When considering different types of algae, you’ll find they are split into two categories: macroalgae and microalgae. Microalgae have a single cell, and the most common forms of this type of algae are chlorella and spirulina. They are all found in marine and freshwater environments, and you’ll often find these algae are sold for human and animal consumption. Here we’re going to take a look at what is microalgae used for and the production and benefits of this type of algae.

Microalgae Characteristics
The microalgae definition states that they consist of a single cell structure, and for this type of algae to grow, it requires water, light, carbon dioxide, and nutrients. Microalgae then use photosynthesis to convert these substances for their cell development. Lipids, carbohydrates, and proteins make up microalgae, and different amounts of each of these are stored within its cell. Microalgae characteristics include that they are very adaptable. Which means they can grow in a wide variety of environments as they don’t rely on land in the way other plants do. Some species are even able to adapt to changes in conditions as they alter their chemical composition in response to their environment. When looking at what can algae be used for, it’s a food source for animals and humans and is an excellent option as the growth rate is five to ten times quicker than other common food harvests.
Types of microalgae
The most common types of microalgae that are grown and sold throughout the world today are spirulina and chlorella. Here we’re going to look at these types of microalgae and what is spirulina and chlorella good for.
Spirulina
For anyone wondering what are microalgae, you’ve probably heard of spirulina. Spirulina is a blue-green algae, and it can be grown in either freshwater or saltwater. It consists of a single cell and forms a spiral or helix as they join together. It’s rich in protein, vitamins, and minerals, which is why it’s often used as a supplement by humans today. Spirulina is packed with antioxidants and anti-inflammatory properties and is considered a superfood. It is often added to smoothies or recipes by individuals. It generally needs to grow in alkaline water, and it can be very difficult for the human eye to see spirulina, as it’s generally between 0.3 – 0.5 mm in size.
Chlorella
Similarly, you may be wondering what is chlorella vulgaris, which is another commonly consumed microalgae. Chlorella is another type of microalgae, which is a green algae that also contains just a single cell. There are roughly thirteen types of chlorella, and it’s also known for its benefits to humans and animals who consume it. Reasons for humans consuming this type of microalgae are to reduce blood sugar levels or cholesterol levels. It is believed to date back over two billion years, making it one of the oldest living beings on our planet. Chlorella is grown in freshwater pools and relies on natural sunlight to create its cells. It will thrive when it grows in nutrient-rich water, and some variants can also grow in soil. It’s grown using photosynthesis, and its high protein levels make it a good option for both human and animal feed.
Of course, these are just two of the most commonly known and used type of microalgae. Other options include Dunaliella salina, Chlamydomonas reinhardtii, and Spirogyra, which are all rich in protein but are less commonly used and consumed. For anyone questioning what is dunaliella salina, it’s a green microalgae that is high in antioxidants. You may have heard it mentioned before as it’s commonly found in dietary supplements and even cosmetics.
Production
Microalgae production occurs in a few different ways. Heterotrophic cultures use glucose or another organic carbon as a source of energy and carbon to grow microalgae. Phototrophic cultures use light with carbon dioxide, and mixotrophic cultures are a combination of the two, which result in a higher cell production rate. They are generally grown in marine and freshwater environments and are very adaptable to their environment. After they are grown, microalgae are harvested, and their water levels are reduced at this point. Bulk harvesting and thickening obtain the solid matter that is used for human and animal consumption. Food sources such as spirulina are grown in labs for nutritional reasons, and only a single cell is needed to begin this process. It’s then processed into supplements or powder form to be consumed.
Microalgae benefits
Microalgae, such as spirulina and chlorella, have become increasingly popular in recent years. They are used for animal and human consumption, primarily due to the microalgae health benefits. Spirulina is rich in nutrients and has been consumed by humans for hundreds of years. Even just the small recommended daily serving offers high levels of protein, thiamine, niacin, riboflavin, copper, and iron. It offers consumers anti-inflammatory and antioxidant properties, which can reduce inflammation in your body. Inflammation is something we should avoid, as it may result in cancer or other diseases in the long run. Due to the presence of phycocyanin in spirulina, it fights against free radicals and reduces inflammation when taken regularly.
Chlorella also offers similar benefits to consumers. It’s packed with nutritional benefits and is rich in protein. It offers all the essential amino acids and is also a good source of iron and vitamin C. Similar to spirulina, it’s a good source of antioxidants, and when eaten in larger amounts, you’ll find it offers plenty of fiber to consumers as well. Chlorella has become increasingly popular due to its detoxifying benefits, as it can bind to any heavy metals in the body.
Is spirulina good for dogs?
More pet owners are looking at alternative feed solutions for their dogs today. Algae proteins are becoming increasingly popular alternatives to standard pet food. We understand that you may have concerns and wonder: is spirulina good for dogs? Spirulina pet food is generally considered safe for dogs to consume, however, you’ll want to be very careful about where you are sourcing this ingredient from. Cheap or fake spirulina products may cause more harm than good, so you want to ensure you are offering your dog the highest quality spirulina. If you are wondering what are the benefits of spirulina for dogs, you’ll be impressed by what it can offer your pet.
When consumed in a pure form, it’s packed with protein, chlorophyll, and offers many key vitamins and minerals to dogs. Dogs will also receive omega-3 fatty acids, so it’s well worth adding to your dog’s diet. Spirulina can help to minimize inflammation and potentially will reduce the chance of cancer occurring. It’s also believed to boost a dog’s immune system and combat bacteria and yeast growth in their body.
There are so many benefits of consuming microalgae. Which is why spirulina and chlorella have become so popular with humans in recent years. Always ensure that any microalgae you or your pet consumes are of good quality to avoid any side effects or issues when using this source of protein for the first time.
