Introduction:
Microbes have an essential role in all forms of living species on earth. So, it is considered one of the vital things for plants, animals, and humans. The science also claims that microbes significantly impact food production and nutrition. One such traditional technology is fermentation which has been used for food production, and it has the properties of enhanced nutritional value, improved microbial safety, and prolonged stability. Recently, there claims the pivotal role of microbes in overall health and human development.
What Is the Role of Microbes in Nutrients?
Microbes are found in the various parts of living organisms. Consequently, microbes are keen on maintaining a healthy environment (microbiome) in the gut. So, in this way, the clinical research says that certain microbes protect against cancer or reduce several cancer risks through their role in gut microbiota, suppressing cancer associated with inflammation and DNA damage. They can also directly influence or limit tumor growth.
What Are the Microbes That Help With Human Health?
Gut microbiota, also called gut microbiome or gut flora, are the microbes such as bacteria, fungi, viruses, and archaea that sustain in the digestive tract of humans and animals. The gut is considered the predominant site of the human microbiome, whereas the human microbiome refers to the aggregate of microbes residing in the human system.
Certain cancer-protective microbes, including Lactobacillus gasseri, Lactobacillus pentoses, and Bifidobacterium bifidum, are still found in specific food sources and environments. The best part is these microbes can live in the gut maintaining a gut microbiome. Such microbes significantly strengthen cell cooperation and limit cheating cells by enhancing the body’s defense mechanism. Other cancer-inducing microbes can promote cancer and are considered harmful as they release toxins for cancer induction and progression. Such microbes include Helicobacter pylori, Papillomavirus, and Enterococcus faecalis. So not every microbe is essential for human living.
What Is a Diet That Incorporates Healthy Microbes?
The microbes we consume become essential to a healthy and nutritious diet. Also, the microbes we include in the diet can alter or modify the gut microbiome. The type of microbes either enhance a good human microbiome or cause certain GI concerns. Our nutritious diet also determines the quantity of cancer-inducing or cancer-preventing microbes in the body. The beneficial or healthy microbes are mainly found in plant-based and fermented foods. Such foods have a significantly high nutritional value, and those microbes have a role in increasing the ability of the immune system and diminishing inflammation. The high-fiber foods are said to be prebiotic, which means they provide resources for those healthy microbes to thrive and also benefit the hosts.
The beneficial microbes are seen in the following food sources and items.
-
Vegetables.
-
Fruits.
-
Greens.
-
Yogurt.
-
Kefir.
-
Kimchi.
-
Whole grains.
-
Legumes.
-
Fermented probiotic milk.
-
Lactic acid bacteria fermented cabbage.
-
Fermented soybean.
-
Another fermented foodstuff.
Conversely, harmful or unhealthy microbes are seen in highly-processed and meat-containing diets. So, the modern diet is known to have a more significant amount of red and processed meat, processed foods, fried items, and high-sugar foods. Clinical findings show that meat-based diets can incorporate cancer-inducing microbes like Peptostreptococcus and Fusobacterium.
What Is the Role of Nutrients for Microbes?
Nutrients also have a role in the microbe's survival and growth, just like microbes have a significant role in nutrition. Microbial cells take up various functions, including growth and metabolic process. So, they require energy sources for these functions that nutrients can obtain.
Nutrition Required by Microbes:
Microorganisms need about ten elements since they are used to build lipids, proteins, carbohydrates, and nucleic acids. They also require several other elements in lesser quantities.
The microorganism requires the following common macro elements and electron sources for nutrition.
-
Electron Sources: They can be used for other cellular works.
-
Carbon, Oxygen, and Hydrogen Molecules: They are the components of organic molecules.
-
Sulfur: Sulfur is considered essential for amino acid biosynthesis.
-
Nitrogen: It is also involved in amino acid biosynthesis.
-
Phosphorus: It is found in nucleic acids and phospholipids.
What Are the Nutrition Sources for Microorganisms?
The sources of nutrition for microbes include light, heat, and other plant sources. Moreover, Microbial cells demand other essential nutrient compounds for their growth and replication.
They are listed as follows.
1. Microbial cells require major elements or macronutrients like carbon, oxygen, nitrogen, sulfur, phosphorus, hydrogen, potassium, calcium, iron, and manganese. These are required in larger quantities and as components of synthesizing carbohydrates, lipids, proteins, and nucleic acids.
2. Microorganisms also require several micronutrients or microelements. They include manganese, cobalt, nickel, zinc, and copper. These elements have significant roles in the cells involving the enzymes and cofactors inducing catalytic reactions and maintaining protein structure.
3. Growth factors are the other nutrients for microbes. They are organic compounds that are required as essential cell components. There prevail three predominant classes of growth factors.
The potential growth factors that the microorganism relies on are the following.
-
Amino acids are essential for protein synthesis.
-
Vitamins are the organic molecules that complete all or a part of the enzyme cofactor. Nevertheless, only a tiny portion of vitamins is required to grow microbes.
-
Purines and pyrimidines for the synthesis of nucleic acids.
The other enzymes and cofactors needed in very smaller amounts for the sustenance of attained growth and function include folic acid, biotin, vitamins B12, and vitamin K.
Conclusion:
Microbes and nutrition have related in two ways either. The microbes are present in the gut to maintain a healthy environment intending to prevent several conditions. So, microbes have a role in nutrition, and the associated food items can be taken to enhance the gut microbiota. So, one can go with high-fiber foods called prebiotic ones and a diet containing fruits, vegetables, greens, and other plant-based sources. In another way, the microbes require nutrients for their growth, survival, and replication. The microorganisms take up the nutrients primarily for their energy source.
