Peningkatan produksi udang vaname ( L. vannamei ) menyebabkan kebutuhan akan benih unggul juga semakin meningkat. Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan probiotik yang berbeda terhadap tingkat kelulushidupan dan mampu memberikan hasil terbaik. Penelitian dilakukan selama 17 hari, dimulai dari stadia nauplius hingga post larva (PL-10). Jenis eksperimen dengan menggunak...

Paenibacillus polymyxa strain YC0573 is a plant growth-promoting rhizobacterium with antimicrobial activity, which was isolated from tobacco rhizosphere. Here, we report the complete genome sequence of P. polymyxa YC0573. Antifungal and antibacterial genes were discovered.

Plant-associated bacteria fulfill important functions for plant growth and health. However, our knowledge about the impact of bacterial treatments on the host's microbiome and physiology is limited. The present study was conducted to assess the impact of bacterial inoculants on the microbiome of chamomile plants Chamomilla recutita (L.) Rauschert grown in a field under organic management in Egy...

Paenibacillus polymyxa, a Gram-positive low-G+C spore-forming soil bacterium, belongs to the plant growth-promoting rhizobacteria. The swarming motility of P. polymyxa strain E681 was greatly induced by a secondary metabolite, citrinin, produced by Penicillium citrinum KCTC6549 in a dose-dependent manner at concentrations of 2.5-15.0 microg mL(-1) on tryptic soy agar plates containing 1.0% (w/v...

In the present study, a total of 186 bacterial strains isolated from various soil sources and plant species from Eastern Anatolia region in Turkey were evaluated for their ability to suppress gray mold (Botrytis cinerea Pers. ex Fr.) occurred on strawberry cv. Fern. Among 186 bacterial strains, 36 were found effective to inhibit of development B. cinerea under in vitro conditions, and thirteen ...

Polymyxin E, produced by Paenibacillus polymyxa, is an important antibiotic normally against Gram-negative pathogens. In this study, we found that polymyxin E can kill its producer P. polymyxa, a Gram-positive bacterium, by disrupting its cell membrane. Membrane damage was clearly revealed by detecting the leakage of intracellular molecules. The observation using scanning electron microscopy al...

The reduction of NAD catalyzed by pig heart mitochondrial malate dehydrogenase can be stimulated by low concentrations, approximately 0.05 mM, of Hg-‘+. This activation is dependent on the presence of the substrate malate at the time the enzyme is exposed to Hg-‘-+. The stimulation is both pHand temperature-dependent, with maximum stimulation occurring near pH 8.8 and 30”. The activation is not...
