Delayed Ripening of Climacteric Fruit by Catalysts Prepared from Induced Cells ofRhodococcus rhodochrousDAP 96253: A Case for the Biological Modulation of Yang-Cycle Driven Processes by a Prokaryote

Abstract

Induced cells of Rhodococcus rhodochrous DAP 96253, when placed in the proximity of climacteric fruit (peaches, bananas, avocados) delay the ripening of the fruit. Examination of the delayed ripening shows that the induced cells possess multiple mechanisms that have the potential to impact the Yang Cycle in climacteric plants and processes such as volatile flavor and fragrance compounds related to the climacteric process. The suggestion is brought forward that these induced R. rhodochrous cells possess the ability to modify/modulate an important plant process.

Exploring the Role of Microbial Live Factories in Post-Harvest Management of Potatoes-Possible Solution to the Optimization of Supply Chain

“…Many bacteria in soil and plants possess ACC deaminase activity, which cleaves ACC to 2-oxobutyrate and ammonia and can contribute to ethylene balancing in plants [111,118]. An alternative role of ethylene in microbialdriven modulation of ripening was introduced by a recent study exploring the potential of a Rhodococcus rhodochrous strain to delay ripening in different species of climacteric fruits [121]. In this case, the proposed mechanism is ethylene-induced nitrile hydratase and/or nitrilase activity in the bacterium, which resulted in maintenance of fruit firmness and reduced spotting and spoilage [121].…”
