Title: John William Costerton: Innovator in Biofilm Remediation
Introduction
John William Costerton is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of biofilm remediation, holding a total of 3 patents. His innovative methods focus on addressing environmental challenges, particularly in the context of acid mine drainage and contaminated fracture fluid.
Latest Patents
Costerton's latest patents include groundbreaking methods for biofilm remediation. One of his patents, titled "Biofilm remediation of acid mine drainage," presents a method for preventing acid rock drainage. This method involves building an oxygen bio-barrier over exposed surfaces of waste rock that contain ferrous sulfides. The bio-barrier is formed by applying a slurry to the rock, which may contain microbial material, nutrients, water, and optional water-absorbent materials. The microbial material can include bacteria, algae, fungi, or a combination thereof. Additionally, the slurry may incorporate acid-neutralizing compounds, cellulose-containing substances, and UV protecting agents.
Another significant patent is "Biofilm remediation of fracture fluid," which details an in situ treatment method for fracture fluid contaminated with heavy metals. This method involves passing contaminated fracture fluid through a reactor vessel containing biofilm retaining structures. Each structure is partially coated with a biofilm that includes a matrix of DNA, protein, and carbohydrates produced by the bacteria.
