Abstract

To investigate the usefulness of Kenaf(Hibiscus cannabinus L.) as mushroom culture media source, we analyze physical condition and contents of nutritional components. The water absorption rate of Kenaf bast was 578% and it was 95% higher than that of poplar sawdust's. This was caused by Kenaf's porous cellular structure. so it could give more moisture and oxygen to cultured mushroom. Total carbon contents of Kenaf was 91.4%, it was quite higher than that of poplar sawdust, wheat bran and rice bran. Total nitrogen content was 1.76% and C/N ratio was 51.9. The content of NFE(Nitrogen free extract) was 46.6% and it was similar with rice bran. Cellulose content was higher than poplar but lignin content was lower. specially hemicellulose and pectin complex which more digestible carbon source to mushroom was 3.7% higher than poplar. Mineral component and amino acid contents were also maintained high compared with poplar. Fe was 4.2 times, P 3.2 times, K 2.2 times more and Ca was higher 16 mg/kg than poplar. The content of amino acid was quite more higher than poplar sawdust but lower than chaff. Consequently Kenaf had a good trait for basic support material in mushroom culture media and also had a good character as nutritional source.
