A Gram-stain-negative, yellow-green bacterium, designated 1.1416, was isolated from wormcast of . The strain was non-motile, rod-shaped, and grew optimally on NA medium at 30 °C, pH 7.0 and with 0 % (w/v) NaCl. On the basis of the 16S rRNA gene sequence and phylogenetic analysis, 1.1416 showed the highest degree of 16S rRNA gene sequence similarity to 26-35 (96.2 %), followed by G3 (96.1 %). The respiratory quinone of 1.1416 was ubiquinone-8 (Q-8), and its major cellular fatty acids were iso-C (39.8 %), summed feature 9 (iso-C ω9 or C 10-methyl) (18.6 %). The major polar lipids of 1.1416 were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine and six unidentified phospholipids. The genomic DNA G+C content of 1.1416 was 71.0 mol%. According to the results of the phenotypic and chemotaxonomic phylogenetic analyses, strain 1.1416 represents a novel species of the genus , for which the name sp. nov. is proposed, with strain 1.1416 (=KCTC 62979=CCTCC AB 2018348) as the type strain.

Biological control agents (BCAs) are considered as one of the most important strategies for controlling wilt, and bioorganic fertilizer, in particular, has been extensively investigated. However, little is known regarding how a biocontrol microorganism affects the suppression mechanisms when combined with different amendments. In this study, a pot experiment was performed using banana plants to investigate the different mechanisms by which the biocontrol bacterium HN03 (isolated from our laboratory) and amendments suppress wilt.

Performance and mechanisms of a microbial-earthworm ecofilter for removing organic matter and nitrogen from synthetic domestic wastewater.

The performance of a microbial-earthworm ecofilter for the treatment of synthetic domestic wastewater is evaluated, and the mechanisms of organic matter and nitrogen transformation investigated. Vermifiltration efficiently reduced chemical oxygen demand (COD) and ammonia nitrogen (NH(3)-N) from the influent. A combination of soil with sawdust possessed higher porosity and specific surface area than other media, and this microporous structure together with wormcast surface greatly facilitated COD reduction at depths from 5 to 35 cm.
