Some characteristics of lipases from thermophilic fungi isolated from palm oil mill effluent

Rhizopus oryzae and Rhizopus rhizopodiformis are thermophilic fungi isolated from palm oil mill effluent (POME). They are able to grow up to 50°C and produce remarkable amounts of extracellular lipases. The extracellular lipases from both fungi displayed quite similar characteristics. The optimum pH...
