Microbiological Comparisons within and across Contiguous Lacustrine, Paleosol, and Fluvial Subsurface Sediments [PDF]

open access: yesApplied and Environmental Microbiology, 1995
Twenty-six subsurface samples were collected from a borehole at depths of 173.3 to 196.8 m in the saturated zone at the Hanford Site in south-central Washington State. The sampling was performed throughout strata that included fine-grained lacustrine (lake) sediments, a paleosol (buried soil) sequence, and coarse-grained fluvial (river) sediments.

Hierarchically Rough rGO/HAp Nanocoatings on SLM Ti–6Al–4 V Implants for Enhanced Biointegration

open access: yesSmall, EarlyView.
This study investigates HAp/rGO bioactive coatings on Ti‐6Al‐4V fixation implants fabricated by selective laser melting with systematically varied volumetric energy density to tailor the as‐built surface state. Composite coatings were deposited by electrophoretic deposition and characterized using micro‐CT, profilometry, FESEM/EDS, and detailed XPS to ...

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

open access: yesIntegrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the

Graphene oxide–modified fluoridated varnish promotes mineral recovery in demineralized bovine enamel: An in vitro study

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the efficacy of an experimental fluoridated varnish modified with graphene oxide (GO) nanoparticles in arresting initial caries lesion progression and promoting mineral recovery in demineralized bovine enamel.

Water distribution in laterals and units of subsurface drip irrigation. II: Field evaluation. [PDF]

open access: yes, 2009
The performance of drip irrigation and subsurface drip irrigation (SDI) laterals has been compared. Two emitter models (one compensating and the other noncompensating) were assessed.

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

open access: yesJournal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Microbiological Quality of Subsurface Drainage Water from Irrigated Agricultural Land [PDF]

open access: yesJournal of Environmental Quality, 1972
AbstractIrrigation and subsurface drainage waters sampled from an 82,150‐hectare (203,000‐acre) irrigation district in southern Idaho were evaluated for bacteriological quality. The soils in the district are wind deposited over fractured basalt, calcareous, and have a pH near 7.8.

Beyond Bactericidal: Plasma Surface Engineering to Defeat Food Matrix‐Conditioning Layers

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The persistence of foodborne pathogens on industrial food contact surfaces continues to challenge global food safety despite advances in sanitation technologies. A central limitation of current antimicrobial strategies lies in their validation under simplified laboratory conditions that overlook the physicochemically driven formation of food ...

Identification and Removal of Contaminant Sequences From Ribosomal Gene Databases: Lessons From the Census of Deep Life

open access: yesFrontiers in Microbiology, 2018
Earth’s subsurface environment is one of the largest, yet least studied, biomes on Earth, and many questions remain regarding what microorganisms are indigenous to the subsurface. Through the activity of the Census of Deep Life (CoDL) and the Deep Carbon
