The negative correlation between hi

The negative correlation between high protein contentof mushrooms (PO, PC) and low C/N ratio of substrate(Fig. 1E) implies that nitrogen is essential for synthesis ofprotein in mushroom fruiting bodies. This result was inline with Ragunathan and Swaminathan [46], the proteincontents of mushroom depended on biological, chemicaldifferences and the C/N ratio of substrates. Wang et al.[40] reported that not only protein content in fruitingbody but also nature of protein were affected by substrateused. The result was confirmed with the finding of Mshandeteand Cuff [47] that protein content of edible mushroomswas influenced by species/train specific and the growingsubstrate
