Paenibacillus arachidis sp. nov., isolated from groundnut seeds

Abstract

A Gram-stain-positive, endospore-forming, rod-shaped, facultatively anaerobic bacterium, designated as strain E3T , was isolated from groundnut seeds.

In vitro Evaluation of Groundnut (Arachis hypogea L.) Rhizospheric Bradyrhizobium Traits for Dinitrogen Fixation

“…Numerous researchers, including Agah et al [10] and Didagde et al [11] have documented the presence of Bradyrhizobium in various niches like soils, roots, and the rhizosphere of diverse crops, including groundnut. Groundnut rhizosphere's ubiquity as a habitat for Bradyrhizobium has been reported by Didagbe [11] and Sadaf et al [12]. The relative size of this population, as a percentage of the total soil bacterial population, has been quantified as 1 to 10% according to Kalaiarasi and Dinakar [13].…”

“…The relative size of this population, as a percentage of the total soil bacterial population, has been quantified as 1 to 10% according to Kalaiarasi and Dinakar [13]. Additionally, Silva et al [14] and Sadaf et al [12] have affirmed the presence of Bradyrhizobium as a plant growth-promoting rhizobacterium (PGPR) in both groundnut rhizosphere and nodules. Modern high-throughput techniques encompassing Omics sciences have also enabled the estimation of overall microbial populations, as noted by Aravinthkumar et al [15].…”

Paenibacillus cymbidii sp. nov., isolated from Cymbidium goeringii roots

“…Members of the genus Paenibacillus have been isolated from diverse environments, of which plants are important sources. Since 2016, 14 species validly published in the IJSEM were associated with plants, including Paenibacillus cucumis isolated from a cucumber plant [3], Paenibacillus silagei isolated from corn silage [4], Paenibacillus arachidis isolated from groundnut seeds [5], Paenibacillus hispanicus isolated from Triticum aestivum roots [6], Paenibacillus oryzae isolated from rice roots [7], Paenibacillus sinopodophylli isolated from roots of Sinopodophyllum hexandrum [8], Paenibacillus methanolicus isolated from the phyllosphere of bamboo [9], Paenibacillus nebraskensis isolated from the root surface of field-grown maize [10], Paenibacillus polysaccharolyticus isolated from leaves of bamboo Phyllostachys aureosulcata [11], Paenibacillus qinlingensi s isolated from roots of Sinopodophyllum hexandrum [12], Paenibacillus tritici isolated from wheat roots [13], Paenibacillus paeoniae isolated from leaf of Paeonia lactiflora Pall [14], Paenibacillus thalictri isolated from surface-sterilized tissue of Thalictrum simplex L. [15] and Paenibacillus paridis isolated from the root of Paris polyphylla [16]. In this study, a bacterial strain was isolated from surface-sterilized roots of Cymbidium goeringii and identified via the characteristics recommended in the minimal standards for aerobic endospore-forming bacteria by using a polyphasic approach [17].…”

Microbacterium humicola sp. nov., Microbacterium terrisoli sp. nov., Paenibacillus pedocola sp. nov., Paenibacillus silviterrae sp. nov., Flavobacterium terrisoli sp. nov., and Aquabacterium humicola sp. nov., isolated from soil

“…Members of the genus Microbacterium were obtained from diverse environments, such as cow dung, gut, plant, soil, sediment, water, compost, insect, and milk products [2,3,[12][13][14][15][16][17][18]. Paenibacillus has been isolated from various habitats, including soil, sediment, hot springs, eutrophic lake, freshwater, mountain, air, rhizosphere, phyllosphere, seeds, plants, food, insects, necrotic wound, and faeces [7,[19][20][21][22][23][24][25][26]. Flavobacterium species are abundant in soil ecosystems [27], freshwater [28], seawater [29], glaciers [30], decaying wood [9], plants [31], fish [32], and penguins [33]; whereas, most of the Aquabacterium species have been isolated from aquatic habitats, including a drinking water system [11], spring water [34], a freshwater pond [35], and a river [36].…”
