bakterieens
Bakterieens refers to bacteria, a vast and diverse group of unicellular microorganisms. Most bacteria are prokaryotes, lacking a defined nucleus. They range from 0.2 to 100 micrometers and have a cell membrane and wall, often with peptidoglycan that helps distinguish Gram-positive from Gram-negative species.
Bacteria exhibit shapes such as cocci (spherical), bacilli (rod-shaped), and spirilla or spirochetes (spiral). They live
Their metabolism is diverse. Some are phototrophs that harvest light; others are chemotrophs that derive energy
Bacteria play essential roles in ecosystems and human life. They drive decomposition and nutrient cycling, fix
Studying bacteria involves microscopy, culturing on selective media, biochemical tests, and genetic sequencing. Understanding bacterial diversity
