  • Abstract:

The natural ability of Lentinus squarrosulus (Mont.) Singer to utilize inorganic
metals as a bioremediation agent in a Nigerian brewery waste-water (WW) was investigated. The
results obtained showed that the levels of inorganic metals assessed, Na, Ca, Mg, Zn, Co, Cu, Cd, P,
and Pb except K, in the brewery WW was significantly reduced when inoculated with L.
squarrosulus, after incubation periods of 5, 10, 15, 20 and 25 days. It was also observed that levels
of the minerals (except Na and K) in the pure strain of L. squarrosulus were significantly reduced
in the mycelia but Na was significantly increased while that of K was constant. There was an
increase in the mycelia biomass from incubation period of day 5 (0.86 mg/g ±0.309) to a peak at day
10 (0.90mg/g ±0.316) with a fall at day15 (0.85mg/g ±0.397), and no significant mycelia growth
was observed at day 20 (0.15mg/g ±0.000) and day 25 (0.001 ±0.000) respectively. This study
revealed that L. squarrosulus could bioaccumulate and tolerate non- essential metals such as Pb
and Cd. The fungus L. squarrosulus (Mont.) Singer, an indigenous Nigerian mushroom used in
this study, was observed to posses the potential for biosorption of inorganic metals in brewery
wastewater, and therefore, it could help in bioremediation of non-essential metals and metal toxicity
for a safe environment and improved health
