What is cyanophage with example?
Cyanophages are viruses that infect cyanobacteria, also known as Cyanophyta or blue-green algae. Cyanobacteria are a phylum of bacteria that obtain their energy through the process of photosynthesis.
Who discovered cyanophage?
Cyanophages were first discovered by Safferman and Morris (1963) from a waste stabilization pond of Indiana University (USA). The first cyanophage studied by Safferman and Morris was the cyanophage attacking Lyngbya, Plectonema and Phormidium. They named the virus as LPP-1 using the first letter of the three genera.
What are Actinophages?
Filters. Any bacteriophage that infects bacteria of the order Actinomycetales. noun. 1.
What are bacteriophages made of?
All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell.
Which of the following is a Cyanophage?
LPP-1 was the first cyanophage, which was discovered by Safferman and Morris. It was so named because it can infect three different blue- green algae, which are Lyngbya, Pnormidium and Plectonema.
What kind of organism are algae?
photosynthetic organisms
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.
Can bacteriophages infect human cells?
Phages cannot infect human cells, and so they pose no threat to us. Figure 2 – Bacteriophages have protein heads and tails, which are packed with DNA. When a phage attacks a bacterium, it injects its DNA. The bacterium them makes more phages that are released when the bacterium bursts.
Who is discovered virus?
In 1892, Dmitri Ivanovsky used one of these filters to show that sap from a diseased tobacco plant remained infectious to healthy tobacco plants despite having been filtered. Martinus Beijerinck called the filtered, infectious substance a “virus” and this discovery is considered to be the beginning of virology.
How do algae photosynthesize?
As a general rule, algae are capable of photosynthesis and produce their own nourishment by using light energy from the sun and carbon dioxide in order to generate carbohydrates and oxygen.
What is algae made from?
Algae is composed of ~ 50% carbon, 10% nitrogen, and 2% phosphorus. Table 10.3 shows the composition of various algae looking at the percentages of protein, carbohydrates, lipids, and nucleic acid. Table 10.3: Composition of algae – protein, carbohydrates, lipids, and nucleic acid. Spirogyra sp.
What is the cycle of bacteriophage?
The lytic cycle, which is also referred to as the “reproductive cycle” of the bacteriophage, is a six-stage cycle. The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.
