Bacillus | Definition, Features, & Types | Britannica
Bacillus, any of a genus of rod-shaped, gram-positive, aerobic or (under some conditions) anaerobic bacteria widely found in soil and water. Some types of Bacillus bacteria are harmful to humans, plants, or other organisms. Learn about the features and types of …
Bacillus - Wikipedia
Bacillus (Latin "stick") is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum Bacillota, with 266 named species. The term is also used to describe the shape (rod) of other so-shaped bacteria; and the plural Bacilli is the name of the class of …
Bacterial cell structure - Wikipedia
Cell shape is generally characteristic of a given bacterial species, but can vary depending on growth conditions. Some bacteria have complex life cycles involving the production of stalks and appendages (e.g. Caulobacter) and some produce elaborate structures bearing reproductive spores (e.g. Myxococcus, Streptomyces).

Oct 10, 2024 · Explore the unique morphology and cellular adaptations of Bacillus, highlighting its survival strategies and genetic versatility. Bacillus bacteria are a fascinating group of microorganisms known for their rod-like shape and ability to adapt to various environments.
Discuss the factors that determine the size and shape of a bacterial cell. Describe the fluid mosaic model of membrane structure and identify the types of lipids typically found in bacterial membranes. Distinguish macroelements (macronutrients) from micronutrients (trace elements) and provide examples of each.
Bacillus - Medical Microbiology - NCBI Bookshelf
Bacillus species are aerobic, sporulating, rod-shaped bacteria that are ubiquitous in nature. Bacillus anthracis, the agent of anthrax, is the only obligate Bacillus pathogen in vertebrates. Bacillus larvae, B lentimorbus, B popilliae, B sphaericus, and B thuringiensis are pathogens of specific groups of insects.

Bacteria - Definition, Structure, Diagram, Classification - BYJU'S
Bacteria can be classified based on shape, mode of nutrition, respiration, the composition of the cell wall, etc. Based on these criteria, bacteria can be classified as bacillus, coccus or vibrio, etc., autotrophic or heterotrophic, aerobic or anaerobic, Gram + or Gram -.
Chapter 2: Structure of Bacterial Cells - McGraw Hill Medical
Sizes of representative bacteria, viruses, yeasts, protozoa, and human red cells. The bacteria range in size from Mycoplasma, the smallest, to Bacillus anthracis, one of the largest. The viruses range from poliovirus, one of the smallest, to poxviruses. Yeasts, such as Candida albicans, are generally larger than bacteria. Protozoa have many ...
