This study was conducted to screen ectomycorrhyzal (ECM) fungi that can increase copper (Cu) tolerance of Eucalyptus urophylla and Acacia aulacocarpa seedlings for the phytoremediation of Cu mine tailings. Two laboratory experiments were done following a Completely Randomized Design (CRD) with four replicates. Pisolithus 23-01 yielded the highest mycelial growth and was unaffected by Cu addition up to 750 µM. Likewise, Pisolithus H6394, Scleroderma sp. and Astreus sp. were not affected by Cu but the growth was slower than Pisolithus 23-01. |

Heavy metal contamination is one of the problems encountered by industrialized countries due to its harmful implications. At present, biosorption, a biological method in removing heavy metal ions, is deemed as an inexpensive and effective alternative to physico-chemical methods of separation in treating wastewater contaminated with heavy metal ions. This study Spirulina platensis: Potential Biosorbent for Lead aimed to prove the effectiveness of Spirulina platensis in absorbing lead ions from simulated wastewater. S. platensis and lead acetate were obtained from UPLB. Four separate 90 ml lead solutions, each containing 50 ppm of lead, were prepared and inoculated with 10 ml of S. platensis. |
