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 …

[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 …

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…

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 …
