Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, Volume 293, Issue 10, Page 2908-2927, May 2026.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Bacteriological water quality of Six Mile Lake

open access: yes, 1971
During the 1970 surveys, Six Mile Lake had bacterial levels less than the water quality criteria for total body contact recreation. The only exception to this situation was the higher fecal streptococcus levels at two stations, 11 and 40. The geometric mean bacterial levels can be summarized as follows: Survey: August 29 - September 1, 1970 Total ...

First Description and Characterisation of Lactococcus garvieae Strains Causing Septicaemic Disease in Farmed Sea Bass (Dicentrarchus labrax; Linnaeus) in Spain

open access: yesJournal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT This study presents the first description and characterisation of Lactococcus garvieae isolated from diseased European sea bass (Dicentrarchus labrax) farmed in Spain. During autumn 2023, two fish farms were affected by infectious outbreaks causing moderate cumulative fish mortality (5%–10%). Diseased fish showed clinical signs of haemorrhagic

Acidic pH Restricts Non‐Tuberculous Mycobacteria Replication

open access: yesMolecular Microbiology, Volume 125, Issue 5, Page 375-388, May 2026.
Different nontuberculous mycobacteria (NTM) species display unique replication profiles in acidic pH in vitro which correlates to their replication within human macrophages. Inhibition of the acidic environments within the macrophage enhances bacterial viability emphasising the role of acidic pH during NTM infections.

The Ti Plasmid‐Encoded VirJ Functions as a Lysyl‐Phosphatidylglycerol Hydrolase in Agrobacterium tumefaciens

open access: yesMolecular Microbiology, Volume 125, Issue 5, Page 426-441, May 2026.
We identify the long‐known virulence factor VirJ as a lysyl‐phosphatidylglycerol (L‐PG) hydrolase. Like the chromosomally encoded virulence factor AcvB, it prevents excessive accumulation of L‐PG in the membrane, thereby maintaining efficient T‐DNA transfer via the Type IV secretion system (T4SS) in Agrobacterium tumefaciens.

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1

open access: yesMolecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.
A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...
