Summary
Microalgae offer a sustainable alternative to animal proteins, mitigating environmental impact and reducing risks of non-communicable diseases like inflammatory bowel disease (IBD) and non-alcoholic fatty liver disease (NAFLD). Their proteins and bioactive compounds show promise for promoting health.
Area of Science:
- Nutritional Science
- Environmental Science
- Biotechnology
Background:
- Animal-derived proteins pose environmental and health risks, including increased non-communicable diseases.
- Growing global population and protein demand necessitate sustainable alternative protein sources.
- Microalgae are recognized for high productivity, nutritional value, and environmental benefits.
Purpose of the Study:
- To review the potential of microalgae as a sustainable protein source.
- To explore the health-promoting applications of microalgae-derived proteins, peptides, and bioactive substances.
- To focus on microalgae's benefits for inflammatory bowel disease (IBD) and non-alcoholic fatty liver disease (NAFLD).
Main Methods:
- Literature review of studies on microalgal protein production and applications.
- Analysis of nutritional profiles and bioactive compounds in microalgae.
- Evaluation of health benefits, particularly for IBD and NAFLD.
Main Results:
- Microalgal biomass offers advantages in productivity, sustainability, and nutrition over conventional crops.

01:21Green Algae
62
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...

01:28Overview of Algae
62
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...

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...

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...

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
