Pyrroloquinoline Quinone Improves Ram Sperm Quality through Its Antioxidative Ability during Storage at 4 °C

Antioxidants
Sperm motility is an important factor in the migration of sperm from the uterus to the oviduct. During sperm preservation in vitro, sperm generates excessive ROS that damages its function.

Exploring Ectoine Production From Methanol, Formate, and Electrochemically Produced Formate by Methyloligella halotolerans

Engineering in Life Sciences, Volume 26, Issue 1, January 2026.
ABSTRACT Microbial synthesis using renewable C1‐carbon sources like electrochemically produced formate (e‐formate) represents a promising approach for climate‐neutral chemical production. This study investigates formate utilization for ectoine biosynthesis by the halophilic methylotroph Methyloligella halotolerans.

L-tyrosine is the precursor of PQQ biosynthesis in Hyphomicrobium X

, 1988
A method was developed to study amino acids as possible precursors of PQQ biosynthesis. Cultures of Hyphomicrobium X, growing on [13C]methanol, were supplemented with unlabelled amino acids.

Investigation of the structure and mechanism of a PQQ biosynthetic pathway component, PqqC, and a bioinformatics analysis of potential PQQ producing organisms. [PDF]

, 2010
PQQ is an exogenous, tricyclic, quino-cofactor for a number of bacterial dehydrogenase reaction. It has also been proposed to play a role as a bacterial vitamin. The following work has defined 144 bacteria species that contain the machinery to form PQQ.

Glucose oxidation and PQQ-dependent dehydrogenases in Gluconobacter oxydans

, 2009
Gluconobacter oxydans is famous for its rapid and incomplete oxidation of a wide range of sugars and sugar alcohols. The organism is known for its efficient oxidation of D-glucose to D-gluconate, which can be further oxidized to two different keto-D ...
