Bacteria from phyla lacking cultivated representatives are widespread in natural systems and some have very small genomes. Here we test the hypothesis that these cells thus might be enriched by filtration for coupled genomic ultrastructural characterization. Metagenomic analysis of groundwater passed through a ~0.2-μm filter reveals wide diversity bacteria WWE3, OP11 OD1 candidate phyla. Cryogenic transmission electron microscopy demonstrates that, despite morphological variation,...

The human skin microbiome acts as an important barrier protecting our body from pathogens and other environmental influences. Recent investigations have provided evidence that Archaea are a constant but highly variable component of the microbiome, yet factors determine their abundance changes unknown. Here, we tested hypothesis archaea on is influenced by age physiology quantitative PCR 51 different samples taken subjects various age. Our results reveal more abundant in either older than 60...

Polyfurfuryl alcohol (PFA) is one of the most intriguing polymers because, despite its easy polymerization in acid environment, molecular structure definitely not obvious. Many studies have been performed recent decades, and every time, surprising aspects came out. With present study, we aim to take advantage all findings previous investigations exploit them for interpretation completely cured PFA spectra registered with three powerful techniques characterization solid, insoluble polymers:...

Here we present a new bonding protocol for SU-8 negative tone photoresist that exploits the chemical modifications induced in resin by exposure to 254 nm (UVC) light. Fourier Transform Infrared microspectroscopy (μ-FTIR) was used carry out thorough study on processes and occurring within epoxy 365 In particular, established UVC light promotes opening of rings bypassing post-exposure bake. The possibility promote further activation resin, already patterned with standard UV lithography,...

Abstract Sediment-hosted CO2-rich aquifers deep below the Colorado Plateau (USA) contain a remarkable diversity of uncultivated microorganisms, including Candidate Phyla Radiation (CPR) bacteria that are putative symbionts unable to synthesize membrane lipids. The origin organic carbon in these ecosystems is unknown and source CPR lipids remains elusive. We collected cells from groundwater brought surface by eruptions Crystal Geyser, sequenced community, analyzed whole community lipidome...

The release of nanoplastics (NPs) in the environment is a significant health concern for long-term exposed humans. Although their usage has certainly revolutionized several application fields, at nanometer size, NPs can easily interact cellular level, resulting potential harmful effects. Micro/Nanoplastics (M/NPs) have demonstrated impact on mammalian endocrine components, such as thyroid, adrenal gland, testes, and ovaries, while more investigations prenatal postnatal exposure are urgently...
