“…isolated by Lee et al (2007), with similarities as a Grampositive rod, does not form spores, and is immobile (0.6-0.8×1.4-2.1 μm) colonies of opaque, convex, circular and pale yellow cells with an entire margin, and reaching a diameter of about 1.0-1.5 mm. On the other hand, research by Jun et al (2021) claims a new species from the genus Nocardioides isolated from kaolinite, is gram-positive, nonmotile, rod-shaped, and short bacterium.This bacterium is also found in the rhizosphere of corn (Yang et al 2017). It belongs to the Actinobacteria genera, which are abundant in soil and water ecosystems and play an important role in decomposition.…”

Abstract. Sukmawati, Rahim I, Harsani, Syafnur A, Arodhiskara Y, Selao A, Anisa LFN. 2023. A new strain of bacteria isolated from chemically saturated corn rhizosphere under the dominance of the mineral kaolinite. Biodiversitas 24: 1886-1894. The kaolinite mineral that dominates the cornfield reduces soil fertility and the bacterial community. The discovery of adaptive bacterial strains on kaolinite dominant land is a biological strategy to improve soil fertility because it is part of the root ecosystem. This study aims to obtain adaptive and superior bacteria in producing IAA hormones and fixing nitrogen. The soil analysis method uses X-Ray Diffraction (XRD) and X-Ray Fluorescence (XRF) analysis to characterize clay minerals and soil chemical content. While the bacterial characterization was carried out morphologically and physiologically. After that, followed by the 16S rRNA gene sequence analysis. The type of kaolinite clay mineral dominates the soil samples with a SiO2 content of >40%. A total of 17 bacterial isolates were purified, 12 had round colony shapes, and 5 had irregular shapes dominated by cream color, 11 of which were identified as Gram-positive and 6 Gram-negative bacteria. RJ1T isolates/isolated produced the highest auxin (0.141 mgL-1), while RJ1P isolates/isolated had the highest nitrogen fixation ability (0.975%) and were not pathogenic. The isolates were closely related to the Nocardioides marinisabuli strain RA2816S ribosomal RNA gene (99.57%). Thus, RJ1PI bacterial isolate is an adaptive bacteria that can be formulated as a biological agent to increase maize productivity in the dry land.

“…Methylophilaceae is the dominant microbial type in oxygen-rich culture environments containing nitrate ( Beck et al, 2013 ; Chistoserdova et al, 2013 ). Nocardioidaceae and Alicyclobacillaceae members of these two families are reported to be linked to decomposition activity ( Packard et al, 2019 ; Yoon et al, 2021 ). Previous studies have also found that the fungal genera Penicillium and Chaetomium , which are important decomposers, were enriched in the unique microbiomes of RSD-treated soil ( Zhao et al, 2018 ; Huang et al, 2019 ).…”

Reductive soil disinfestation (RSD) and soil fumigant chloropicrin (SFC) are two common agricultural strategies for the elimination of soil-borne pathogens. However, the differences in soil environmental factors, soil bacterial microbiome, and root performance between SFC and RSD are poorly understood. In this study, three soil treatments, untreated control (CK), SFC with 0.5 t⋅ha–1 chloropicrin, and RSD with 15 t⋅ha–1 animal feces, were compared. We evaluated their effects on soil environmental factors, bacterial community structure, and root activity using chemical analysis and high-throughput sequencing. RSD treatment improved soil composition structure, bacterial diversity, and root performance to a greater extent. Carbon source utilization preference and bacterial community structure were strikingly altered by SFC and RSD practices. Bacterial richness, diversity, and evenness were notably lowered in the SFC- and RSD-treated soil compared with the CK-treated soil. However, RSD-treated soil harbored distinct unique and core microbiomes that were composed of more abundant and diverse potentially disease-suppressive and organic-decomposable agents. Also, soil bacterial diversity and composition were closely related to soil physicochemical properties and enzyme activity, of which pH, available Na (ANa), available Mg (AMg), available Mn (AMn), total Na (TNa), total Ca (TCa), total Cu (TCu), total Sr (TSr), urease (S-UE), acid phosphatase (S-ACP), and sucrase (S-SC) were the main drivers. Moreover, RSD treatment also significantly increased ginseng root activity. Collectively, these results suggest that RSD practices could considerably restore soil nutrient structure and bacterial diversity and improve root performance, which can be applied as a potential agricultural practice for the development of disease-suppressive soil.
