Abstract

Oyster mushroom as a source of nutritious food and medicinal source is known since Chow Dynasti in China.However, its potential for environmental rehabilitation as known as mycorestoration is being investigatedby Paul Stamets in 2005. If oyster mushroom can control the world that could support from the smallestthings as food becoming bigger roles in the future, such as poverty eradication, improving soil fertility, andrehabilitating environmental condition, degrading toxic pollutant, protecting human health from diseases,and helping community to integrate complex waste recycle, so oyster mushroom is emerging as a strongcommodity to improve our welfare. This paper is trying to promote the role of oyster mushroom to provideits strength for both as nutrious food and medicinal source, and also for its ability to restore degraded soilfertility, and improving to remediate contaminated soils. In line with those things, and the most importantfor the people of Indonesia is trying to help increase their income through promoting mushroom cultivation,because Indonesia has a hugh potential for lignocelluslose materials and agricultural waste, and then itsspent mushroom can be used for animal feed and soil amelioration and soil remediation. Based on theStamet investigation this spent mushroom can be used for environmental rehabilitation of toxic pollutantssuch as PCB (Polychlorinated Biphenils), PAH (Polycyclic Aromatic Hydrocarbon), Azo dyes, and otherpersistent organic pollutants (POP’s).Key words:  Oyster mushroom, Pleurotus ostreatus, mycorestoration, soil remediation, environmentalrehabilitation.

Abstract

Oyster mushroom beta glucan has potential as a healthy drink. The purpose of this research is to increase the amount of beta glucan derived from the extraction of oyster mushroom (Pleurotus ostreatus). Beta glucan extraction was done by boiling oyster mushrooms for an hour (60 minutes). To increase the yield of beta glucan production, the extraction has been repeated three times and the results of the extraction of so- called filtrate I, II and filtrate filtrate III. Beta-glucan was produced, and were analized using Megazyme and as a standard method used Yeast and beta glucan levels in packaging contained 58.5% (w / w). The results showed that the first filtrate with the highest viscosity to produce the highest levels of beta-glucan which is 0.7559% (w / w), filtrate II produced beta glucan levels of 0.0904% (w / w), while filtrate III produced the lowest levels of beta-glucan 0.0161% (w / w). From the data obtained in this study suggested that the second and third extraction are not necessary, because the results were very small.Beta glukan jamur tiram mempunyai potensi sebagai bahan minuman kesehatan. Tujuan penelitian ini dalam rangka ingin meningkatkan jumlah beta glukan yang diperoleh dari hasil ekstraksi beta glukan dari jamur tiram (Pleurotus ostreatus). Ekstraksi beta glukan dilakukan dengan cara perebusan tudung jamur tiram selama satu jam (60 menit). Untuk meningkatkan hasil beta glukan yang dihasilkan, telah dilakukan ekstraksi secara berulang sebanyak tiga kali dan hasil ekstraksi tersebut disebut Filtrat I, Filtrat II dan Filtrat III. Beta-glukan yang dihasilkan, dianaliasa dengan menggunakan metode Megazyme dan sebagai standar digunakan Yeast dengan kadar beta glukan dalam kemasan 58,5 % (b/b). Hasil percobaan menunjukkan bahwa Filtrat I dengan kekentalan tertinggi menghasilkan kadar beta-glukan tertinggi yakni 0,7559 % (b/b), Filtrat II dengan kadar beta glukan 0,0904 % (b/b), sedangkan Filtrat III menghasilkan kadar beta-glukan 0,0161 % (b/b). Dari data yang diperoleh disarankan bahwa ekstraksi kedua dan ketiga tidak perlu dilakukan, karena hasilnya relatif sangat kecil.Keywords: Oyster mushroom (Pleurotus ostreatus), filtrate, levels of beta-glucan
