摘要: Abstract Batch experiments were carried out to examine the productions of hydrogen and volatile fatty acids from glucose by enriched anaerobic culture in presence Cu Zn. Results showed specific production rate was enhanced dosage at 50–100 mg/dm3 or Zn 10–250 mg/dm3, but inhibited over 200 mg/dm3 500 mg/dm3. The yield 5–400 mg/dm3 5–500 mg/dm3. Productions acetate propionate On other hand, butyrate stimulated, whereas ethanol not affected. In terms CI,50 values, more toxic than modified Gompertz equation able properly describe cumulative
