Extracellular metabolism sets the table for microbial cross-feeding

RK Fritts, AL McCully, JB McKinlay - Microbiology and Molecular …, 2021 - Am Soc Microbiol
The transfer of nutrients between cells, or cross-feeding, is a ubiquitous feature of microbial
communities with emergent properties that influence our health and orchestrate global …

Trehalose/2-sulfotrehalose biosynthesis and glycine-betaine uptake are widely spread mechanisms for osmoadaptation in the Halobacteriales

NH Youssef, KN Savage-Ashlock, AL McCully… - The ISME …, 2014 - academic.oup.com
We investigated the mechanisms of osmoadaptation in the order Halobacteriales, with special
emphasis on Haladaptatus paucihalophilus, known for its ability to survive in low salinities…

[HTML][HTML] Assessing the global phylum level diversity within the bacterial domain: a review

NH Youssef, MB Couger, AL McCully… - Journal of advanced …, 2015 - Elsevier
Microbial ecology is the study of microbes in the natural environment and their interactions
with each other. Investigating the nature of microorganisms residing within a specific habitat …

Microbial mutualism dynamics governed by dose-dependent toxicity of cross-fed nutrients

B LaSarre, AL McCully, JT Lennon… - The ISME …, 2017 - academic.oup.com
Microbial interactions, including mutualistic nutrient exchange (cross-feeding), underpin the
flow of energy and materials in all ecosystems. Metabolic exchanges are difficult to assess …

[HTML][HTML] Systematic characterization of effect of flow rates and buffer compositions on double emulsion droplet volumes and stability

…, KK Brower, VC Suja, G Kim, N Wang, AL McCully… - Lab on a Chip, 2022 - pubs.rsc.org
Double emulsion droplets (DEs) are water/oil/water droplets that can be sorted via
fluorescence-activated cell sorting (FACS), allowing for new opportunities in high-throughput cellular …

Direct cathodic electron uptake coupled to sulfate reduction by Desulfovibrio ferrophilus IS5 biofilms

AL McCully, AM Spormann - Environmental Microbiology, 2020 - Wiley Online Library
Direct electron uptake is emerging as a key process for electron transfer in anaerobic
microbial communities, both between species and from extracellular sources, such as zero‐valent …

Double emulsions as a high-throughput enrichment and isolation platform for slower-growing microbes

AL McCully, MK Loop Yao, KK Brower… - ISME …, 2023 - academic.oup.com
Our understanding of in situ microbial physiology is primarily based on physiological
characterization of fast-growing and readily-isolatable microbes. Microbial enrichments to obtain …

Growth‐independent cross‐feeding modifies boundaries for coexistence in a bacterial mutualism

AL McCully, B LaSarre… - Environmental …, 2017 - Wiley Online Library
Nutrient cross‐feeding can stabilize microbial mutualisms, including those important for
carbon cycling in nutrient‐limited anaerobic environments. It remains poorly understood how …

Reductive tricarboxylic acid cycle enzymes and reductive amino acid synthesis pathways contribute to electron balance in a Rhodospirillum rubrum Calvin-cycle …

AL McCully, MC Onyeziri, B LaSarre… - …, 2020 - microbiologyresearch.org
Purple non-sulfur bacteria (PNSB) use light for energy and organic substrates for carbon
and electrons when growing photoheterotrophically. This lifestyle generates more reduced …

Recipient-biased competition for an intracellularly generated cross-fed nutrient is required for coexistence of microbial mutualists

AL McCully, B LaSarre, JB McKinlay - MBio, 2017 - Am Soc Microbiol
Many mutualistic microbial relationships are based on nutrient cross-feeding. Traditionally,
cross-feeding is viewed as being unidirectional, from the producer to the recipient. This is …
