Abstract

Single Cell Protein (PST) is the term used for proteins originating from microbes such as fungi, algae, yeast and bacteria. Tofu liquid waste is an alternative medium that has the easiest source of carbohydrates, so it has the potential for the growth of Saccharomyces cerevisiae. The aim of this research is to determine whether tofu liquid waste can produce single cell protein from S. cervisiae culture and to determine differences in protein production with the addition of nutrients to the fermentation medium. The research method used is experimental research. The independent variables are MFLT1 medium (Tofu Liquid Waste Fermentation Medium with the addition of KH2PO4 nutrients and sugar) and MFLT2 medium (Tofu Liquid Waste Fermentation Medium with the addition of KH2PO4 nutrients; (NH4)2SO4 and sugar); as well as fermentation time on days 0, 2, 4 and 6. The dependent variables are analysis of protein content, cell dry weight, glucose content, pH and temperature. The data from this research were analyzed statistically using the two way Anova method. The results of this research obtained the highest protein content in MFLT2 medium at 0.52% (day 2); cell dry weight 0.49 grams; glucose level 1.3345%; pH 5.0 and temperature 25.5 ⁰C. Meanwhile, in MFLT1 medium, the highest protein content was obtained at 0.35% (4th day); cell dry weight 0.363 grams; glucose level 1.3342%; pH 4.7 and temperature 28.8 ⁰C. From the research that has been carried out, it can be concluded that tofu liquid waste can produce single cell protein from S. cerevisiae cultures and there are differences in protein production results with the addition of nutrients to the medium, where the results of the protein content in the MFLT2 medium are higher than the protein content in the MFLT1 medium.

Abstract

Single Cell Protein (PST) is the term used for proteins derived from microbes such as fungi, yeasts and bacteria. One way to deal with the abundance of tofu liquid waste is by using microbiological methods, namely utilizing tofu liquid waste as a substrate for the growth of Bacillus cereus microbial growth for single cell protein production. The purpose of this study was to determine whether tofu liquid waste could produce single cell protein from B. cereus culture and to determine the difference in protein production by adding nutrients to the fermentation medium. The research method used was experimental research, with the independent variables being MFLT1 fermentation medium (Tofu Liquid Waste Fermentation Medium with the addition of KH2PO4 nutrients and sugar) and MFLT2 medium (Tofu Liquid Waste Fermentation Medium with the addition of nutrients KH2PO4; (NH4)2SO4 and sugar); and the length of fermentation on days 0, 2, 4 and 6. While the dependent variables were the analysis of protein content, cell dry weight, glucose content, pH and temperature. The result data in this study were statistically analyzed using the two way Anova method. The results of this study showed that the highest protein content was obtained in MFLT2 medium, namely 0.73% (day 4); cell dry weight 0.253 g; glucose level 1.3339%; pH 3.9 and temperature 29.2oC. Meanwhile, in MFLT1 medium, the highest protein content was 0.46% (4th day); cell dry weight 0.286 g; glucose level 1.3342%; pH 3.9 and temperature 28.8oC. From the research that has been carried out, it can be concluded that tofu liquid waste can produce single cell protein from B. cereus culture and there are differences in protein production results with the addition of nutrients, where the protein content in MFLT2 medium is higher than protein content in MFLT1 medium.

Abstract

Single cell protein is the term used for peoteins derived from microbes such as fungi. Pineapple waste is one of the alternative media that has easiest source of carbohydrates to obtain, so it has the potential for the growth of Saccharomyces cerevisiae. The purpose of this study was to determine wether pineapple waste could produce single cell protein production by adding nutrients to the fermentation medium. The research used in this research is experimental research. To determine the relationship between the independent variable and the dependent variable. Where the independent variables are the addition of nutrients and fermentation time on days 0,2,4,6 to see the dependant variable, namely the analysis of protein content, dry weight analysis of cells, analysis of glucose levels, pH and temperature analysis. The results of this study showed that the highest protein content was obtained in H4 fermentation by MFKN2, namely 0,43%, cell dry weight 0,851 grams, glucose content 1,3402%, ph 4,5, temperature 27,1 ⁰C. Meanwile, MFKN1 showed the highest protein content in H6 fermentation, namely 0,38%, cell dry weight 0,817 grams, glucose content 1,3397%, pH 4, temperature 26,2 ⁰C. The yield of glucose and pH tended to decrease as the fermentation process progressed until the last day of fermentation. The results of the temperature analysis tend to be stable as the fermentation process progresses until the last day of fermentation. The conclusion of this study is that pineapple waste can produced single cell protein from Saccharomyces cerevisiae culture and has different protein production with the addition of nutrients in the fermentation medium.

Introduction: Single Cell Protein (SCP) is a term used for proteins produced from microbes such as bacteria, algae, yeasts, and fungi. One of the fungi known to produce PST is Aspergillus niger. Objective: The purpose of this study was to determine whether pineapple peel waste could produce single cell protein from A. niger culture and to determine differences in protein production with the addition of nutrients in the fermentation medium. Methods: This research method is an experimental method with the independent variables being MFKN1 medium (Pineapple Skin Fermentation Medium with the addition of KH2PO4 and sugar), and MFKN2 medium (Pineapple Skin Fermentation Medium with the addition of KH2PO4, (NH4)2SO4 and sugar); and the length of fermentation time used are days-0, 2, 4, and 6. The dependent variables of this study were analysis of protein content, dry weight of cells, glucose levels, pH and temperature. The data from this study were statistically analyzed using the two way Anova method. Results: The results of this study obtained the highest protein content in MFKN2 media, namely 0.80% (day-2); cell dry weight 0.473 g; glucose level 1.3406%; pH 4.6 and temperature 31 oC. Meanwhile, the highest protein content in MFKN1 media was 0.59% (day- 4); cell dry weight 0.346 g; glucose level 1.3406%; pH 3.7 and temperature 26.6 oC. Conclusion: The conclusion of this study is that pineapple peel waste can produce single cell protein from A. niger culture and there are differences in protein production results with the addition of nutrients, where protein content in MFKN2 medium is higher than protein content in MFKN1 medium.
