A Gram-staining-positive, motile, aerobic and rod-shaped bacterium, designated strain MA9 was isolated from wetland soil of ecology park, in Seoul, Republic of Korea. This bacterium was characterized to determine its taxonomic position by using the polyphasic approach. Strain MA9 grew at 10-37 °C and at pH 6.0-9.5 on TSB. Menaquinone MK-7 was the predominant respiratory quinone and iso-C, iso-C and C c alcohol were the major fatty acids. The main polar lipids were phosphatidylethanolamine (PE), phosphatidylserine (PS), diphosphatidylglycerol (DPG) and phosphatidylglycerol (PG). The peptidoglycan type of the cell wall was A4α l-Lys-d-Glu. Based on 16S rRNA gene sequencing, strain MA9 clustered with species of the genus and appeared closely related to DSM 12223 (97.8 % sequence similarity), DSM 21993 (97.6 %), DSM 21046 (97.6 %) and DSM 101595 (96.6 %). The G+C content of the genomic DNA was 37.0 mol%. Digital DNA-DNA hybridization between strain MA9 and type strains of , , and resulted in values below 70 %. Strain MA9 could be differentiated genotypically and phenotypically from the recognized species of the genus . The isolate therefore represents a novel species, for which the name sp. nov. is proposed, with the type strain MA9 (=KACC 22212 = LMG 32188).

Lignin displays a highly challenging renewable. To date, massive amounts of lignin, generated in lignocellulosic processing facilities, are for the most part merely burned due to lacking value-added alternatives. Aromatic lignin monomers of recognized relevance are in particular vanillin, and to a lesser extent vanillate, because they are accessible at high yield from softwood-lignin using industrially operated alkaline oxidative depolymerization.

There is growing interest in the use of bio inoculants based on plant growth-promoting bacteria (PGPB) to promote plant growth under biotic and abiotic stresses. Here, we provided a detailed account of the effectiveness of a number of endophytic PGPB strains, isolated from the roots of the halophyte Salicornia brachiata in promoting durum wheat growth and enhancing its tolerance to salinity and fusarium head blight (FHB) disease.

Cis,cis-muconic acid (MA) is a chemical that is recognized for its industrial value and is synthetically accessible from aromatic compounds. This feature provides the attractive possibility of producing MA from mixtures of aromatics found in depolymerized lignin, the most underutilized lignocellulosic biopolymer. Based on the metabolic pathway, the catechol (1,2-dihydroxybenzene) node is the central element of this type of production process: (i) all upper catabolic pathways of aromatics converge at catechol as the central intermediate, (ii) catechol itself is frequently generated during lignin pre-processing, and (iii) catechol is directly converted to the target product MA by catechol 1,2-dioxygenase.

The aim of this study was to evaluate the functional properties of lactic acid bacteria from various sources and to identify strains for use as probiotics. Ten Lactobacillus strains were selected and their properties such as bile tolerance, acid resistance, cholesterol assimilation activity, and adherence to HT-29 cells were assessed to determine their potential as probiotics.
