Microcystis, a common harmful algal bloom (HAB) taxon, threatens water supplies and human health, yet species delimitation is contentious in this leading to challenges research management of threat. Historical morphology-based classifications recognize multiple morphospecies, most with variable diverse ecologies, while DNA sequence-based indicate single ecotypes. To better delimit Microcystis species, we conducted pangenome analysis 122 genomes. Core- non-core gene phylogenetic analyses...
Bacterial community composition of different sized aggregates within the Microcystis cyanobacterial phycosphere were determined during summer and fall in Lake Taihu, a eutrophic lake eastern China. Bloom samples taken August September represent healthy bloom biomass, whereas from October decomposing biomass. To improve our understanding complex interior structure phycosphere, separated into large (>100 µm), medium (10–100 µm) small (0.2–10 size aggregates. Species richness library coverage...
This study investigated the interaction of macrophyte Acorus calamus and sediment microbial fuel cells (SMFC) during degradation high molecular weight-polycyclic aromatic hydrocarbons (HMW-PAHs) in sediments. Over 367-days, combination SMFC led to an increase pyrene benzo[a]pyrene rates by at least 70% compared or alone. While either increased redox potential sediments, potentials near anode (approximately 6 cm depth) macrophyte-SMFC were markedly lower than that only treatment. Moreover,...
Abstract Bacteria play key roles in the function and diversity of aquatic systems, but aside from study specific bloom little is known about or biogeography bacteria associated with harmful cyanobacterial blooms (cyanoHABs). CyanoHAB species are to shape bacterial community composition rely on functions provided by bacteria, leading hypothesized cyanoHAB interactome, a coevolved synergistic interacting species, each necessary for success others. Here, we surveyed microbiome Microcystis...
Sediment microbial fuel cells (SMFCs) can stimulate the degradation of polycyclic aromatic hydrocarbons in sediments, but mechanism this process is poorly understood at functional gene level. Here, use SMFC resulted 92% benzo[a]pyrene (BaP) removal over 970 days relative to 54% controls. functions, community structure, and network interactions were dramatically altered by employment. Functional analysis showed that c-type cytochrome genes for electron transfer, genes, extracellular...
Abstract Background During the bloom season, colonial cyanobacterium Microcystis forms complex aggregates which include a diverse microbiome within an exopolymer matrix. Early research postulated simple mutualism existing with bacteria benefitting from rich source of fixed carbon and receiving recycled nutrients. Researchers have since hypothesized that represent community synergistic interacting species, interactome, each unique metabolic capabilities are critical to growth, maintenance,...
In the Chesapeake Bay, picocyanobacteria were usually 100-fold less abundant in winter than summer. However, little is known about how picocyanobacterial populations shift between and summer bay. This due mainly to undetectable bacterial 16S rRNA clone libraries. this study, bay detected using picocyanobacterium-specific primers compared based on analysis of internal transcribed spacer sequences. Temperature was found be dominant environmental factor controlling Bay. summer, marine cluster B...
Phytoplasmas were detected in cactus (Opuntia species) plants exhibiting witches'-broom disease symptoms Yunnan Province, south-western China. Comparative and phylogenetic analyses of 16S rRNA gene sequences indicated that an overwhelming majority the cactus-infecting phytoplasmas under study belonged to peanut phytoplasma group (16SrII). Genotyping through use computer-simulated restriction fragment length polymorphism (RFLP) analysis genes revealed a remarkable genetic diversity among...
Many podoviruses have been isolated which infect marine picocyanobacteria, and they may play a potentially important role in regulating the biomass population composition of picocyanobacteria. However, little is known about diversity dynamics autochthonous cyanopodoviruses environments. Using set newly designed PCR primers specifically amplify DNA pol from cyanopodoviruses, total 221 sequences were retrieved eight Chesapeake Bay virioplankton communities collected at different times...
A bacterial strain, designated NLS-7 T , was isolated through enrichment of landfill cover soil in methane-oxidizing conditions. Strain is a Gram-stain negative, non-motile rod, approximately 0.8 µm wide by 1.3 long. Phylogenetic analysis based on 16S rRNA gene sequencing places it within the genus Methylocystis with its closest relatives being M. hirsuta silviterrae and rosea 99.9, 99.7 99.6 % sequence similarity respectively. However, average nucleotide identity amino acid values below 95...
