Genomic and Phenomic Analysis of a Marine Bacterium, Photobacterium marinum J15
Publication date: Available online 9 January 2020Source: Microbiological ResearchAuthor(s): Noordiyanah Nadhirah Roslan, Mohamad Syazwan Ngalimat, Adam Thean Chor Leow, Siti Nurbaya Oslan, Syarul Nataqain Baharum, Suriana SabriAbstractPhotobacterium species are widely distributed in the marine environment. The overall metabolism of this genus remains largely unknown. In order to improve our knowledge on this bacterium, the relationship between the genome and phenome of the Photobacterium isolate was analyzed. The cream colored, Gram-negative, rod-shaped and motile bacterial strain, J15, was isolated from marine water of Ta...

Beneficial effect of GABA-rich fermented milk on insomnia involving regulation of gut microbiota
In this study, milk was fermented with Lactobacillus brevis DL1-11, a strain with high GABA-producing capacity. The potential beneficial effects of this fermented milk on anxiety and sleep quality were evaluated in animal experiments. Sixty mice were divided into control, non-GABA fermented milk (NGFM), low-dose GABA fermented milk (LGFM, 8.83 mg/kg.bw), medium-dose GABA fermented milk (MGFM, 16.67 mg/kg.bw), high-dose GABA fermented milk (HGFM, 33.33 mg/kg.bw) and diazepam groups. The results of open field test and elevated plus-maze test indicated decreases in anxiety behavior after oral HGFM administration. Moreov...

Revealing the impact of global mass bleaching on coral microbiome through 16S rRNA gene-based metagenomic analysis
Publication date: Available online 31 December 2019Source: Microbiological ResearchAuthor(s): Ramu Meenatchi, Thangadurai Thinesh, Pownraj Brindangnanam, Saqib Hassan, George Seghal Kiran, Joseph SelvinAbstractCoral bleaching, a phenomenon by which the expulsion of corals’ alveolate endosymbiont (zooxanthellae) occurs when experiencing thermal stress is the major cause for devastation of corals. However, apart from this obligate symbiont of Scleractinian corals, there are different kinds of microbes that exist as stable, transient or sporadic members of the holobiont which resides within various microhabitats in the cora...

Bacterial line of defense in Dirinaria lichen from two different ecosystems: First genomic insights of its mycobiont Diriniria sp. GBRC AP01
Publication date: Available online 28 December 2019Source: Microbiological ResearchAuthor(s): Apurvasinh C. Puvar, Neelam M. Nathani, Inayatullah Shaikh, Arpan D. Bhatt, Poonam Bhargava, Chaitanya G. Joshi, Madhvi N. JoshiAbstractLichens have been widely studied for their symbiotic properties and for the secondary metabolites production by its fungal symbiont. Recent molecular studies have confirmed coexistence of bacteria along with the fungal and algal symbionts. Direct nucleic acid study by -omics approaches is providing better insights into their structural and functional dynamics. However, genomic analysis of individu...

Selected isolates of Trichoderma gamsii induce different pathways of systemic resistance in maize upon Fusarium verticillioides challenge
Publication date: Available online 19 December 2019Source: Microbiological ResearchAuthor(s): Stefania Galletti, Roberta Paris, Stefano CianchettaAbstractThe pink ear rot is one of the most damaging maize diseases, caused by the mycotoxigenic fungal pathogen, Fusarium verticillioides. The application of biological control agents, like antagonistic and/or resistance inducer microorganisms, is an option to reduce fungal infection and kernel contamination in a sustainable and environmentally friendly way. It is well known that Trichoderma species are non-pathogenic fungi able to antagonize plant pathogens and to induce system...
