Borreliae Part 1: Borrelia Lyme Group and Echidna-Reptile Group

open access: yesBiology, 2021
Borreliae are divided into three groups, namely the Lyme group (LG), the Echidna-Reptile group (REPG) and the Relapsing Fever group (RFG). Currently, only Borrelia of the Lyme and RF groups (not all) cause infection in humans.

Comparative Analysis of Root Microbiomes of Rice Cultivars with High and Low Methane Emissions Reveals Differences in Abundance of Methanogenic Archaea and Putative Upstream Fermenters. [PDF]

open access: yes, 2020
Rice cultivation worldwide accounts for ∼7 to 17% of global methane emissions. Methane cycling in rice paddies is a microbial process not only involving methane producers (methanogens) and methane metabolizers (methanotrophs) but also other microbial ...

Exploring the Substrate Switch Motif of Aromatic Ammonia Lyases

open access: yesChemBioChem, Volume 24, Issue 23, December 1, 2023., 2023
Using a bioinformatic approach, we identified novel substrate switch motifs of aromatic ammonia lyases. These alternative amino acids were introduced into a tyrosine ammonia lyase (TALrpc). The characterization of these enzyme variants revealed a significant (up to 20‐fold) improvement in the activity for phenylalanine.

Spatiotemporal dynamics of Spirochaeta, the putative etiologic agent of Akoya oyster disease in pearl oysters, as determined by quantitative PCR

open access: yesAquaculture, 2019
Since the 1990s, Akoya oyster disease (AOD) associated with reddish browning of the soft tissues and mortality of cultured pearl oyster, Pinctada fucata (Gould), has been occurring in the western part of Japan. Although transmission experiments suggested
