“…aeruginosa AL98 exhibited adhesive growth towards solid rubbers in an analogous manner like recently shown for some actinomycetes [9,14]. Similar to these bacteria, strain AL98 expressed strong rubber decomposing properties and did not produce any clearing zones (translucent halos) on latex overlay plates like other weaker rubber decomposers isolated previously [4,5,8].…”

A Gram-negative bacterium, strain AL98, was isolated from foul water inside of a deteriorated car tire on a farmer's field in Mu «nster, Germany. The strain was able to considerably disintegrate natural rubber (NR), either in the raw state as NR latex concentrate or in the vulcanized state as NR latex glove, as well as raw synthetic cis-1,4-polyisoprene (IR). Determination of carbon dioxide evolution and living cell number during batch cultivation with each of the materials as sole source of carbon, revealed mineralization of the rubber polymer during biomass increase. Surface investigation by scanning electron microscopy gave evidence for an adhesive growth behavior of the strain proceeding by colonizing the rubber surface, merging into the rubber and forming a biofilm prior to disintegration of the material. Schiff's reagent staining performed with NR latex gloves indicated production and accumulation of aldehyde groups during colonization. The solid glove substrate disappeared completely after a prolonged cultivation period as a result of continuous degradation. Taxonomic analyses of the strain, which were also based on similarity examination of the complete 16S rRNA gene, revealed classification of strain AL98 as a strain of Pseudomonas aeruginosa. This is the first report about the isolation of a Gram-negative bacterium exhibiting strong rubber decomposing properties. ß

“…Both kind of polyisoprene rubbers are known to be susceptible towards microbial action [1–3]. Most NR degrading bacteria were identified as members of the group of actinomycetes [4–10]. There is only one report about treatment of NR latex with the extracellular crude extract of a Gram‐negative bacterium, a Xanthomonas sp., leading to the formation of oligomers with M w 's between 10 3 and 10 4 Da [11].…”

“…Importantly, these materials can be repositioned and reused to maximum capacity over multiple loading cycles without leaving behind a “sticky” residue. Further, these natural fiber fabrics and natural rubber material components are biodegradable . This approach delivers an environmentally‐responsible, high performance reversible adhesive material.…”

Reversible adhesives composed of renewable materials are presented which achieve high force capacities (810 N) while maintaining easy release (∼ 0.25 N) and reusability. These simple, non-tacky adhesives consist of natural rubber impregnated into stiff natural fiber fabrics, including cotton, hemp, and jute. This versatile approach enables a clear method for designs of environmentally-responsible, reversible adhesives for a wide variety of applications.
