Earlier work by the authors has shown that batch anaerobic digestion of waste milk and cattle slurry is feasible at COD loadings of up to 29.3 kg COD m−3. Higher COD loadings were added to batch anaerobic digestion systems in an attempt to determin

Continuous cultivation of Bacillus amyloliquefaciens B155 using a defined synthetic medium, which supports good batch cell growth and α-amylase production, was limited by lactose, nitrogen, phosphorus and oxygen. In each case, the organism changed t

The xylanolytic enzymes xylanase and β-D-xylosidase from Aspergillus fumigatus IMI 255091 have temperature optima of 70°C and pH optima lying over a broad range between 4.0 and 7.0. Thermal stability of these enzymes and stability at various pH val

Since the mixing characteristics of anaerobic reactors would appear to have an effect on their operational performance, lithium tracer studies were made on two different digester types; the upflow sludge blanket and the expanded bed reactors. The mix

The concentration of several surface active agents required to inhibit the initiation of growth ofAspergillus foetidus in both solid and liquid media was estimated. The culturing in liquid media involved both shake flask and fermenter cultures.

A total of 11 tissue culture media and one synthetic medium were screened to determine whether they could support the growth of two strains of Acholeplasma. Two similar chemically defined media were found in which Acholeplasma laidlawii Strain A (Buc

Contamination of the porous-plate gas distributor was observed in an air-lift fermentor used for Aspergillus fumigatus fermentations. Comparisons between gas holdups measured with uncontaminated distributors and the contaminated one showed that the c
