The cellophane membrane lying on organic C and N deficient mineral solid medium was successfully established in order to resynthesize lichen and could be used to screen adequate lichens as well as to examine the conditional factors in the laboratory. The colonization of lichen on stones, such as flat rock fragments or sands, offers the possibility of reclaiming areas of flat rock fragments or deserted non-cultivable land. We have propose synchronized culture technology which focuses on the first peak harvest for mushroom growing. Synchronized culture technology will significantly reduce the loss of substrate moisture, the size of mushroom farms and the capital investment required. A technology mimic of SSF has also been proposed to prevent the loss of cultivable lands by reducing nitrate pollution. We have found that detection of the appearance of geosmin can be used as an index for detection of the maturation of hog waste compost, which is a useful bioresource. We have also detected aromatic volatiles from sorghum mashes during sorghum brewing (a SSF) and a tasty oligopeptide produced during sweet wheat paste (Tieng-Meng Chiang) brewing (another SSF) using facultative anaerobic fungi. Both have potential economic value as natural flavors. All these approaches will eventually lead to the development of new bioresources or possible reclamation of bioresources. On the other hand, head space gas analysis and geosmin have enabled this laboratory to develop gas sensors and to realize the importance of breath fingerprints or the distribution of volatile fermentation products of SSF and even those of human breath if breath is used as head space gas. This evidence has motivated us to search for one or some particular volatile(s) to define human health. The developed or proposed technology of SSF presented here will change the nature of SSF from appropriate technology to high technology.
