosphere
… first chapter of the thesis, I investigated 11 metagenome-assembled genomes (MAGs) of giant viruses previously surveyed from Station ALOHA in the Pacific Ocean. St. ALOHA is located near Hawaii and represents oligotrophic gyres which the majority of the ocean is made of them. I focused on 11 …

Applying molecular methods to investigate potential anthropogenic impacts on ageing in a free-living bat species
… the gut microbiome of bats from both colonies. Metagenome assembled genomes (MAGs) were reconstructed and functionally annotated to assess taxonomic composition, diversity and inferred metabolic capacity. Despite high interindividual variability, there were no clear diAerences in overall …

Community Composition and Function of the Hindgut Microbiome in Seaweed-Eating Marine Fish
… acid and vitamin metabolism. Analyses used 397 metagenome-assembled genomes (MAGs) and metatranscriptomes from K. sydneyanus collected from waters near Great Barrier and Little Barrier islands, New Zealand. Most bacteria (99%) were unclassified at the species level, and Bacteroidia and …

Microbiology of the sulfur-dominated glacial ecosystem at Borup Fiord Pass, and high Arctic low-temperature spring associated microbial mats, The
… data was carried out and produced 31 reportable metagenome assembled genomes (MAGs), which revealed that sulfur oxidation may be a cosmopolitan process at BFP. Overall, results suggest that while sulfur cycling organisms dominate during acute events, a basal community structure appears to …

Metagenomic analysis of the biodiversity and seasonal variation in the meromictic Antarctic lake, Ace Lake
… community were studied using a time-series of metagenomes utilizing the Cavlab metagenome analysis pipeline. Statistical analyses of taxa abundance and environmental factors revealed the effects of the polar light cycle, with 24 hours of daylight in summer and no sunlight in winter, on the …

Prokaryotic diversity and ecosystem functioning in hypersaline environment: a metagenomic study of the Cagliari salterns
… from selected ponds with different salinities. Metagenome-assembled genomes (MAGs) of prokaryotic communities were reconstructed from both matrices in two seasons: winter and summer. The total number of MAGs passing quality thresholds was 2786, of which 1537 from SCV and 1249 from SM. Out of the …

Large-scale metagenomic analysis of food-associated microbial communities and their links with the human microbiome
… collected 583 publicly available food (shotgun) metagenomes and integrated them with 1950 newly sequenced food metagenomes. Through an assembly-based pipeline, I reconstructed >10,000 metagenome-assembled genomes (MAGs) that resulted in 290 previously undescribed taxa and, hence, firstly observed …

Investigating a novel Asgard archaeon and its tubulin-like proteins
… of the origin of the eukaryotic cell. Metagenome-assembled-genomes (MAGs) from various marine environments have shown that this kingdom, officially called Promethearchaeati, encodes many Eukaryotic Signature Proteins (ESPs); proteins that were once thought to be unique but ubiquitous to …
