Later, I discovered that these questions are available on Google Question Hub, along with many other unanswered questions.

You will find 3 descriptive and useful pieces of content about spirulina on Edumeduawellness that I've published earlier. The purpose of creating this content is to provide the queries-specific information to the users. 

The relevant content published earlier on this site about spirulina are-

How to Cultivate Spirulina in Your Area

In this fresh content, I will answer those queries not yet covered earlier. I am going to start with the' ideas panel' of Edumediawellnes's site.

The average yield of Spirulina from one square meter

That means users want to know the yield of spirulina per square meter (ignoring the depth of the Tank). Well, Let me proceed.

If you maintain an ideal depth of your tank, then expect the yield of 10 grams per square meter/ day. But any change in depth will give different results.

Yet, you can increase the production rate up to 20 grams per day/per square meter by optimizing the temperature, intensity of lighting, production system, and other conditions.

In fact, the yield of spirulina/Arthrospira Platensis depends upon many factors such as climatic conditions, temperature fluctuation, availability of sunlight, types of water used, water levels in your tank, and more.

According to Grow-organic-spirulina, the yield of spirulina depends upon the length, width, and depth of the pool. So instead of a square meter, you should measure the production rate per cubic meter/time period.

As per their opinion, 6 to 15 gm per cubic meter/day is the expected yield that depends upon the conditions of harvesting. 

Water content in the pool can be found out by applying the formula:

Length (meter) x width (mtr) x depth (cms) x1000.
You can use their Free Harvesting Calculculator provided on the site.

Is the climate of Bilaspur Himachal Pradesh is suitable for the cultivation of spirulina?  

Ans. Please read the climatic conditions discussed in the next paragraph (passage).

How to identify and make sure that the growing zone is Spirulina or not?

Please read the next paragraph (passage) [ Ideal Climatic Conditions].

Ideal Climatic conditions for the cultivation of spirulina

Tropical and sub-tropical regions are ideal for the cultivation of spirulina. Temperature and light are other important conditions for spirulina culture.

Ideal Temperature for spirulina cultivation:

To get the maximum yield, a temperature between 30° to 35° C is ideal. Spirulina can still grow at 22° on the lower side and 38° C temperature on the higher side. But its protein content and color will be affected badly. Spirulina will die below 20° C and above 40°.

The intensity of light :

The intensity of light is an important growth factor of spirulina. Adequate light is essential for spirulina to grow. As it is a photosynthetic organism, light plays a significant role. It needs adequate light to grow well as a photosynthesizing organism.

Light has a direct impact on the protein content of the algae, growth rate, and the pigment synthesis of spirulina. The intensity of light between 20 to 30 K lux is considered ideal for Spirulina farming.

Wind, rainfall,  and solar radiation are also to be considered for the cultivation of it.

To check the average weather of Bilaspur of Himachal or any other zone use Weatherspark.

 Is spirulina useful for the experiment of photosynthesis?

Yes, Spirulina is useful for the experiment of photosynthesis.  The blue-colored phycocyanin pigment helps photosynthesis. These bacteria also contain chlorophyll and carotenoids. 

We know that for photosynthesis, the presence of chlorophyll is essential. Other requirements for photosynthesis are sunlight and water. Thus, Spirulina is photosynthetic and is useful for photosynthesis experiments.

Spirulina as a feed additive to fishes

In this section, I'll discuss three topics- the benefits of Spirulina as a feed additive to fishes, Tokyo (Tokyu) Spirulina food, the quantity of spirulina needed per ton of fish to feed.

What are the benefits of Spirulina as a feed additive to fishes?

It enhances the color of fishes, reduces medication, boosts immunity, and improves reproductive performance. Spirulina also reduces drug toxicity and reduce the dependency of antibiotic.

Fish farmers have experienced that feeding spirulina to sick fish has reduced the amount of medication or treatment needed to treat it.

Spirulina feeding can reduce the need for a “water bath” treatment of fish. It ensures a uniform growth rate. It helps improve the digestive system of fish. The benefits of spirulina are almost similar to humans and fishes.

Which type of fishes eats Tokyo (Tokyu) Spirulina food?

Tokyu spirulina food contains sticky protein and floating in nature. So they never cloud the water. Tokyu spirulina supplement food is a favorite for tropical fish.

How much quantity spirulina per one-ton fish feed?

The quantity of spirulina required to feed the fishes depends upon the age, size, spices, and number of fishes.

Is the layer structurally similar in both spirulina and spirogyra cells?

 A comparison between the structure of Spirogyra and Spirulina is needed for the answer to this question. Let me start with the structure of Spirogyra, commonly known as pond silk or water silk.


Spirogyra/Water silk green algae

Spirogyra or water silk is a genus of filamentous green algae grown in freshwater. Its characteristic is the spiral arrangement of the chloroplasts in its cells. 

You will find this unique feature of this genus of around 400 species worldwide. Hence the name is derived from the spiral arrangement of chloroplasts in this algae.

Spirogyra contains a cell wall, nucleus, pyrenoid, and spiral chloroplasts. Spirogyra is said to be filamentous algae since it has long filaments [10-100 micrometer] with cylindrical cells connected.

The cell wall has two layers, the outer layer is made up of pectin and the inner layer is cellulose. The inner surface of the cell wall is marked with a soft thin layer of cytoplasm.

The spiraled ribbon-shaped chloroplasts [1 - 16 in numbers] are embedded in the cytoplasm.

The rounded bodies of each chloroplast are named Pyrenoids to help for starch production.

Each cell contains a nucleus connected to the inner part of the cell wall.

Spirulina is a kind of spiral-shaped bacteria the blue-green algae. Spirulina grows in freshwater as well as saltwater. It is known as a superfood rich in protein, vitamins, minerals, and many antioxidants. It is a consumable bacteria for humans and animals specifically for aqua animals.

Now, let me give an overview of the spirulina cell structure. The Spirulina cell wall is made up of four layers- LI, LII, LIII, and LIV.

The innermost layer is LI and the outermost is LIV. LII made up of peptidoglycan, a substance that gives the wall its rigidity. All other layers are weak compared to LII.

The LI layer contains b-1, 2-glucan, and a polysaccharide.

This layer is easy to digest for the low concentration (<1%) and thickness (12 mm)

The location of chlorophyll, carotenes, and phycocyanin (blue pigment), is in the thylakoid.

The inter-thylakoid space contains protein gas vesicles in cylindrical form, which provides it the floating function.

So, despite some similarities, differences also exist between the layer of the two.

 Whether Spirulina have chlorophyll

Chlorophyll is the green pigment found in the chloroplasts of algae and plants.
 Yes, chlorophyll is present in spirulina that I've mentioned in the previous paragraph.

Spirulina culture

Spirulina culture is a fluid containing the live organism of spirulina. The growth rate of Spirulina culture is 25% each day in an ideal condition. 

What are the testing parameters for spirulina quality?

Phycocyanin is the prime ingredient. Any spirulina containing less than 10 percent phycocyanin is of poor quality. Apart from photosynthetic pigment, phycocyanin is an effective antioxidant. 

Phycocyanin provides a significant amount of protein. High-quality spirulina contains a higher percentage of it. 15%-20% is considered good quality.

When some company offers spirulina at a cheap price, please check the Phycocyanin content of it as this blue pigment provides you many health benefits.  

Many spirulina farms extract this blue pigment to sell in the food industry. This blue pigment is used mainly as a natural coloring in the food industry.

Asian Journal of Green Chemistry has described the process of extraction of  Phycocyanin from Spirulina Platensis.

How much tryptophan occurs in 500 mg spirulina?

 Tryptophan is an essential amino acid that your body needs for many reasons. Usually, 100-gram Dried spirulina contains 929 mg.

So in 500 mg dried spirulina, you will get 4.645 mg tryptophan. But it depends upon the moisture content and quality of it.

Spirulina chikki product information and usefulness

Chikki is a popular food in India and some Asian countries. Groundnut, sesame, peanut, and jaggery are used as ingredients to prepare chikki. When spirulina is used as an ingredient of chikki it is called spirulina chikki.

 As spirulina is loaded with protein, vitamins, and many other micronutrients, spirulina chikki is better than other kinds of it.

Are spirulina supplements safe? 

Health Consultants usually consider Spirulina to be safe because of its long history as a food. 

If  Spirulina grows in unsafe conditions, it may become contaminated with toxic metals and poisonous bacteria.

Polluted Spirulina can cause nausea, vomiting, thirst, weakness, and many other complicated diseases. Investigating the source of Spirulina supplements is essential to ensure quality and safety. 

How to use and Dosage

Pregnant or breastfeeding women should avoid Spirulina. Women during the menstruation period should also avoid it as inadequate studies and research are there to establish it is safe to use during those periods. 

The doses of spirulina supplements may differ from company to company. The manufacturers generally mention the doses on the package. Follow the instruction of the company. 

General instruction is to take spirulina supplements (tablets, capsules, and powder) with water before a meal. It is best to consult a doctor/nutritional expert before use to avoid an overdose.

According to the National Institutes of Health (NIH ) U.S. National Library of Medicine, the evidence to rate the effectiveness of many diseases is insufficient. Therefore adequate evidence of the blue-green algae for those uses is needed to confirm the effectiveness.

Special precautions to be taken as per the recommendation of NIH in the following circumstances- 
  • Pregnancy and breastfeeding women
  • Children
  • Autoimmune diseases 
  • Bleeding disorders
  • Diabetes
  • Phenylketonuria
  • Surgery
In any of the above circumstances, avoiding the use of spirulina is the best decision.

Spirulina supplement manufacturing and selling companies

Many companies engaged in the marketing of spirulina belong to direct selling (network marketing or MLM). Some companies have their own manufacturing facilities. Buying from the manufacturers is more reliable than from the traders.

Spirulina and Kovid-19

Don't consider it as a medicine for recovery of coronavirus attack or as a vaccine to prevent coronavirus. During Kovid-19, apart from maintaining cleanliness, mask, and social distance, taking healthy food is essential for you to lead a healthy life.

It is an undeniable fact that spirulina is a healthy food rich in protein, vitamins, minerals, antioxidants, and more. Besides, it will act as an immunity booster. You need both physical and mental strength during this period.

Reading  Inspirational Health Quotes may increase mental strength.

Where to sell spirulina/ How to do marketing

For selling the spirulina, register as a seller with the e-commerce companies like Amazon, Flipkart, eBay, and so on. The second option is to contact the local spirulina firms having less production capacity compared to the demand.

If you thinking of a large scale, then try marketing through  B2B marketing agents such as 

Is spirulina Halal

Most of the natural foods are halal. In Islam, unless specifically mentioned as Haram (prohibited) in Sariah, it is presumed to be Halal.
