Abstract

Cassava (Manihot utilissima) is a type of high-carbohydrate plant that grows a lot in Indonesia. One of the most common and simple cassava processing is made into tape. One of the microorganisms in yeast is the genus Saccharomyces. Some species of this genus are considered very important in food production materials. One example is Saccharomyces cerevisiae, which is used in winemaking, bread, and beer. This study aims to: study the cassava fermentation process to obtain alcohol compounds as decomposition materials for acid-forming bacteria, knowing the characteristics of acid-forming bacteria in cassava tape fermentation, and getting isolates of Acetobacter aceti bacteria producing acetic acid in the cassava tape fermentation process. This research uses a qualitative descriptive method, with macroscopic, microscopic observations and gram painting on isolates of acid-forming bacteria that have been selected and successfully isolated from cassava fermentation. The results obtained by the colonies showed clear zones and did not show clear zones. Colonies that show clear zones are colonies that produce acid and react with carbonate ions; in the gram test obtained, a genus of bacteria obtained based on the results of isolation on cassava tape, namely some belonging to the genus Acetobacter with gram-negative (colored red) and some genus Lactobacillus with gram-positive (colored purple). The presence of a sour taste on the tape is caused by acid-forming bacteria after the presence of alcohol by the purples Saccharomyces cerevisiae.

Abstract

The growth of Saccharomyces cerevisiae involves several factors that affect the survival and reproduction of the microorganism, one of which is the carbon substrate that is key to its growth. Fibre sugar-based substrates are glucose-containing materials with residual peroxide. They are often used as a source of nutrients in various biotechnological processes, particularly in bioenergy production, and can be used to support the growth of Saccharomyces cerevisiae. Strawberries (Fragaria sp.) are red due to their rich anthocyanin colour pigment, high in antioxidants and vitamin C. Antioxidants are considered very effective in reducing the action of oxidizers such as hydrogen peroxide (H2O2). This study aims to determine the effect of strawberry juice concentration on the growth of Saccharomyces cerevisiae with peroxide content in the medium. The research method used the randomized block design method, with variations in the concentration of strawberry juice 0%, 5%, 10%, 15%, and 20%, with 7x replicates for 7 days within a period of every 24 hours. The results showed that the content of strawberry juice is needed to increase growth. The 10% concentration had the same growth increase as the 0% extract concentration, but the number of cells was lower at 10,719,205 compared to 21,108,805. There is an effect of strawberry juice antioxidant substances on the growth of Saccharomyces cerevisiae fungal cells at a peroxide concentration of 1000 ppm in the medium.  Keywords: Saccharomyces cerevisiae, Hydrogen peroxide, strawberry, turbidimeter Pertumbuhan Saccharomyces cerevisiae melibatkan beberapa faktor yang mempengaruhi kelangsungan hidup dan reproduksi mikroorganisme tersebut, salah satunya yaitu substrat karbon yang menjadi kunci untuk pertumbuhannya.
