Compositions and methods of making a culture medium from a polymeric material are described herein. The method can include (a) depolymerizing and/or dispersing the polymeric material to obtain a depolymerized and/or dispersed residue, and (b) combining the depolymerized and/or dispersed residue with one or more adjuvants to form a culture medium. In some embodiments, the polymeric material can be a plastic article, such as a waste carpet material. Culture media prepared from the compositions and methods are also described. The culture media are suitable for culturing microorganisms including bacterium, algae, and fungus. The microorganisms can be used to produce a bioproduct such as a biopolymer, an enzyme, or a cellular metabolite.

Polymer recycling

According to various implementations, the bioreactor system includes a bioreactor vessel, an impeller for stirring contents within the vessel, a temperature control source for controlling the temperature of the contents of the vessel, an aeration system for supplying air to the vessel, and one or more data loggers. According to certain implementations, the impeller is a novel impeller design that spins more smoothly and rapidly than known impellers. In addition, the bioreactor system is modular, durable, and relatively inexpensive compared to existing bioreactor systems, which allows for bench-scale implementation, use with differently sized bioreactor vessels, and accessibility to more educational programs, according to some implementations.

This disclosure relates to conjugates for targeting bacteria and related uses. In certain embodiments, the disclosure relates to methods of transferring a molecule of interest into bacteria comprising mixing bacteria with a non-naturally occurring conjugate under conditions such that the conjugate is transported across the bacterial cell wall. Typically, the conjugate comprises an oligosaccharide and a molecule of interest. In certain embodiments, the molecule of interest may be a tracer or an antibiotic.
