Kaistella Soli Sp. Nov., Isolated from Oil-Contaminated Soil
A001 Kaistella soli sp. nov., Isolated from Oil-contaminated Soil Dhiraj Kumar Chaudhary1, Ram Hari Dahal2, Dong-Uk Kim3, and Yongseok Hong1* 1Department of Environmental Engineering, Korea University Sejong Campus, 2Department of Microbiology, School of Medicine, Kyungpook National University, 3Department of Biological Science, College of Science and Engineering, Sangji University A light yellow-colored, rod-shaped bacterial strain DKR-2T was isolated from oil-contaminated experimental soil. The strain was Gram-stain-negative, catalase and oxidase positive, and grew at temperature 10–35°C, at pH 6.0– 9.0, and at 0–1.5% (w/v) NaCl concentration. The phylogenetic analysis and 16S rRNA gene sequence analysis suggested that the strain DKR-2T was affiliated to the genus Kaistella, with the closest species being Kaistella haifensis H38T (97.6% sequence similarity). The chemotaxonomic profiles revealed the presence of phosphatidylethanolamine as the principal polar lipids;iso-C15:0, antiso-C15:0, and summed feature 9 (iso-C17:1 9c and/or C16:0 10-methyl) as the main fatty acids; and menaquinone-6 as a major menaquinone. The DNA G + C content was 39.5%. In addition, the average nucleotide identity (ANIu) and in silico DNA–DNA hybridization (dDDH) relatedness values between strain DKR-2T and phylogenically closest members were below the threshold values for species delineation. The polyphasic taxonomic features illustrated in this study clearly implied that strain DKR-2T represents a novel species in the genus Kaistella, for which the name Kaistella soli sp. nov. is proposed with the type strain DKR-2T (= KACC 22070T = NBRC 114725T).

ABSTRACT Extreme and unusual ecosystems such as isolated ancient caves are considered as potential tools for the discovery of novel natural products with biological activities. Acti- nobacteria that inhabit these unusual ecosystems are examined as a promising source for the development of new drugs. In this study we focused on the preliminary estimation of fatty acid composition and antibacterial properties of culturable actinobacteria isolated from water surface of underground lakes located in Badzheyskaya and Okhotnichya caves in Siberia. Here we present isolation of 17 strains of actinobacteria that belong to the Streptomyces, Nocardia and Nocardiopsis genera. Using assays for antibacterial and antifungal activities, we found that a number of strains belonging to the genus Streptomyces isolated from Badzheyskaya cave demonstrated inhibition activity against Submitted 23 May 2018 bacteria and fungi. It was shown that representatives of the genera Nocardia and Accepted 24 September 2018 Nocardiopsis isolated from Okhotnichya cave did not demonstrate any tested antibiotic Published 25 October 2018 properties. However, despite the lack of antimicrobial and fungicidal activity of Corresponding author Nocardia extracts, those strains are specific in terms of their fatty acid spectrum. -

Streptomyces Sannurensis Sp. Nov., a New Alkaliphilic Member of the Genus Streptomyces Isolated from Wadi Sannur in Egypt

Accepted 19 April, 2011 The taxonomic position of an actinomycete isolated from a soil sample collected from Wadi Sannur in Egypt was established using a polyphasic approach. The isolate, which was designated WS 51T, was shown to have chemical and morphological properties typical of streptomycetes. An almost complete 16S rDNAgene sequence of the strain was generated and compared with corresponding sequences of representative streptomycetes. The resultant data confirmed the classification of the strain in the genus Streptomyces but also showed that it formed a distinct phyletic line within the 16S rDNAStreptomyces gene tree. The organism was most closely associated to the type strains of Streptomyces hygroscopicus, Streptomyces malaysiensis and Streptomyces yatensis but was readily separated from them using a range of phenotypic properties. It is proposed that strain WS 51T (= CCTCC 001032T = DSM 41834T) be classified in the genus Streptomyces as Streptomyces sannurensis sp. -

The large-scale production of insulin was made the history of biotechnology. The microbial cultures are managed, monitored and maintained for their genotype/phenotype stability. Bacteria are one of the biotechnologically important microbes for example Escherichia coli, some species of lactic acid bacteria, and some viruses Using such as bacteriophages etc. recognized as anti-cancer oncolytic viruses. Moreover, yeast has also been used with broad-spectrum applications, such as Saccharomyces cerevisiae. biologically active primary and secondary metabolites like ethanol and antibiotics have been diverse genetic technologies, a number of beneficial products like microbial polymers, produced so far and used.

This strain was found to produce a new hydroxamic acid-contain- ing molecule with interesting antimicrobial activities towards various multidrug-resistant micro-organ- isms. Although hydroxamic acid-containing molecules are known to exhibit low toxicities in general, only real evaluations of the toxicity levels could decide on the applications for which this new molecule is potentially most appropriate. Thus, this article provides a new framework of research. Keywords Abstract antimicrobial activity, hydroxamic acid, Streptomyces, structure elucidation, During screening for potentially antimicrobial actinobacteria, a highly taxonomy. antagonistic strain, designated WAB9, was isolated from a Saharan soil of Algeria.

Conditions caused by climate change require global efforts to be improved, but others like soil degradation demand local management. For many years, saline soils were not a problem; indeed, natural salinity shaped different biomes around the world. However, overall saline soils present adverse conditions for plant growth, which then translate into limitations for agriculture. Shortage on the surface of productive land, either due to depletion of arable land or to soil degradation, represents a threat to the growing worldwide population. Hence, the need to use degraded land leads scientists to think of recovery alternatives. -

Volatile organic compounds (VOCs) produced by nine Streptomyces spp., some of which are of industrial importance, were collected and identified using gas chromatography–mass spectrometry (GC-MS). Biosynthetic gene clusters (BGCs) present in the genomes of the respective Streptomyces spp. were also predicted to match them with the VOCs detected. Overall, 33 specific VOCs were identified, of which the production of 16 has not been previously reported in the Streptomyces. Among chemical classes, the most abundant VOCs were terpenes, which is consistent with predicted biosynthetic capabilities. In addition, 27 of the identified VOCs were plant-associated, demonstrating that some Streptomyces spp. -

Received: 16 May 2019; Accepted: 9 August 2019; Published: 19 August 2019 Abstract: A GH49 dextranase gene DexKQ was cloned from marine bacteria Arthrobacter oxydans KQ11. It was recombinantly expressed using an Escherichia coli system. Recombinant DexKQ dextranase of 66 kDa exhibited the highest catalytic activity at pH 9.0 and 55 ◦C. kcat/Km of 1 1 recombinant DexKQ at the optimum condition reached 3.03 s− µM− , which was six times that of 1 1 commercial dextranase (0.5 s− µM− ). DexKQ possessed a Km value of 67.99 µM against dextran T70 substrate with 70 kDa molecular weight. Thin-layer chromatography (TLC) analysis showed that main hydrolysis end products were isomalto-oligosaccharide (IMO) including isomaltotetraose, isomaltopantose, and isomaltohexaose. When compared with glucose, IMO could significantly improve growth of Bifidobacterium longum and Lactobacillus rhamnosus and inhibit growth of Escherichia coli and Staphylococcus aureus. -
