Comparison of Three Xylose Pathways in Pseudomonas putida KT2440 for the Synthesis of Valuable Products

Frontiers in Bioengineering and Biotechnology, 2020
Pseudomonas putida KT2440 is a well-established chassis in industrial biotechnology. To increase the substrate spectrum, we implemented three alternative xylose utilization pathways, namely the Isomerase, Weimberg, and Dahms pathways.

The Weimberg pathway: an alternative for Myceliophthora thermophila to utilize d-xylose

Biotechnology for Biofuels and Bioproducts, 2023
Background With d-xylose being the second most abundant sugar in nature, its conversion into products could significantly improve biomass-based process economy. There are two well-studied phosphorylative pathways for d-xylose metabolism. One is isomerase

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...

Mining Xylose Isomerase Producing Microbes [PDF]

Madras Agricultural Journal, 2020
An aerobic, rod shaped, mesophilic, gram positive xylitol producing bacterial isolates were made from different enriched substrates. Xylose isomerase is an enzyme that catalyzes the interconversion of D-xylose and D-xylulose. The microbes producing xylulose from xylose via xylose isomerase enzyme were screened for the xylose isomerase activity based on

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2541-2558, April 2026.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Convergent Evolution and De Novo Reconstitution of Apiin Biosynthesis

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2562-2575, April 2026.
ABSTRACT Apiin, an active flavonoid apioside, occurs in phylogenetically distant plants, such as parsley and chilli pepper (Capsicum annuum L.). Its sporadic distribution suggests the existence of convergent apiin biosynthesis; however, the molecular mechanisms underlying this convergence remain unclear.
