“…At the same time, it is similar in its features to bacteria of the genera Collimonas and Massilia only in the shape of cells, motility, Gram staining, the presence of catalase, and the relation to oxygen ( Table 1). Other signs differ or are not given in the literature [45][46][47][48][49][50].…”

“…Representatives of the genus Duganella, forming a blue-purple pigment, form wrinkled, slightly leathery colonies on agar nutrient medium (Table 1), while a flocculent sediment is observed in a liquid one [16,[42][43][44]. Literature data on the cultural properties of the genera Collimonas and Massilia under consideration are not given in the sources [45][46][47][48][49][50]. Thus, based on the literature data, the cultural properties of JF4 in a liquid nutrient medium are similar to those of Chromobacterium sp., Iodobacter sp., and Janthinobacterium sp., as they form a purple ring along the vessel wall at the interface.…”

Violacein is a biotechnologically significant secondary metabolite due to its antibacterial, antifungal, and other properties. Isolation, research, and identification of violacein producing strains are of interest for the development of biotechnological processes, in order to enhance the biosynthesis of this compound. The purpose of the present work was to study the properties of a newly isolated bacterium capable of synthesizing blue-purple pigment. An aboriginal bacterium was isolated from the coastal zone of the Vezelka River in the city of Belgorod. Based on chemical and spectrophotometric studies of the crude ethanol extract, the pigment was identified as violacein, and the isolate was assigned to the group of violacein-forming bacteria, which includes bacteria of the genera Chromobacterium, Iodobacter, Janthinobacterium, Duganella, Collimonas, and Massilia. Based on cultural, morphological, tinctorial, physiological, and biochemical properties, as well as analysis of the 16S rRNA gene sequence, the new isolated strain was assigned to the genus Janthinobacterium. The isolated strain is capable of suppressing the growth of a number of fungal and bacterial phytopathogens. For representatives of the genus Janthinobacterium, their inhibitory influence on cyanobacteria was shown for the first time.

The present study highlights the biosynthesis of silver nanoparticles (AgNPs) using culture supernatant of Massilia sp. MAHUQ-52 as well as the antimicrobial application of synthesized AgNPs against multi-drug resistant pathogenic Klebsiella pneumoniae and Salmonella Enteritidis. Well-defined AgNPs formation occurred from the reaction mixture of cell-free supernatant and silver nitrate (AgNO3) solution within 48 h of incubation. UV-visible spectroscopy analysis showed a strong peak at 435 nm, which corresponds to the surface plasmon resonance of AgNPs. The synthesized AgNPs were characterized by FE-TEM, EDX, XRD, DLS and FT-IR. From FE-TEM analysis, it was found that most of the particles were spherical shape, and the size of synthesized nanoparticles (NPs) was 15–55 nm. EDX spectrum revealed a strong silver signal at 3 keV. XRD analysis determined the crystalline, pure, face-centered cubic AgNPs. FT-IR analysis identified various functional molecules that may be involved with the synthesis and stabilization of AgNPs. The antimicrobial activity of Massilia sp. MAHUQ-52 mediated synthesized AgNPs was determined using the disk diffusion method against K. pneumoniae and S. Enteritidis. Biosynthesized AgNPs showed strong antimicrobial activity against both K. pneumoniae and S. Enteritidis. The MICs of synthesized AgNPs against K. pneumoniae and S. Enteritidis were 12.5 and 25.0 μg/mL, respectively. The MBC of biosynthesized AgNPs against both pathogens was 50.0 μg/mL. From FE-SEM analysis, it was found that the AgNPs-treated cells showed morphological changes with irregular and damaged cell walls that culminated in cell death.

“…Cell morphology and the presence of agella were determined by light microscopy (ECLIPSE E200, Nikon) and transmission electron microscopy (Hitachi H-7650) using cells grown on R2A agar medium at 28 o C for 72 h. The cell motility was established by observing the growth and diffusion of cells in the medium of semi-solid R2A containing 0.3 % agar at 20 o C incubation for 48 h (Yang et al 2019). Growth of strain NEAU-DD11 T was tested on R2A agar, Luria-Bertani agar (5 g yeast extract, 10 g tryptone, 10 g NaCl, 20 g agar and 1 l distilled water) and nutrient agar (5 g peptone, 3 g meat extracts, 15 g agar, 1 l distilled water, (Cao et al 2020;Zhao et al 2019).…”

“…The DNA G + C contents range from 62.4 to 69.4 %. At present, the genus Massilia contains a total of 55 species with validly published names (https://www.bacterio.net/genus/massilia), including the recently described species Massilia arenosa (Rachel et al 2020), Massilia atriviolacea (Yang et al 2019) and Massilia aquatica (Lu et al 2020). Members of the genus were isolated from various sources, such as soil (Chaudhary et al 2017;Singh et al 2015;Zu et al 2008;Kim 2014;Zheng et al 2017), air (Weon et al 2008(Weon et al , 2009, water (Gallego et al 2006), ice core (Shen et al 2013;Guo et al 2016), glacier permafrost (Wang et al 2018), rock surface (Sun et al 2017) and a human clinical specimen (Kämpfer et al 2008(Kämpfer et al , 2012.…”

A bacterial strain, Gram-stain negative, rod-shaped, aerobic and cellulose-degrading, designated NEAU-DD11T, was isolated from rhizosphere soil of rice collected from Northeast Agricultural University in Harbin, Heilongjiang province, North-east China. Base on 16S rRNA gene sequence analysis, strain NEAU-DD11T belongs to the genus Massilia and shared high sequence similarities with Massilia phosphatilytica 12-OD1T (98.46 %) and Massilia putida 6NM-7T (98.41 %). Phylogenetic analysis based on the 16S rRNA gene and whole genome sequences indicated that strain NEAU-DD11T formed a stable cluster with M. phosphatilytica 12-OD1T and M. putida 6NM-7T. The major fatty acids of the strain were C16:0, C17:0-cyclo and C16:1ω7c. The respiratory quinone was Q-8. The polar lipids profile of the strain showed the presence of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentified polar lipid and an unidentified phospholipid. In addition, the digital DNA-DNA hybridization values between strain NEAU-DD11T and M. phosphatilytica 12-OD1T and M. putida 6NM-7T were 45.4% and 35.6%, respectively, which are lower than the accepted threshold value of 70%. The DNA G + C content of strain NEAU-DD11T was 66.2 %. The whole genome analysis showed the strain contained carbohydrate enzymes such as glycoside hydrolase and polysaccharide lyase, which enabled the strain to had the function of degrading cellulose. On the basis of the phenotypic, genotypic and chemotaxonomic characteristics, strain NEAU-DD11T represents a novel species of the genus Massilia, for which the name Massilia cellulosiltytica sp. nov. is proposed. The type strain is NEAU-DD11T (= CCTCC AB 2019141T = DSM 109721T).
