Abstract

The production of white oyster mushroom with a variation of load time baglog after an incubation period has been investigated. Based on the results obtained FTIR molecular C-O, C=O, C-H, and O-H on oyster mushrooms. Molecules C-O, C=O, and C-H indicates carbohydrates and O-H molecules indicate the presence of water. The results obtained from the characterization of Fourier Transform Infrared showed the opening day 35th after incubation mass has a moisture content which is small compared with the opening day 40th day and the 45th day. These results indicated a high transmittance value on the FTIR graph results. Keywords: FTIR, O-H cluster, white oyster mushroom, transmittance

Abstract

The successful establishment of oyster mushroom seeds depend on Potato Dextrose Agar (PDA). In this study,the sterilization level of media varied from level 1 to 3. For each sterilization level, PDA were steamed at 102 0C for 60 minutes. The best result was found at third level that was showed by growing of mycelium. All of spread seeds (F1) produced were good and not contaminated. The result of growing spread seeds by using sorghum media were not contaminated. The characterization result of FTIR mycelium from pure culture (F0), spread seeds (F1), and planting seeds (F2) indicated the stretching vibration. Stretching vibration showed of several functional groups. They were C-O, C-N, C=O, C-H, O-H, and β-D-glukan. Keywords: FTIR, functional groups, mycelium, sorghum media.
