[Isolation and identification of rumen bacteria for cellulolytic enzyme production].

Objective: We screened aerobic bacteria with cellulolytic activity from ruminal fluid of sheep, cattle and camel in Xinjiang.

Method: Fresh ruminal fluid was inoculated on sterilized sodium carboxymethylcellulose agar plates. Highly cellulolytic aerobic bacteria were screened out by using Congo red staining and liquid secondary screening culture media.

Evaluation of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) conduits for peripheral nerve regeneration.

Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) was investigated for possible application in repairing damaged nerves. Porous nerve conduits with both uniform wall porosity and non-uniform wall porosity were prepared using a particle leaching method. Adult Sprague-Dawley (SD) rats weighing 200-250 g were used as the animal model.
