Strain (biology)
In biology, a strain is a genetic variant, a subtype or a culture within a biological species. Strains are often seen as inherently artificial concepts, characterized by a specific intent for genetic isolation. This is most easily observed in microbiology where strains are derived from a single cell colony and are typically quarantined by the physical constraints of a Petri dish. Strains are also commonly referred to within virology, botany, and with rodents used in experimental studies. Microbiology and virology It has been said that "there is no universally accepted definition for the terms 'strain', ' variant', and 'isolate' in the virology community, and most virologists simply copy the usage of terms from others". A strain is a genetic variant or subtype of a microorganism such as a bacterial strain or a specific strain of a virus, or fungus. For example, a "flu strain" is a certain biological form of the influenza or "flu" virus. These flu strains are characterized ...

Polystyrene
Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. Polystyrene is naturally transparent to visible light, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and optical disc jewel cases), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records. As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled.

Shiv Nadar University
Shiv Nadar University (Institute of Eminence) is a private university located near Greater Noida, in the northern Indian state of Uttar Pradesh. It was founded in 2011 by Shiv Nadar, the founder and chairman of HCL. History The university, established in 2011 on a 286-acre campus, had Nikhil Sinha as its first Vice-Chancellor. On 1 February 2016, Rupamanjari Ghosh succeeded him as the second Vice-Chancellor. After completing her second term, she passed the leadership to Dr. Ananya Mukherjee on 31 January 2022. In May 2023, a student shot and killed another student before committing suicide. Reports indicated that the individuals had previously been engaged in a romantic relationship. In an investigation after an FIR was filed by the Uttar Pradesh police, it was revealed that following their breakup, the victim had expressed concerns to administrators regarding the shooter's behavior.

Bacillaceae
Bacillaceae, from Latin "bacillus", meaning "little staff, wand", are a family of gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. Motile members of this family are characterized by peritrichous flagella. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are not pathogenic, but ''Bacillus'' species are known to cause disease in humans. Gram-variable cell wall Some Bacillaceae, such as the genera '' Filobacillus, Lentibacillus,'' and '' Halobacillus'', stain Gram-negative or Gram-variable, but are known to have a Gram-positive cell wall.Lim, J.M., Jeon, C.O., Song, S.M., and C.J.

Plastivores
Mealworms, an example of a plastivore A plastivore is an organism capable of degrading and metabolising plastic. While plastic is normally thought of as non-biodegradable, a variety of bacteria, fungi, and insects have been found to degrade it. Definition Plastivores are "organisms that use plastic as their primary carbon and energy source". This does not necessarily mean being able to fulfill all biological needs from plastic alone. For example, mealworms fed only on plastic show very little weight gain, unlike mealworms fed on a normal diet of bran. This is due to plastic lacking water and nutrients needed to grow. Plastic-fed mealworms can still derive energy from their diet, so they do not lose weight like starved mealworms do. Mechanisms For both bacterial and fungal plastivores, the first step is adhesion of spores to the plastic surface via hydrophobic interactions. Bacterial plastivores, when cultured on plastic, form biofilms on the surface as the second step. Us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
