Engineered N57P Variant of Ulvan Lyase with Improvement of Catalytic Efficiency and Thermostability via Reducing Loop Flexibility and Anchoring Substrate

open access: yes, 2021
Ulvan lyase degrades the ulvan from green macroalgae, which is a very attractive biocatalyst in algae biomass degradation. Here, a novel N57P mutant from Nonlabens ulvanivorans ulvan lyase (NuPL28) with improved catalytic efficiency and thermostability ...

Characterization of an Alteromonas long-type ulvan lyase involved in the degradation of ulvan extracted from Ulva ohnoi

open access: yes, 2017
Ulvan is a sulfated polysaccharide found in the cell wall of the green algae Ulva. We first isolated several ulvan-utilizing Alteromonas sp. from the feces of small marine animals. The strain with the highest ulvan-degrading activity, KUL17, was analyzed

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

The significance of microbiota in New Zealand seaweed aquaculture

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 3, Page 509-536, September 2025.
ABSTRACT Seaweed‐associated microbes are the metabolic heavy lifters in the symbiotic relationship between the seaweed microbiome and their host macroalgae. In exchange for fixed carbon and an exclusive niche habitat offered by the host, the microbial consort performs a litany of crucial metabolic functions including vitamin production, nitrogen ...
