Avis Lab Publishes on Methods to Reduce Potato Spoilage

January 27, 2021

Time to read: 1 minutes

Potato is the largest vegetable crop in Canada. However, it is susceptible to numerous spoilage microorganisms including Fusarium species causing dry rot disease. The disease affects up to 60% of potato tubers during storage and causes up to 25% loss. Fusarium species also produce toxic compounds, which may pose a health risk. Chemical treatments (i.e., pesticide application) are typically used to control dry rot. Chemical treatments have drawbacks, including potential negative effects on health and the environment as well as development of antimicrobial resistance.

Serine Ramlawi (MSc graduate Chemistry/Food Science) and two undergraduate students from the Research Laboratory of Prof. Tyler Avis have published a scientific research paper on the potential of beneficial bacteria as alternatives to control spoilage of potatoes. The paper can be read here (). For more information on the Avis Lab’s research, see /avislab/.

Congratulation to graduate students Anna Koudrina, Emma Wistaff & Tristan Smythe for winning three University wide scholarships!


PhD candidate Anna Koudrina from Dr. M. DeRosa lab wins Koningstein Scholarship. In collaboration with Dr. E. Tsai at the Ottawa Hospital/OHRI, Anna uses aptamers in the development of targeted contrast agents for applications in MRI and CT imaging. These novel conjugates allow for early diagnosis and more precise treatment, while lowering toxicity of the conventionally used contrast media. Anna’s primary focus centers around conditions that involve clotting of blood.
	MSc Candidate Emma Wistaff from Jeff Smith’s lab & OHRI lab wins Irene Ethel Cockburn Bursary. Emma is investigating a potential drug candidate for use in viral oncolytic therapies for the treatment of various cancer types. Emma is primarily focused on analyzing the binding location of the drug candidate within cells and the break down of the drug into metabolites over time using proteomics and metabolomics by liquid chromatography-mass spectrometry (LC-MS) and chemometrics.
PhD candidate Tristan Smythe from Robert Letchers Lab wins the CUASA Scholarship. Tristan’s work is focused on the environmental fate of a recently discovered class of highly brominated flame retardant chemicals, and focusing on their uptake, distribution, and metabolism within herring gulls – an avian biomonitoring species for contaminant burdens within the Great Lakes area. This work involves the development of analytical techniques (i.e. GC-ECNI-MS and UPLC-TQS-MS/MS) to detect and quantify them in both biotic and abiotic matrices, as well as the development and use of in vitro bioassays to characterize the structure-specific metabolism-kinetics of various structural-isomers using a herring gull liver microsomal system.

MSc Candidate Grace Daly in Dr. David Miller’s Lab presented on “Can we push out the cheaters?” at the Partnership Exchange this past week.

Plants and fungal endophytes exist in a mutualistic symbiotic relationship, where both organisms benefit from the activity of the other. Some endophytes are ‘cheaters‘ because they use the plant for its resources without providing any benefits in return. The white pine blister rust, is a fungal pathogen which kills white pine trees and therefore heavily impacts Canada’s forestry industry. Certain endophytes produce beneficial chemicals that help the tree defend itself against harmful fungal pathogens and insects. We are trying to identify fungal endophytes of white pine, which produce chemicals that are specifically toxic to the white pine blister rust. The goal is to introduce these ‘good fungi’ into pine seedlings, to ultimately push out the cheating endophytes and help the tree be more tolerant to the pathogen.
