Abstract
Two novel strains were isolated from wetland soils in Goyang, Republic of Korea. The two Gram-stain-positive, facultatively anaerobic, rod-shaped bacterial-type strains were designated MW4T and MW9T. Phylogenomic analysis based on whole-genome sequences suggested that both strains belonged to the genus Cellulomonas. The cells of strain MW4T were non-motile and grew at 20-40 °C (optimum, 35 °C), at pH 6.0-10.0 (optimum, pH 8.0) and in the presence of 0-1.0% NaCl (optimum, 0 %). The cells of strain MW9T were non-motile and grew at 20-40 °C (optimum, 35 °C), at pH 5.0-9.0 (optimum, pH 8.0) and in the presence of 0-1.0% NaCl (optimum, 0 %). The average nucleotide identity (77.1-88.1 %) and digital DNA-DNA hybridization values (21.0-34.8 %) between the two novel strains and with their closely related strains fell within the range for the genus Cellulomonas. The novel strains MW4T and MW9T and reference strains possessed alkane synthesis gene clusters (oleA, oleB, oleC and oleD). Phylogenomic, phylogenetic, average nucleotide identity, digital DNA-DNA hybridization, physiological and biochemical data indicated that the novel strains were distinct from other members of the family Cellulomonadaceae. We propose the names Cellulomonas alba sp. nov. (type strain MW4T=KACC 23260T=TBRC 17645T) and Cellulomons edaphi sp. nov. (type strain MW9T=KACC 23261T=TBRC 17646T) for the two strains.

Abstract
The microbial degradation of lignocellulose is the best way to treat straw, which has a broad application prospect. It is consistent with the idea of agricultural sustainable development and has an important impact on the utilization of biomass resources. To explore and utilize the microbial resources of lignocellulose degradation, 27 lignocellulose degrading strains were screened from 13 regions in China. ZJW-6 was selected because of its 49.6% lignocellulose weight loss rate. According to the theoretical analysis of the experimental results, the following straw degradation conditions were obtained by ZJW-6: nitrogen source input of 8.45 g/L, a pH of 8.57, and a temperature of 31.63°C, the maximum weight loss rate of rice straw could reach 54.8%. It was concluded that ZJW-6 belonged to Cellulomonas iranensis according to 16S rRNA-encoding gene sequence comparison and identification. ZJW-6 is a Gram-positive bacterium that grows slowly and has a small yellowish green colony. To explain the degradation mechanism of lignocellulose, the experiment of enzymatic properties of the strain was prepared and carried out. It was discovered that ZJW-6 has an excellent ability to degrade cellulose, hemicellulose, and lignin, with cellulose and hemicellulose loss rates reaching almost 50% in 4 days and lignin loss rates reaching nearly 30%. Furthermore, ZJW-6 demonstrated lignocellulose degradation under aerobic and anaerobic conditions, indicating the strain's broad application potential. ZJW-6 was found to be more effective than ordinary humic acid in improving rice soil (available phosphorus, available nitrogen, organic matter) and promoting rice growth in a rice pot experiment (increasing root-shoot ratio, root activity, chlorophyll content and net photosynthetic rate). ZJW-6 plays an important role in promoting the development and utilization of straw resources. It has important significance for the advancement of green agriculture.

Abstract
Six Gram-stain-positive, aerobic or facultative anaerobic, catalase-positive, urease- and oxidase-negative, rod-shaped bacteria (zg-ZUI157T/zg-ZUI40, zg-ZUI222T/zg-ZUI199 and zg-ZUI188T/ zg-ZUI168) were characterized by a polyphasic approach. Optimal growth of the six strains was observed at pH 7.0 and 28 °C. Phylogenetic analyses based on the 16S rRNA gene and 247 core genes revealed that they belong to genus
Cellulomonas
. The three type strains have low digital DNA-DNA hybridization (19.3–30.1%) and average nucleotide identity values (78.0-85.5%) with all available genomes in the genus
Cellulomonas
, and a DNA G+C content range of 73.0-74.6 mol%. The major fatty acids detected in strain pairs zg-ZUI157T/zg-ZUI40 and zg-ZUI 222T/zg-ZUI199 were C16:0, anteiso-C15:0 and anteiso A-C15:1, and C16:0, anteiso-C15:0, anteiso A-C15:1 and anteiso-C17:0 in strain pair zg-ZUI188T/zg-ZUI168. Diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol mannosides were the major polar lipids detected in the three novel species. MK-9(H4) was the predominant quinone detected in strains zg-ZUI222T (87.4 %) and zg-ZUI188T (91.4 %), and MK-9(H4) (49.1 %) and MK-8 (43.4 %) in strain zg-ZUI157T. The cell-wall sugars detected in the three novel species mainly contained rhamnose. The cell-wall peptidoglycan type of the three novel species was A4β, with an inferred l-Orn–d-Asp interpeptide bridge for strains zg-ZUI157T and zg-ZUI222T, and l-Orn–d-Glu for strain zg-ZUI188T. Based on the results of the phenotypic, phylogenetic, genomic hybridization, average nucleotide identity and chemotaxonomic analyses, the six strains should be classified as belonging to three novel
Cellulomonas
species, for which the names Cellulomonas dongxiuzhuiae sp. nov. (zg-ZUI157T=GDMCC 1.2559T=KCTC 49678T), Cellulomonas wangleii sp. nov. (zg-ZUI222T=GDMCC 1.2501T=KCTC 49675T) and Cellulomonas fengjieae sp. nov. (zg-ZUI188T=GDMCC 1.2563T=KCTC 49674T) are proposed.

Abstract
Metagenomics in agricultural research allows for searching for bioindicators of soil health to characterize changes caused by management practices. Cover cropping (CC) improves soil health by mitigating nutrient losses, yet the benefits depend on the tillage system used. Field studies searching for indicator taxa within these systems are scarce and narrow in their scope. Our goal was to identify bioindicators of soil health from microbes that were responsive to CC (three levels) and tillage (chisel tillage, no-till) treatments after five years under field conditions. We used rRNA gene-based analysis via Illumina HiSeq2500 technology with QIIME 2.0 processing to characterize the microbial communities. Our results indicated that CC and tillage differentially changed the relative abundances (RAs) of the copiotrophic and oligotrophic guilds. Corn-soybean rotations with legume-grass CC increased the RA of copiotrophic decomposers more than rotations with grass CC, whereas rotations with only bare fallows favored stress-tolerant oligotrophs, including nitrifiers and denitrifiers. Unlike bacteria, fewer indicator fungi and archaea were detected; fungi were poorly identified, and their responses were inconsistent, while the archaea RA increased under bare fallow treatments. This is primary information that allows for understanding the potential for managing the soil community compositions using cover crops to reduce nutrient losses to the environment.

Abstract
Two Gram-stain-positive, facultatively anaerobic, motile, aerobic, rod-shaped and non-spore-forming actinobacteria, strains AO-9T and AO-18, were isolated from paddy soil collected from Daejeon, Republic of Korea. Colonies were smooth, lemon-yellow and circular and 0.5-0.8×2.0-2.4 µm in diameter after 3 days of incubation at 28 °C on tryptic soy agar. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains AO-9T and AO-18 belonged to the genus Cellulomonas, showing the highest sequence similarities to Cellulomonas marina FXJ8.089T (96.6 %), Cellulomonas endophytica SYSUP0004T (96.5 %), Cellulomonas gelida DSM 20111T (96.2 %), Cellulomonas uda DSM 20107T (96.1 %), Cellulomonas rhizosphaerae NEAU-TCZ24T (96.1 %), Cellulomonas composti TR7-06T (96.0 %), Cellulomonas persica JCM 18111T (96.0 %) and less than 96 % to other closely related species. The DNA-DNA hybridization values between strains AO-9T and AO-18 were 87 %. The average nucleotide identity and digital DNA-DNA hybridization values between strain AO-9T and type strains of related species of the genus Cellulomonas were 84.0-85.8 % and 20.3-20.9 %, respectively. The major cellular fatty acids are anteiso-C15:0 (49.9 %), C14:0 (12.9 %) and iso-C14:0 (12.1 %). The predominant isoprenoid quinone was MK-9 (H4). The polar lipid profile consists of diphosphatidylglycerol, phosphatidylglycerol and one unidentified lipid. The DNA G+C content was 72.9 mol%. Based on its distinctive phenotypic, phylogenetic and chemotaxonomic characteristics, the two strains are considered to represent novel species of the genus Cellulomonas, for which the name Cellulomonas citrea sp. nov. is proposed. The type strain is AO-9T (=KACC 19069T=NBRC 112523T).

Abstract
Two Gram-stain-positive, catalase-positive and oxidase-negative, aerobic, non-motile, cellobiose-utilizing, short-rod-shaped strains (Z28T and Z29) were isolated from faeces of Tibetan antelope (Pantholops hodgsonii) collected on the Qinghai-Tibet Plateau. Strain Z28T shared 98.1, 98.0, 97.8 and 97.4 % 16S rRNA gene similarity, 24.1, 22.8, 23.2 and 26.3 % digital DNA-DNA hybridization relatedness and 80.8, 80.0, 80.7 and 80.9 % average nucleotide identity values with Cellulomonas oligotrophica DSM 24482T, Cellulomonas flavigena DSM 20109T, Cellulomonas iranensis DSM 14785T and Cellulomonas terrae JCM 14899T, respectively. Results from further phylogenetic analyses based on the 16S rRNA gene and 148 core genes indicated that strains Z28T and Z29 were closest to C. oligotrophica DSM 24482T and C. flavigena DSM 20109T, but clearly separated from the currently recognized species of the genus Cellulomonas. The genomic DNA G+C content of strain Z28T was 75.3 mol%. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C15 : 1 A, C16 : 0 and anteiso-C17 : 0. Ribose and mannose were detected as the whole-cell sugars. The major respiratory quinone was MK-9(H4) and ornithine was the diamino acid of the cell wall. The polar lipids present in strain Z28T were phosphatidylethanolamine, five phospholipids, two aminophospholipids, aminolipid and three unidentified lipids. Comparison of phenotypic and phylogenetic features between the two strains and the related organisms revealed that Z28T and Z29 represent a novel species of the genus Cellulomonas, for which the name Cellulomonas shaoxiangyii sp. nov. is proposed. The type strain is Z28T (=CGMCC 1.16477T=DSM 106200T).
