Lactic acid bacteria are beneficial bacteria for the health of the body by improving the balance of the intestinal microflora. Lactic acid bacteria can generally be isolated from fermented foods, fruits, vegetables and meat. Inasua is a traditional fermented fish product originating from Central Maluku (Teon, Nila and Serua islands) wherein the fermentation process is carried out at room temperature for a certain time. The purpose of this study was isolation and identification based on the morphological characteristics of lactic acid bacteria in inasua. Isolation of Lactic Acid Bacteria was carried out using the pour plate method and the streak method on the media de Man, Rogosa and Sharpe Agar (MRSA) and Nutrient Agar media. The culture was incubated at 370C for 48 hours. The growing colonies were observed for morphological characteristics and GRAM staining of bacteria was carried out. The results of isolation of BAL from inasua in the media de Man, Ragosa and Sharpe Agar (MRSA) + CaCO3 obtained 4 bacterial isolates, namely INS-A1, INS-A2, INS-A3 and INS-A4 and only 2 isolates that have the characteristics of positive GRAM with Bacillus forms, namely INS-A2 and INS-A4. It is suspected that the 2 isolates were isolates of Lactic Acid Bacteria. The results of isolation on Nutrient Agar (NA) media contained 5 isolates namely INS-B1, INS-B2, INS B3, INS-B4, INS-B5 which have characteristics as negative GRAM shaped Bacillus

Bioethanol can be produced by the fermentation using microorganisms such as yeast. The type of yeast that can produce bioethanol is still limited to certain yeast types such as Saccharomyces cerevisiae. Isolation and characterization of yeast need to be done to determine yeast isolates capable of producing bioethanol. Yeast can grow on a substrate that is rich in sugar as in the apple fruit. Enzymatic tests can support the ability to use on various substrates. This study aims to isolation, characterization, and enzymatic tests of yeast from apple that potential to produce bioethanol based on morphological and biochemical tests. The isolation method is done by using spread plates on PDA media. Morphological tests are carried out by making macroscopic (form, color, elevation, margin, the texture of colonies) and microscopic (form, budding, size of cells)observations of colonies and yeast cells. The growth was carried out on PDA at 6, 28, 37ᵒC, and also 50% glucose observed, Carbohydrate fermentation test (glucose, maltose, sucrose, lactose), and urease were used to the biochemicals characterization. Enzymatic tests were using amylase test, protease test, lipase test, and cellulase test. The bioethanol was measured bypycnometer method. The results of yeast isolation from apples were obtained 3 isolates, namely K1, K2, K3 with cell size 3,74 µm, 3,79 µm, and 3,41 µm respectively. Enzymatic test results showed that the presence of amylase enzyme activity in yeast.

Angkak (red fungi rice, red yeast rice) is a traditional fermentation by fungi Monascus in a lot of Asia Countries, which is useful as a natural food colorant. The aim of this research was to obtain pure isolate of red fungus from angkak in Semarang. The growth and the red pigment production of the selected isolate in the different initial medium pH and nitrogen sources were observed. The treatment was done by growing the isolate in PDB (Potato Dextrose Broth) medium at initial pH 3, 5, 7 and 9 and as well as optimization of nitrogen sources with 1% ammonium chloride, 1% ammonium nitrate, and 1% peptone. Analysis of the fungi growth was performed by weighing mycelia biomass using dry weight method and the red pigments were analysis using spectrophotometer at a wavelength (λmax) of 500 nm. The results showed that the highest absorbance value of pigment (0.81) was obtained at pH 7, and the highest value of the cell dry weight was also obtained at pH 7 (1.23 g/L). The results showed that 1% ammonium chloride was the best nitrogen source for absorbance of red pigment production (0.82), but the highest of dry weight (2.56 g/L) was obtained by using medium with 1% ammonium nitrate as a nitrogen source.

Kempong is a traditional fermented food that is found only in South Karangpucung Linggapura Bumiayu village, Central Java. It is prepared from palm kernel cake (PKC). This fermented food is consumed mostly everyday by the people in the village as a side dish or snack. Study on the mold important in the kempong fermentation was done by isolating molds from kempong, PKC, laru and the air of preparation room. Eleven species of molds were successfully isolated from different samples. Among the mold isolates three species came out from kempong product, i.e. R. oryzae, E. chevaliery and A. oryzae. The isolates showed the capability in producing amylase, protease, lipase, and cellulase. Both R. oryzae and A. oryzae indicated as the main fermentation mold in kempong production, because the inoculum laru only contained these two species.
