A pink-pigmented, Gram-negative, rod-shaped, motile, strictly aerobic bacterium, designated strain 311(T), was isolated from desert sand in Xinjiang, China. Phylogenetic analyses based on 16S rRNA gene sequences showed that 311(T) related closely to Cesiribacter andamanensis AMV16(T) (94.6% similarity). The DNA G+C content of 47.1 mol% and the major respiratory quinone menaquinone 7 (MK-7). main cellular fatty acids were C(16:1)ω5c (29.9%), iso-C(15:0) (21.9%), iso-C(17:0) 3-OH (13.3%)...

A Gram-stain-negative, short rod-shaped, motile (by gliding) bacterial strain, designated A12 T , was isolated from tundra soil collected Ny-Ålesund, in the Arctic region of Norway. The temperature, NaCl and pH ranges for growth were 4–25 °C (optimum, 18 °C), 0–2 % 0 %) 6–9 7). Phylogenetic analysis based on 16S rRNA gene sequences revealed that isolate belonged to genus Pedobacter showed highest sequence similarity (94.4 daechungensis KCTC 12637 . DNA G+C content (38.3 mol%), polar lipid...

Abstract Dendrobium huoshanense is used to treat various diseases in traditional Chinese medicine. Recent studies have identified active components. However, the lack of genomic data limits research on biosynthesis and application these therapeutic ingredients. To address this issue, we generated first chromosome-level genome assembly annotation D. huoshanense. We integrated PacBio sequencing data, Illumina paired-end Hi-C assemble a 1.285 Gb genome, with contig scaffold N50 lengths 598 kb...

Introduction Furfural, a main inhibitor produced during pretreatment of lignocellulose, has shown inhibitory effects on S. cerevisiae . Method In the present study, new strains named 12–1 with enhanced resistance to furfural were obtained through adaptive laboratory evolution, which exhibited shortened lag phase by 36 h, and an increased ethanol conversion rate 6.67% under 4 g/L furfural. Results Discussion To further explore mechanism tolerance, ADR1_1802 mutant was constructed CRISPR/Cas9...

Background: With global warming and climate change, the occurrence of abiotic stresses has become increasingly prevalent. Drought often occurs with high temperatures, especially in arid semi-arid regions. However, molecular mechanisms plants responding to combined drought high-temperature stress remains unclear. Results: Through integrative physiological, transcriptomic, metabolomic analyses, we systematically investigated adaptive Dendrobium huoshanense under stress. Our findings revealed...

Tyrosol is an important drug precursor, and Saccharomyces cerevisiae one of the main microorganisms that produces tyrosol. Although excessive metabolic modification increases production tyrosol, it also causes a decrease in growth rate yeast. Therefore, this study attempted to restore S. through adaptive evolution further improve tyrosol production. After laboratory S26, three evolutionary strains were obtained. The biomass strain S26-AE2 reached 17.82 g DCW/L presence 100 g/L glucose, which...

Two Gram-negative, rod-shaped, gliding and pink-pigmented bacterial strains, X14-1T X19-1, were isolated from a mixture of sand samples collected the desert Xinjiang, China, characterized by using polyphasic taxonomic approach. Strains X19-1 contained MK-7 as predominant menaquinone. The major cellular fatty acids included iso-C15 : 0, iso-C17 0 3-OH, summed feature 3 4. DNA G+C contents strains 48.2 48.9 mol%, respectively. 16S rRNA gene sequence analysis showed that isolates highly related...

A Gram-negative, rod-shaped, non-motile, strictly aerobic bacterium, strain S3-63(T), was isolated from desert sand of Xinjiang, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that S3-63(T) had highest similarity to type strains the genus Altererythrobacter, i.e. Altererythrobacter marinus H32(T) (97.2% similarity), marensis MSW-14(T) (95.9%), aestuarii KCTC 22735(T) (95.5%), epoxidivorans JCS350(T) (95.1%), namhicola 22736(T) luteolus SW-109(T) (95.0%) and indicus LMG...
