General plant diseases as well as soil-borne pathogens severely reduce agricultural yield. The rhizosphere (the region of the soil that includes and surrounds the roots) is an important niche for microbial diversity in particular phytobeneficial bacteria including plant growth-promoting rhizobacteria (PGPR) which have been used for a very long time to combat plant diseases. Pathogen control and crop

Antimicrobial activity of coral-associated beneficial bacteria against coral disease-causing microbial pathogens J. Basic Microbiol. (IF 3.1) Pub Date : 2023-09-19 Lawrance Irudayarajan, Chinnarajan Ravindran, Haritha P. Raveendran
Microbial infection of immune-compromised corals influences disease severity, resulting in coral mortality. However, coral-associated beneficial bacteria are known to produce antimicrobial compounds that prevent the growth of potential pathogens and invading microbes. Hence, beneficial bacteria associated with coral Porites lutea were isolated and antimicrobial protein and bioactive secondary metabolites

The effect of photodynamic therapy in controlling the oral biofilm: A comprehensive overview J. Basic Microbiol. (IF 3.1) Pub Date : 2023-09-19 Seyedeh Sara Aghili, Alireza Jahangirnia, Mostafa Alam, Asal Bagherzadeh Oskouei, Mohsen Golkar, Ashkan Badkoobeh, Kamyar Abbasi, Meysam Mohammadikhah, Shahryar Karami, Reza Sayyad Soufdoost, Reza Abdollahi Namanloo, Sahar Talebi, Samira Amookhteh, Maryam Hemmat, Sima Sadeghi
Several resistance mechanisms are involved in dental caries, including oral biofilms. An accumulation of bacteria on the surface of teeth is called plaque. Periodontitis and gingivitis are caused by dental plaque. In this review article, we aimed to review the studies associated with the application of photodynamic therapy (PDT) to prevent and treat various microbial biofilm-caused oral diseases in

Bioprospecting the potential of metabolites from a Saharan saline soil strain Nocardiopsis dassonvillei GSBS4 J. Basic Microbiol. (IF 3.1) Pub Date : 2023-09-18 Ibtissem Djinni, Leah Conroy, Mihayl Varbanov, Samiha Souagui, Betitera Yanat, Andrea Defant, Mouloud Kecha, Ines Mancini
Saharan soil samples collected in El-Oued province have been investigated for actinobacteria as a valuable source for the production of bioactive metabolites. A total of 273 isolates were obtained and subjected to antagonistic activity tests against human pathogenic germs. A strain with a broad-spectrum antimicrobial activity was selected and identified as Nocardiopsis dassonvillei GSBS4, with high

AaLaeA targets AaFla1 to mediate the production of antitumor compound in Alternaria alstroemeria J. Basic Microbiol. (IF 3.1) Pub Date : 2023-09-17 Can Feng, Wen Zheng, Long Han, Jian-kang Wang, Xing-ping Zha, Qing Xiao, Zhang-jiang He, Ji-chuan Kang
Endophytic fungi are an important source of novel antitumor substances. Previously, we isolated an endophytic fungus, Alternaria alstroemeria, from the medicinal plant Artemisia artemisia, whose crude extracts strongly inhibited A549 tumor cells. We obtained a transformant, namely AaLaeAOE26, which completely loses its antitumor activity due to overexpression of the global regulator AaLaeA. Re-sequencing

Changes of microbiome in response to supplements with silver nanoparticles in cotton rhizosphere J. Basic Microbiol. (IF 3.1) Pub Date : 2023-09-17 Abhijeet Joshi, Radhika Joshi, Prushti Koradiya, Hetvi Vank
The current study focuses on analyzing the effects of supplements containing silver nanoparticles (AgNPs) on plant growth and rhizospheric bacterial communities. Specifically, the impact of AgNP supplements was assessed on both plant growth promoting traits and bacterial communities in the soil. To do this, a screening process was conducted to select bacteria capable of synthesizing AgNPs through extracellular
