  • The possible inhibitory effect of wood hydrolyzate in lactic acid fermentation was partially decreased by adaptation of Enterococcus faecalis RKY1 to wood hydrolyzate-based medium. The strain RKY1 grown on wood hydrolyzate-based medium was tolerant to wood hydrolyzate medium with fermentation efficiency being improved to approximately 20% higher than that obtained with the strain RKY1 grown on glucose-based medium.

  • The concept of AOQL in designing Dodge's continuous sampling plans is modified to include probabilistic consideration reflecting the prior knowledge about the process average fraction defectives, and a new design criterion called AOQL, which eliminates some of the drawbacks of the AOQL criterion is proposed. AOQL, approach provides more economical sampling plans in many cases, and can be used even when only limited amount of prior information is available.
