Discovery And Engineering Of An Endophytic Pseudomonas Strain From Taxus Chinensis For Efficient Production Of Zeaxanthin Diglucoside, Ozkan Fidan, Jixun Zhan

Biological Engineering Faculty Publications

Background

Endophytic microorganisms are a rich source of bioactive natural products. They are considered as promising biofertilizers and biocontrol agents due to their growth-promoting interactions with the host plants and their bioactive secondary metabolites that can help manage plant pathogens. Identification of new endophytes may lead to the discovery of novel molecules or provide new strains for production of valuable compounds.

Results

In this study, we isolated an endophytic bacterium from the leaves of Taxus chinensis, which was identified as Pseudomonas sp. 102515 based on the 16S rRNA gene sequence and physiological characteristics. Analysis of its secondary metabolites revealed …

Exploring The Capacity Of Bacteria For Natural Product Biosynthesis, Ozkan Fidan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation is focused on exploring the potential of bacteria for the biosynthesis of natural products with the purposes of generating novel natural product derivatives and of improving the titer of pharmaceutically important natural products.

A wide variety of compounds from various sources have been historically used in the treatment and prevention of diseases. Natural products as a major source of new drugs are extensively explored due to their huge structural diversity and promising biological activities such as antimicrobial, anticancer, antifungal, antiviral and antioxidant properties. For instance, penicillin as an early-discovered antimicrobial agent has saved millions of lives, indicating the …
