Temperature-Dependent tRNA Modifications in Bacillales

open access: yesInternational Journal of Molecular Sciences
Transfer RNA (tRNA) modifications are essential for the temperature adaptation of thermophilic and psychrophilic organisms, as they control the rigidity and flexibility of transcripts. To further understand how specific tRNA modifications are adjusted to maintain functionality in response to temperature fluctuations, we investigated whether tRNA ...

Biological Activity of Bacillus thuringiensis (Bacillales: Bacillaceae) in Anastrepha fraterculus (Diptera: Tephritidae)

Journal of Economic Entomology, 2018
Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is considered to be one of the major pest insects in fruit orchards worldwide. Bacillus thuringiensis Berliner (Bacillales: Bacillaceae) strains are widely used as biological control agents and show high biological activity against different insect species.

Identification and classification of known and putative antimicrobial compounds produced by a wide variety of Bacillales species [PDF]

open access: yesBMC Genomics, 2016
Gram-positive bacteria of the Bacillales are important producers of antimicrobial compounds that might be utilized for medical, food or agricultural applications. Thanks to the wide availability of whole genome sequence data and the development of specific genome mining tools, novel antimicrobial compounds, either ribosomally- or non-ribosomally ...

Bioactivity of Bacillus thuringiensis (Bacillales: Bacillaceae) on Diatraea saccharalis (Lepidoptera: Crambidae) eggs

Pest Management Science, 2021
AbstractBACKGROUNDBacillus thuringiensis (Bt) is a Gram‐positive bacterium that synthesizes specific protein toxins, which can be exploited for control of various insect pests, including Diatraea saccharalis, a lepidopteran that severely damages sugarcane crops. Although studies have described the effects of Bt in the larval phases of D.

Phylogenetic diversity of aerobic spore-forming Bacillalles isolated from Brazilian soils

International Microbiology, 2019
The phylum Firmicutes comprises seven classes where most species are either aerobic or anaerobic endospore former. Inside Firmicutes, species allocated in the genus Bacillus and related genera are collectively named aerobic endospore-forming bacteria (AEFB), and the soil is their major reservoir.

Germination of Spores of the Orders Bacillales and Clostridiales

Annual Review of Microbiology, 2017
Dormant Bacillales and Clostridiales spores begin to grow when small molecules (germinants) trigger germination, potentially leading to food spoilage or disease. Germination-specific proteins sense germinants, transport small molecules, and hydrolyze specific bonds in cortex peptidoglycan and specific proteins.

Ultrastructural analysis of spores from diverse Bacillales species isolated from Brazilian soil

Environmental Microbiology Reports, 2018
Summary Many species in the order Bacillales form a specialized cell type called a spore that is resistant to a range of environmental stresses. Transmission electron microscopy (TEM) reveals that the spore is comprised of a series of concentric shells, surrounding an ...

A regulatory RNA required for antitermination of biofilm and capsular polysaccharide operons in Bacillales.

Molecular microbiology, 2010
Formation of a Bacillus subtilis biofilm community requires an abundant matrix protein, TasA and an exopolysaccharide. The transcriptional regulatory pathways that control synthesis of these structural features are complex and responsive to multiple physiological and population signals.

Synergistic Antibacterial Activity of Ecklonia cava (Phaeophyceae: Laminariales) against Listeria monocytogenes (Bacillales: Listeriaceae)

Fisheries and aquatic sciences, 2015
In an effort to discover alternative antimicrobials against Listeria monocytogenes, several marine algae were screened. The methanolic extract of Ecklonia cava exhibited the highest antibacterial activity against L. monocytogenes, with the ethyl acetate (EtOAc) soluble fraction of E.

BACILLALES INFLUENCE QUALITY AND SAFETY OF DAIRY PRODUCTS

2017
Bacillales, an order of Gram-positive bacteria, are commonly isolated from dairy foods and at various points along the dairy value chain. Three families of Bacillales are analyzed in this work: (i) Listeriaceae (represented by Listeria monocytogenes), (ii) Paenibacillaceae (represented by Paenibacillus), and (iii) Bacillaceae (represented by the ...
