ARTICLE 62 FEED & ADDITIVE MAGAZINE July 2022 SINGLE CELL PROTEIN: THE POTENTIAL SUBSTITUTE OF ANIMAL NUTRITION “Single cell protein (SCP) shows very attractive features as a nutrient supplement for animals. It basically comprises of protein, carbohydrate, fats, water and elements like phosphorous and potassium and essential amino acids. SCP has various benefits over animal and plant proteins in that its requirement for growth are neither seasonal nor climatic dependent therefore it can be produced allround the year. It can be grown on waste and is therefore environment friendly.” The world population is continuously increasing with increasing rate. By 2050, the world population could increase to 9.4 billion which at current consumption levels would cause the global demand for animal-derivative protein to reach 1250 million tons per year. According to some studies, the population increase will also be accompanied by economic progress, and due to which the increase in the living standard of about 3 billion people that subsequently increase the demands of food and water as well as there will be increasing demand of good quality food. Globally the problem of malnutrition is increasing rapidly in developing countries as the population is increasing with an upright pyramid, which shows the increasing population of young and those required good quality of food. The competition for the good quality food with human, the animals also suffer a lot as the high yielders also require good quality of protein to produce good quality products. As the population of humans is increasing, the load on production of good quality food to meet the demand also increases and this puts a burden on the environment and also on the economy. The limited land is the problem and production is affected by several reasons. Therefore, the production of single cell proteins is promising way to tackle protein deficiency problem worldwide. Single cell proteins (SCPs) or microbial proteins are the dead dried cells of microorganisms or purified protein isolated from microorganism’s cell culture and used in animals feed as fattening poultry, calves, pigs, and fish. It also has applications in leather and paper industry. SCPs have nearly 60 to 80% protein content in them on dry matter basis. SPCs contain high quantity of essential amino acid like methionine and lysine. Conventional substrates like starch, fruit, molasses and fruit waste and unconventional substrates like petroleum by products, ethanol, natural gas, lignocellulosic biomass and methanol have been used for SCPs production.
