Algal cultivation means growing algae (microalgae or seaweeds) in controlled or partly controlled environments for useful biomass. The algae are supplied with light, carbon (often CO₂), water and nutrients so growth is promoted. In open ponds (raceway ponds etc.), cultures are exposed to ambient conditions, and mixing is provided to avoid shading and settling. Photobioreactors … Read more
Economic Importance of Algae Overview Algae is a photosynthetic, eukaryotic marine organism. Their size ranges from unicellular microalgae to giant kelp. Algae are characterized by their lack of flowers, formal roots, leaves, or even stems. They can grow anywhere such as in the dirt or on rocks, marine water, freshwater, etc. Algae are variable in shapes, … Read more
The reproduction in Algae is considered to be a fundamental biological process, and it is carried out by different modes which are usually classified into Vegetative, Asexual, and Sexual methods. By vegetative processes, new individuals are produced from somatic parts, and this happens without involvement of spores or gametes, which makes it simple yet very … Read more
Algal morphology is defined as the study of body structure and organization of algal cells and their thalli. Algae are observed in a diversity of sizes and shapes, from microscopic single-celled forms to large seaweeds several meters long. The science concerned with algae is termed Phycology, and a specialist is called an Algologist or Phycologist. … Read more
What is Euglena? The term Euglena denotes a genus of unicellular, flagellated eukaryotic organisms (protists). In many habitats (freshwater, moist soils, brackish waters) these organisms are found. The cell is bounded by a flexible proteinaceous pellicle (not a rigid cell wall), which allows shape changes (metaboly) under movement pressures. One or two flagella (one often … Read more
What is Algae? Characteristics of Algae Habitat of Algae The Habitat of algae is described as highly diverse, because algae are of universal occurrence and are found in water, land, snow, hot springs, inside plants/animals, and even in extreme saline or aerial conditions. The Aquatic algae are predominant in occurrence, and they are present in … Read more
Polymerase chain reaction or PCR is a laboratory technique that is used to make multiple copies (millions or billions!) of a specific region of DNA in vitro (in a test tube rather than an organism).
What is Reverse Transcription PCR (RT-PCR)? Reverse Transcription Polymerase Chain Reaction (RT-PCR) is defined as a lab method in which RNA is converted into complementary DNA (cDNA) by an enzyme called reverse transcriptase, then that cDNA is amplified via PCR. The technique is used for detection, quantification of specific RNA molecules (eg mRNA, viral RNA) … Read more
A real-time polymerase chain reaction (real-time PCR) is a conventional polymerase chain reaction (PCR) based laboratory technique used in molecular biology for real-time monitoring of the amplification of a targeted DNA molecule during the PCR, not at its end, as the conventional PCR do.
What is Repetitive sequence-based PCR (rep-PCR)? Working Principle of rep-PCR The rep-PCR working principle is based on the occurrence of conserved repetitive DNA elements (REP, ERIC, BOX, GTG5 etc.), which are dispersed at multiple sites within prokaryotic genomes, and these elements serve as priming sites for amplification. By the use of specifically designed primers, annealing … Read more
