You may have heard a lot about probiotics, effective microorganisms (EM), microbial preparations, etc. Today, let’s dive into probiotics with BSF Smart Farm. It only takes you a 5-min read to get the full picture.

Probiotics – Effective Microorganisms

Let’s explore these two product lines.

What are probiotics?

Based on the results of empirical studies, probiotics shall be prepared and extracted from materials found in nature. They can be derived from plants (algae, moss, etc.), animals (composting earthworm – Perionyx excavatus, insects, etc.), and microorganisms. Probiotics are environmentally friendly, safe for humans, animals, plants, and suitable for waste treatment.

Probiotic is derived from the Greek word “pro” meaning “for”, and “biosis” meaning “life”, and means “for life”. Probiotics are beneficial bacteria that can be used as dietary supplements.

What is EM?

EM is a natural probiotic produced by Effective Microbiological Technology – a modern, multi-purpose and safe biotechnology solution developed by Japanese scientists. EM is the abbreviation of Effective Microorganisms, a group of coexisting naturally-occurring beneficial microorganisms.


EM1 is the original EM solution. It comes in liquid form and contains different groups of microorganisms. EM1 can be used as is or used to prepare EM2.


EM2 is a secondary probiotic. Adding molasses and clean water into EM1, and leaving the mixture still for a particular amount of time shall produce EM2.

Common strains of probiotic organisms

  • Group 1: Living microorganisms such as Bacillus, Lactobacillus, etc. They are often used as feed additives to increase digestion and ensure faster growth.
  • Group 2: Antagonistic microorganisms such as Bacillus They are used to treat organic waste and harmful gases in the pond.
  • Group 3: Microorganisms improve environmental quality such as Nitrosomonas, Nitrobacter, etc. They are used to treat water in the pond and pond bottom.

Trichoderma-based probiotics:

Trichoderma-based probiotics contain primarily Trichoderma – a genus of fungi, and hydrolytic enzymes such as cellulase, chitinase, xylanase, hemicellulose. It is effective in enhancing plant resistance to disease.

Bacillus-based probiotics:

Bacillus-based probiotics contain primarily two microbial groups: Trichoderma sp and Bacillus sp group. Both groups exhibit robust abilities in degrading cellulose, and producing bioactive compounds that antagonize and destroy pathogens.

Amino-based product:

Sulfur-containing amino acids are vital in plant defense against pests and diseases. They also act as phytohormones by reducing fruit drop.

Common traits between groups of microorganisms

  1. Lactobacillus is a group of facultative anaerobic bacteria that ferments food carbohydrates and produces lactic acid as the main product. Lactobacillus can be used as probiotics in raw feed production and larval rearing. Lactobacillus is sensitive to high temperatures.

  1. Bacillus is a group of anaerobic bacteria. When used as probiotics, Bacillus maintains the pond’s oxygen demand and can be mixed into feed and processed into pellets. Bacillus has high-level heat resistance.
  2. Nitrobacter and Nitrosomonas are called Nitrifying bacteria, a group of aerobic bacteria that convert NH3 to a less toxic byproduct NO3-, a process called nitrification. As nitrification requires a large amount of oxygen, it is essential to provide enough oxygen to the pond in order to ensure animal’s health and increase the effectiveness of the probiotic activity.
  3. Non-pathogenic Vibrio species: the genus Vibrio has a wide range of species. While some of them are beneficial to the environment and harmless to livestock, some are found pathogenic to aquatic animals. Probiotics containing non-pathogenic Vibrio species can be used to outnumber pathogenic Vibrio species, limiting or eliminating their presence in the pond.
  4. Yeast can bind to and grow well on the intestinal cells, and withstand high temperatures in pelleting technology. That is why, probiotic yeast can be mixed with feed for animals.

Modes of action of probiotics

  • Competitive exclusion of pathogens: By adhering to the intestinal mucosa, probiotics serve as a defense mechanism against pathogens through competition for adhesion sites and organic substrates.
  • Inhibitory activity: Recent studies have shown that probiotics can produce substances with bactericidal properties that can prevent common pathogens in animals.
  • Immune modulation: Probiotics can act as a stimulus for the immune system. Probiotics used with such a purpose vary depending on environment and usage.
  • Certain derivatives (i.e. polysaccharides, lipoproteins) can induce macrophage activation, leading to an increase in the number of white blood cells. Bacillus has been proven effective in animal disease prevention by stimulating the immune system, even cellular barriers in giant tiger shrimp.

What are benefits of probiotics?

Enhancing disease resistance:

  • Probiotics contain antagonistic microorganisms that inhibit and prevent pathogens in plants and animals.
  • Probiotics contain friendly bacteria that compete with pathogens for adherence sites and food in the intestinal walls, thus preventing colonization by pathogens. This trait of probiotics helps animals improve health and resistance to disease.
  • Probiotics are effective in preventing pathogens and controlling diseases in livestock and aquaculture, thus reducing antibiotic use.

Improving the digestive system:

  • Probiotics synthesize essential nutrients (vitamins, fatty acids, amino acids,…) and extracellular enzymes (proteases, amylases, lipases,…) that help enhance animals’ digestive tract.
  • In fish, microorganisms like Bacteroides and Clostridium contribute to the host’s nutrition, especially by supplying fatty acids and vitamins.
  • In addition, certain bacteria also support the digestion of bivalve species by producing extracellular enzymes (proteases, amylases, lipases,…) and essential nutrients (vitamins, fatty acids, amino acids,…)

Potential uses of probiotics?

Probiotics are widely accepted and adopted in crop and livestock agriculture. Let’s take a look at their specific benefits.

Probiotics for aquaculture

In water

  1. By decomposing organic matter or oxidizing toxic substances by harmful bacteria into harmless ones, beneficial bacteria help improve water quality and clean pond bottom.
  2. Beneficial bacteria lead the competition for living space and shut out pathogens. Pathogenic bacteria or bacteria involved in the decomposition of organic matter to toxic products (NH3, NO2, H2S) are grouped as harmful bacteria.

In guts of shrimps, fish

In the host gut, beneficial bacteria also compete with harmful bacteria that cause gut diseases. Furthermore, several studies have revealed the involvement of beneficial bacteria in many metabolic pathways, helping to produce vitamins and increase nutrition intake.


  • Clean pond bottom and reduce black mud.
  • Eliminate harmful gases in the pond (ammonia, hydrogen sulfide, nitrogen dioxide, etc.)
  • Increase oxygen content in the bottom, and create a natural antibacterial environment in the pond.
  • Keep water clean, stabilize PH, balance the ecosystem.

Probiotics for plants

Advantages associated with the use of probiotics in agricultural production

  • Having no negative effect on human health, animals, or plants, causing no harm to the environment
  • Maintaining a balanced ecosystem (microorganisms, nutrients, etc.) in the soil and the environment as a whole.
  • Being a friendly substance to soil texture, causing no soil compaction and degradation, and increasing soil fertility.
  • Contributing to the anabolism process, thereby enhancing productivity and quality of agricultural products.
  • Eliminating harmful insects, fighting against diseases, and increasing plant resistance while causing no adverse effect on the environment like other chemical-derived crop protection products.
  • Breaking down persistent organic substances, biological wastes, agricultural and industrial wastes, contributing to environmental cleaning.

Probiotics for plants are divided into 3 groups with different features:

  • Probiotics for pest and disease control.
  • Probiotics for the production of bio-organic fertilizers, microbial fertilizers, and crop stimulants.
  • Probiotics for soil improvement and agricultural waste treatment.

Probiotics as feed additives

Probiotic feed additives are probiotics used to ferment animal feed and help colonize the gut of livestock and poultry with good microbes.

Starch (such as bran, cornstarch, tapioca,…) makes up 80% of animal diet. If left uncooked, starch might cause digestive problems, leading to ineffective animal farming and high cost. Animals (livestock, poultry, aquatic animals,…) shall digest and absorb feed more efficiently if being fed with cooked feed.

A method of cooking – fermentation – has been used since ancient times, thanks to a kind of microbial enzyme available in nature.
