The key difference between fastidious and nonfastidious bacteria is that fastidious bacteria require special nutritional supplements and conditions to grow while nonfastidious bacteria do not need such special nutritional supplements or conditions. Furthermore, fastidious bacteria show slow growth in contrast to nonfastidious bacteria, which grow fast. Bacteria are tiny unicellular organisms. They are prokaryotic and […]

The key difference between chemostat and turbidostat is that a single nutrient can limit the microbial growth inside the chemostat while a single nutrient cannot control the microbial growth inside the turbidostat. Microorganisms are grown in liquid cultures in order to multiply them in a large scale. Continuous microbial culture technique is one type of […]

The key difference between Chlamydia and Rickettsia is their mode of transmission. Chlamydia transmits from person to person while Rickettsia transmits by arthropod vectors. Another main difference between Chlamydia and Rickettsia is that Chlamydia cannot produce ATP while Rickettsia can produce some ATP since they have a cytochrome system. Chlamydia and Rickettsia are two bacterial […]

The key difference between Mycoplasma and Phytoplasma is that Mycoplasmas are bacterial parasites of animals while Phytoplasmas are obligate bacterial parasites of plant phloem tissues. Mycoplasma and Phytoplasma are two bacterial groups that do not have a cell wall. Both groups include obligate parasites. Previously, phytoplasmas were known as mycoplasma-like organisms. CONTENTS 1. Overview and Key […]

The key difference between Enterococcus and Streptococcus is that Enterococci are generally nonhemolytic (gamma helolytic) while Streptococci are hemolytic (alpha and beta hemolytic). Enterococcus and Streptococcus are two genera of lactic acid bacteria. Both genera include spherical shaped bacteria that are gram-positive, non-spore forming, nonmotile cocci and facultative anaerobes. CONTENTS 1. Overview and Key Difference […]

The key difference between Aerobic and Anaerobic Microorganisms is the requirement of oxygen for the survival aerobic microorganisms while it is not for the anaerobic microorganisms. That is, the aerobic microorganisms require oxygen as their final electron acceptor during the aerobic respiration while anaerobic microorganisms do not require oxygen for their cellular respiration. The response to […]

The key difference between Pseudomonas aeruginosa and Pseudomonas fluorescens is that the P. aeruginosa is an opportunistic human pathogen while the P. fluorescens is not a human pathogen. More explicitly saying, P. aeruginosa is a pathogen of plants and animals including human whereas P. fluorescence is a plant growth promoting bacterial species. Another important difference […]

The key difference between Cyanobacteria and Proteobacteria cannot be deduced specifically. However, cyanobacteria, known as blue-green algae, are completely photosynthetic while proteobacteria compose of a wide variety of gram negative organisms out of which some organisms are photosynthetic. Even though Cyanobacteria and Proteobacteria share many characteristics in common, based on their ability to photosynthesize, they […]

The key difference between Binary Fission and Multiple Fission is that a single entity divides into two parts in binary fission whereas a single entity divides into many parts in multiple fission. Fission is a method of asexual reproduction shown by Bacteria, Archaea and some other single cell organisms. It is the process of dividing […]

The key difference between bacterial endospores and fungal spores is the cellular organization of the two types of spores. Bacterial endospores are dormant structures present in prokaryotic bacteria. Fungal spores are reproductive structures present in eukaryotic fungi. Bacterial endospores are present within the bacterial cells, and they are dormant structures that can survive the harsh environment […]
