L-form bacteria Definition “L-form” bacteria are also referred to as L-phase bacteria or L-phase variants, and cell wall deficient (CWD) bacteria are bacteria with no cell walls. They were first identified around 1935, by the scientist Emmy Klieneberger Nobel who identified them as “L-forms” after the Lister Institute in London which she was working at. … Read more

Bacteria constitute a vital element in the ecology. They are essential to our health as well as the environmental health, play an essential role in the production of food, and offer bioengineers the tools to harness their abilities and produce compounds. However, they could also be harmful, causing harm and diseases. The capacity to cultivate … Read more

What is Colony Morphology of Bacteria? Colony morphology of bacteria means the visible features seen in bacterial colonies when they grow on solid media like agar plates. Each colony usually comes from one bacterial cell that divides and forms a clump. These clumps or colonies can look very different based on the species and conditions, … Read more

What is Asexual Reproduction? There are animals that are born with two parents. Some animals can come from a single parent. For instance, the Komodo dragon, as an instance is the only one with one mother and reproduces through parthenogenesis.

Extremophiles Definition Importance in Research Classifications of Extremophiles There are numerous types of extremophiles found all over the world, and each corresponds to the manner in which its environmental niche differs from mesophilic circumstances. These categories are not exhaustive. Many extremophiles are characterised as polyextremophiles because they belong to many groups. Thermococcus barophilus, for instance, … Read more

Tetanus is caused by C. tetani, an obligate anaerobic Gram-positive bacillus.

Structure and Composition of Lipopolysaccharide (LPS) It is composed of three components like; O-antigen Core Structure of Core or Core oligosaccharide (or Core-OS) The core domain always contains an oligosaccharide component which attaches directly to lipid A and commonly contains sugars such as heptose and 3-deoxy-D-mannooctulosonic acid (also known as KDO or keto-deoxyoctulosonate). It is … Read more

What is Sphaeroplast? A Spheroplast (or sphaeroplast according to British use) can be described as a microbe organism with a cell wall that is almost entirely gone through the penicillin or Lysozyme. According to certain definitions the term is employed to refer to Gram-negative bacteria. In other definitions, the word also includes yeasts. Spheroplast’s name … Read more
