Abstract

A preliminary study was conducted to identify the amount and changes of biochemical composition of different types of Malaysian spent mushroom substrate (SMS) before and after several cycle of mushroom cultivation. The characterization of SMS involved the analysis of crude protein, carbohydrate, fat, lignin and ash for selected mushrooms namely as white oyster (Pleuratos ostreatus), grey oyster (Pleuratos sajor-caju), abalone (Pleuratos cystidiosus), ganoderma (Ganoderma lucidium) and black jelly (Auricularia polytricha). Overall trend showed that there were increment for crude protein and fat, whereas carbohydrate and lignin showed reduction in the content. Significant results were showed on protein increment where ganoderma attained the highest value, 36.6 g, followed by black jelly, white oyster, grey oyster and abalone. Contradictory, lowest carbohydrate reduction was observed in ganoderma at 70.42 g and the most was in black jelly. Increment in fat and reduction in lignin was almost similar for each SMS. There was an increment in the ash percentage resulted from sterilization process. Clearly cultivation by mushroom had changed biochemical value especially in increasing the protein content that might be useful in protein required industry such as animal feeding.

Abstrak

Satu kajian awal telah dijalankan untuk mengenalpasti jumlah dan perubahan komposisi biokimia pelbagai jenis sisa substrat Cendawan (SMS) di Malaysia sebelum dan selepas beberapa kitaran tuaian cendawan. Pengkriteriaan SMS melibatkan analisis seperti protein mentah, karbohidrat, lemak, lignin dan abu untuk cendawan yang terpilih seperti tiram putih (Pleuratos ostreatus), tiram kelabu (Pleuratos sajor-caju), abalon (Pleuratos cystidiosus), ganoderma (Ganoderma lucidium) and telinga kera (Auricularia polytricha). Tren keseluruhan menunjukkan terdapat peningkatan untuk protein mentah dan lemak manakala karbohidrat dan lignin menunjukkan penurunan di dalam kandungan. Keputusan yang signifikasi telah ditunjukkan di dalam peningkatan protein di mana ganoderma mencapai jumlah tertinggi, 26.6 g diikuti cendawan telinga kera, tiram putih, tiram kelabu dan abalon. Sebaliknya, jumlah penurunanan karbohidrat yang terendah direkodkan di dalam ganoderma sebanyak 70.4 g dan kebanyakannya di dalam cendawan telinga kera. Peningkatan lemak dan penurunan di dalam lignin menunjukkan keputusan yang hampir sama bagi setiap SMS. Terdapat peningkatan peratus abu yang disebabkan daripada proses steril. Jelas menunjukkan bahawa proses tuaian oleh cendawan telah mengakibatkan perubahan daripada segi komposisi biokimia terutamanya di dalam peningkatan jumlah protein yang mungkin berguna di dalam industri yang memerlukan protein seperti makanan haiwan.
