Overview of Algae01:28

Overview of Algae

The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...

Biofuels

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
Microbial Bioremediation of Hydrocarbons01:26

Microbial Bioremediation of Hydrocarbons

Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...
Preparation of Carboxylic Acids: Overview01:31

Preparation of Carboxylic Acids: Overview

There are various methods for the preparation of carboxylic acids. For example, oxidation of primary alcohols or aldehydes using strong oxidizing agents results in a carboxylic acid. Aldehydes can also be oxidized in the presence of mild oxidizing agents.
Green Algae01:21

Green Algae

Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
Other Algae01:19

Other Algae

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Phycology

Background:

  • Microalgal lipids are valuable commodities for biodiesel and omega-3 fatty acids.
  • Acetyl-CoA carboxylase (ACCase) is crucial for lipid synthesis, comprising biotin carboxylase, biotin carboxyl binding protein, and carboxyltransferase domains.
  • Information on ACCase in diverse algae is limited, despite its presence in chloroplasts and cytosol.

Purpose of the Study:

  • To investigate the types of ACCase present in algal plastids.
  • To determine if ACCase form (heteromeric or homomeric) correlates with plastid origin and symbiotic history.
  • To identify sequence differences for distinguishing ACCase types and localizations.

Main Methods:

  • Comparative analysis of ACCase amino acid sequences across various algal phyla.
  • Identification of conserved and variable regions within ACCase functional domains, particularly carboxyltransferases.
  • Bioinformatic approaches to predict ACCase localization (cytosolic vs. plastidial).

Main Results:

  • Green (Chlorophyta) and red (Rhodophyta) algae, with exceptions, possess heteromeric ACCase in primary plastids.
  • Algae with secondary plastids (Heterokontophyta, Haptophyta) and apicomplexan apicoplasts contain homomeric ACCase.
  • Distinctive amino acid differences were found in substrate binding regions of heteromeric/homomeric α-CT and β-CT, and in the acetyl-CoA binding region of homomeric α-CT.

Conclusions:

  • Plastid origin, determined by symbiotic events, dictates the form of ACCase in algae.
  • Sequence variations in ACCase domains provide reliable markers for differentiating heteromeric/homomeric and cytosolic/plastidial forms.
  • This research provides a foundation for understanding ACCase regulation and its influence on algal lipid production.
