Predicting oil contamination in water using machine learning on microbial compositions.

Tong Gao; Isaac Bigcraft; Stephen Techtmann et al.

PLoS ONE, Vol. 21 No. 3 · 2026 · English · DOAJ Scopus

We present a compact and generative machine-learning framework that predicts oil contamination based on microbial community compositions from experimental samples. Our method combines dimensionality reduction with data augmentation and generative modeling to address high-dimensional, non-linear…

Open Source Vacuum Oven Design for Low-Temperature Drying: Performance Evaluation for Recycled PET and Biomass

Benjamin R. Hubbard; Lindsay I. Putman; Stephen Techtmann et al.

Journal of Manufacturing and Materials Processing, Vol. 5 No. 2 · 2021 · English · DOAJ Scopus

Vacuum drying can dehydrate materials further than dry heat methods, while protecting sensitive materials from thermal degradation. Many industries have shifted to vacuum drying as cost- or time-saving measures. Small-scale vacuum drying, however, has been limited by the high costs of specialty…

Coexistence of specialist and generalist species within mixed plastic derivative-utilizing microbial communities

Laura Schaerer; Lindsay Putman; Isaac Bigcraft et al.

Microbiome, Vol. 11 No. 1 · 2023 · English · DOAJ Scopus

Abstract Background Plastic-degrading microbial isolates offer great potential to degrade, transform, and upcycle plastic waste. Tandem chemical and biological processing of plastic wastes has been shown to substantially increase the rates of plastic degradation; however, the focus of this work has…

Microbial Communities across Global Marine Basins Show Important Compositional Similarities by Depth

John I. Miller; Stephen Techtmann; Dominique Joyner et al.

mBio, Vol. 11 No. 4 · 2020 · English · DOAJ Scopus

ABSTRACT The environmental surveys following the 2010 Deepwater Horizon (DWH) spill identified a variety of hydrocarbon-degrading microorganisms, and laboratory studies with field-collected water samples then demonstrated faster-than-expected hydrocarbon biodegradation rates at 5°C. Knowledge about…

Oil Hydrocarbon Degradation by Caspian Sea Microbial Communities

John I. Miller; Stephen Techtmann; Julian Fortney et al.

Frontiers in Microbiology, Vol. 10 · 2019 · English · DOAJ Scopus

The Caspian Sea, which is the largest landlocked body of water on the planet, receives substantial annual hydrocarbon input from anthropogenic sources (e.g., industry, agriculture, oil exploration, and extraction) and natural sources (e.g., mud volcanoes and oil seeps). The Caspian Sea also…
