4 days ago · First, bacterial cultures were spotted between two lines of 1-day-grown A. niger mycelia. The ancestor bacterium grew and created a small colony almost surrounded by the fungus after 7 days (Fig ...
2 days ago · Cyanobacteria use photosynthetic pigments, such as various forms of chlorophyll, carotenoids, phycobilins to convert the energy in sunlight to chemical energy. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed.

1 day ago · Detected colony-forming-units were standardized to colony-forming-units per milliliter to allow quantification. As the total homogenization volumes including the ant, the beads and the buffer were close to 1 milliliter, the obtained values can be considered as surrogates for the total number of vital and culturable microorganisms per ant.
4 days ago · Bacteria that produce lecithinase hydrolyze the lecithin and a zone of white precipitate forms around the colonies. B. cereus is typically mannitol-negative, produce pink-red colonies in MYP agar with a zone of precipitate around the colonies, indicating lecithinase-positive activity.
