In order to evaluate the biological activities of some fractions from the fungal(Pleurotus sajorcaju) fermentation products of sugar cane bagasses, the antimutagenicity, the glyceollin elicitor activity on soybean and the effect on the stem elongation in pea were observed. The alcohol extract fraction and DMSO soluble fraction had excellent antimutagenicity even though it is weaker than that of the extracts from the fruiting bodies. All of the extracts had the ability to elicit glyceollins in soybean cotyledons and these extracts could be helpful for plants to protect themselves from pathogenic contaminations. IAA and the extracts had shown synergistic effects on pea stem elongation in all experimental groups positively determined.

Currently, bioethanol, a fuel additive for transportation, is produced mainly by using biomass (first generation) such as corn and sugar canes. First generation biomass can cause various problems in terms of increase in agricultural prices and ethical reasons. To address these problems, a nonedible lignocellulosic biomass can be utilized. Agricultural byproducts such as straw, bagasse, and forest byproducts from the wood processing industry. Therefore, production of wood based bioethanol can be an effective utilization route of second generation biomass, and its raw materials are more abundant than first generation resources. Furthermore, it is possible to secure cheap raw materials. One of the biggest advantages of using biofuels is that it contributes to the reduction of greenhouse gases by minimizing the environmental impact, unlike fossil fuels. In this study, we investigated the greenhouse gas reduction effects that can be achieved through the use of Lignocellulosic bioethanol and government policies on renewable energy currently being implemented in ASEAN countries (Indonesia, Malaysia, Thailand and the Philippines). In these four countries, policies and incentives related to biofuels have been developed. It is expected that the reduction ratio of carbon dioxide emission and the mixed biofuel will be gradually increased in the future.
