Table 2.

Effect of the various pH levels on P. ostreatus mycelial growth over the culture period (days).

pH level	Mycelium colony diameter (mm/day)
	4 th day	6 th day
pH 4	30.80 ± 0.70a	63.89 ± 0.63b
pH 5	32.67 ± 0.47b	64.33 ± 2.62b
pH 6	35.33 ± 0.85c	74.61 ± 0.63c
pH 7	33.23 ± 0.63b	64.35 ± 1.93b
pH 8	29.33 ± 0.42a	57.56 ± 0.97a

Note: Values are means ± SD of triplicate samples. Values within the same column of each mycelial growth on each incubation day followed by the same letters are not significantly different at p ≤ 0.05 according to Duncan's multiple range test.
