Bacteriocins: potentials and prospects in health and agrifood systems
Arch Microbiol. 2024 Apr 25;206(5):233. doi: 10.1007/s00203-024-03948-y.ABSTRACTBacteriocins are highly diverse, abundant, and heterogeneous antimicrobial peptides that are ribosomally synthesized by bacteria and archaea. Since their discovery about a century ago, there has been a growing interest in bacteriocin research and applications. This is mainly due to their high antimicrobial properties, narrow or broad spectrum of activity, specificity, low cytotoxicity, and stability. Though initially used to improve food quality and safety, bacteriocins are now globally exploited for innovative applications in human, animal, an...

New insights into the coal-associated methane architect: the ancient archaebacteria
Arch Microbiol. 2024 Apr 25;206(5):234. doi: 10.1007/s00203-024-03961-1.ABSTRACTExploration and marketable exploitation of coalbed methane (CBM) as cleaner fuel has been started globally. In addition, incidence of methane in coal basins is an imperative fraction of global carbon cycle. Significantly, subsurface coal ecosystem contains methane forming archaea. There is a rising attention in optimizing microbial coal gasification to exploit the abundant or inexpensive coal reserves worldwide. Therefore, it is essential to understand the coalbeds in geo-microbial perspective. Current review provides an in-depth analysis of re...

Biotransformation activities of fungal strain apiotrichum sp. IB-1 to ibuprofen and naproxen
Arch Microbiol. 2024 Apr 25;206(5):232. doi: 10.1007/s00203-024-03963-z.ABSTRACTIbuprofen (IBU) and naproxen (NPX), as widely prescribed non-steroidal anti-inflammatory drugs (NSAIDs), are largely produced and consumed globally, leading to frequent and ubiquitous detection in various aqueous environments. Previously, the microbial transformation of them has been given a little attention, especially with the isolated fungus. A yeast-like Apiotrichum sp. IB-1 has been isolated and identified, which could simultaneously transform IBU (5 mg/L) and NPX (2.5 mg/L) with maximum efficiencies of 95.77% and 88.31%, respectively. For...

Stilbenes: a journey from folklore to pharmaceutical innovation
Arch Microbiol. 2024 Apr 22;206(5):229. doi: 10.1007/s00203-024-03939-z.ABSTRACTIn modern times, medicine is predominantly based on evidence-based practices, whereas in ancient times, indigenous people relied on plant-based medicines with factual evidence documented in ancient books or folklore that demonstrated their effectiveness against specific infections. Plants and microbes account for 70% of drugs approved by the USFDA (U.S. Food and Drug Administration). Stilbenes, polyphenolic compounds synthesized by plants under stress conditions, have garnered significant attention for their therapeutic potential, bridging anci...

Oligomerization states of the Mycobacterium tuberculosis RNA polymerase core and holoenzymes
Arch Microbiol. 2024 Apr 22;206(5):230. doi: 10.1007/s00203-024-03955-z.ABSTRACTDuring the past few decades, a wealth of knowledge has been made available for the transcription machinery in bacteria from the structural, functional and mechanistic point of view. However, comparatively little is known about the homooligomerization of the multisubunit M. tuberculosis RNA polymerase (RNAP) enzyme and its functional relevance. While E. coli RNAP has been extensively studied, many aspects of RNAP of the deadly pathogenic M. tuberculosis are still unclear. We used biophysical and biochemical methods to study the oligomerization s...

Lysinibacillus piscis sp. nov. isolated from the gut of mottled spinefoot Siganus fuscescens
Arch Microbiol. 2024 Apr 21;206(5):228. doi: 10.1007/s00203-024-03937-1.ABSTRACTA novel Lysinibacillus strain, designated KH24T, was isolated from the gut of Siganus fuscescens, a herbivorous fish, which was captured off the coast of Okinawa, Japan. Strain KH24T is a rod-shaped, Gram-stain-positive, spore-forming, and motile bacterium that forms off-white colonies. The 16S rRNA gene sequence of strain KH24T showed the highest similarity (97.4%) with Lysinibacillus pakistanensis JCM 18776T and L. irui IRB4-01T. Genomic similarities between strain KH24T and Lysinibacillus type strains, based on average nucleotide identity, d...

Biological characteristics of Cordyceps militaris single mating-type strains
This study assessed the physiology and fertility traits of six C. militaris strains with distinct origins and characteristics, focusing on single mating-type strains. The results demonstrated that the three identified strains (CMDB01, CMSY01, and CMJB02) were single mating-type possessing only one mating-type gene (MAT1-1). In contrast, the other three strains (CMXF07, CMXF09, and CMMS05) were the dual mating type. The MAT1-1 strains sourced from CMDB01, CMSY01, and CMJB02 consistently produced sporocarps but failed to generate ascospores. However, when paired with MAT1-2 strains, the MAT1-1 strains with slender fruiting b...

Growth-promoting effects of Aspergillus Elegans and the dark septate endophyte (DSE) Periconia macrospinosa on cucumber
In this study, two endophytes isolated from wild plant roots, were tested to determine their effect on the growth promotion of cucumber (Cucumis sativus L.) plants. The phylogenetic analysis revealed that the designated isolates were Aspergillus elegans and Periconia macrospinosa. The results of the Plant Growth Promoting Fungal (PGPF) tests showed that both Aspergillus elegans and Periconia macrospinosa have a zinc solubilizing capacity, especially A. elegans, with a solubilization index higher than 80%. Also, both have a high salt tolerance (10-15% NaCl for P. macrospinosa and A. elegans, respectively), cellulolytic acti...

Characterization of Bacillus amyloliquefaciens PM415 as a potential bio-preserving probiotic
Arch Microbiol. 2024 Apr 20;206(5):222. doi: 10.1007/s00203-024-03953-1.ABSTRACTAnimal feed is vulnerable to fungal infections, and the use of bio-preserving probiotics has received increasing attention. In contrast to Lactobacillus and Bifidobacteria spp., fewer Bacillus spp. have been recognized as antifungal probiotics. Therefore, our objective was to screen antifungal strains and provide more Bacillus candidates to bridge this gap. Here, we screened 56 bacterial strains for cyclic lipopeptide genes and conducted an antifungal assay with Aspergillus niger as a representative fungus. We found that a Bacillus strain Bacil...

Effects of p-coumaric acid on probiotic properties of Lactobacillus acidophilus LA-5 and lacticaseibacillus rhamnosus GG
Arch Microbiol. 2024 Apr 20;206(5):223. doi: 10.1007/s00203-024-03957-x.ABSTRACTProbiotics are defined as "live microorganisms that provide health benefits to the host when administered in adequate amounts." Probiotics have beneficial effects on human health, including antibacterial activity against intestinal pathogens, regulation of blood cholesterol levels, reduction of colitis and inflammation incidence, regulation of the immune system, and prevention of colon cancer. In addition to probiotic bacteria, some phenolic compounds found in foods we consume (both food and beverages) have positive effects on human health. p-c...

Structure and biological activity in vitro of Flagellin and its mutants from Escherichia coli Nissle 1917
This study utilized AlphaFold2, SERS (Surface-enhanced Raman spectroscopy), and CD (circular dichroism) techniques to analyze the structural characteristics of FliCEcN and its mutants, FliCΔ174-506 and FliCΔ274-406, and tested their immune effects by stimulating Caco-2 cells in vitro. The results indicate that the D2 and D3 domains of FliCEcN have more complex interactions compared to the D1-D2 domain pair., and these domains also play a role in molecular docking with TLR5 (Toll-like receptor 5). Furthermore, FliCΔ274-406 has more missing side chain and characteristic amino acid peaks than FliCΔ174-506. The FliCEcN gro...
