abstract = "Liquid effluents of oil refinery contain toxic selenium oxyanions and phenol, while gaseous effluents contain toxic CO/syngas. To remove the phenol and simultaneously reduce the selenite oxyanions, a fungal-bacterial co-culture of Phanerochaete chrysosporium and Delftia lacustris was developed. Two modes of co-cultures of the fungus and the bacterium were developed. The first being a freely growing bacterium and fungus (suspended growth co-culture), the second being the growth of the bacterial biomass encircling the fungal biomass (attached growth co-culture). Both types of fungal-bacterial co-cultures were incubated with varying concentrations of phenols with a fixed selenite concentration (10 mg/L). The suspended growth co-culture could degrade up to 800 mg/L of phenol and simultaneously reduce 10 mg/L of selenite with production of nano Se(0) having a minimum diameter of 3.58 nanometer. The attached growth co-culture could completely degrade 50 mg/L of phenol and simultaneously reduce selenite to nano Se(0) having a minimum diameter of 58.5 nm. In order to valorize the CO/syngas by bioconversion techniques an anaerobic methanogenic sludge was acclimatized to use CO as sole carbon substrate for a period of 46 days in a continuous stirred stank reactor, supplied with CO at 10 ml/min. 6.18 g/L acetic acid, 1.18 g/L butyric acid, and 0.423 g/L hexanoic acid were the highest concentrations of metabolites produced.
