An Austin man who is accused of carrying a portable meth lab in his backpack has pleaded not guilty to two felony drug charges.

Jacob Harm Wilde, 33, pleaded not guilty to fifth-degree drug possession and possessing meth precursors with intent to manufacture Thursday in Mower County Court. His jury trial is scheduled to begin Aug. 15.

Wilde was arrested April 21 on a warrant. When police were in pursuit of him, one officer said he saw Wilde with a backpack. The backpack was found and contained a Southern Comfort liquor bottle one-third full with a liquid that tested positive for ammonia.

According to court documents, the bag also contained clear plastic tubing and a straw that tested positive for meth, along with coffee filters, mason jars, lithium batteries and an unopened bottle of muriatic acid.

Wilde is scheduled for sentencing in a previous Mower County drug crime May 20.
