“…Members of the bacterium genera Microbacterium and Novosphingobium were identified and isolated from the natural microbial communities inhabiting webs of T. clavata . Members of the genus Novosphingobium are gram negative soil-dwelling bacteria capable of degrading compounds such as phenol, aniline, nitrobenzene and cellulose 47 , 48 . Members of Microbacterium are gram positive bacteria found in soils, insect guts and plant leaves and may exhibit antifungal activities 49 .…”

Spider silk is a promising material with great potential in biomedical applications due to its incredible mechanical properties and resistance to degradation of commercially available bacterial strains. However, little is known about the bacterial communities that may inhabit spider webs and how these microorganisms interact with spider silk. In this study, we exposed two exopolysaccharide-secreting bacteria, isolated from webs of an orb spider, to major ampullate (MA) silk from host spiders. The naturally occurring lipid and glycoprotein surface layers of MA silk were experimentally removed to further probe the interaction between bacteria and silk. Extensibility of major ampullate silk produced by Triconephila clavata that was exposed to either Microbacterium sp. or Novosphigobium sp. was significantly higher than that of silk that was not exposed to bacteria (differed by 58.7%). This strain-enhancing effect was not observed when the lipid and glycoprotein surface layers of MA silks were removed. The presence of exopolysaccharides was detected through NMR from MA silks exposed to these two bacteria but not from those without exposure. Here we report for the first time that exopolysaccharide-secreting bacteria inhabiting spider webs can enhance extensibility of host MA silks and silk surface layers play a vital role in mediating such effects.

“…While the roles of the genera Brevundimonas and Staphylococcus in the biodeterioration of audio-visual materials have been discussed previously, the remaining genera warrant further comment. Cellulolytic activity has been documented for the genus Novosphingobium , and certain species are capable of efficiently degrading lignocellulosic waste ( 34 ). Conversely, the genus Anaerobacillus has been shown to degrade gelatin ( 35 ), and the genus Ralstonia , which was also among the most abundant genera in the study by Szulc et al ( 6 ), has been found to form brown pigments.…”

The existing literature on microbial contamination of audio-visual materials has predominantly used culture-based methods to evaluate contamination and has overlooked the potential impact of environmental factors and material composition on microbial communities. Furthermore, previous studies have mainly focused on contamination by microscopic fungi, neglecting other potentially harmful microorganisms.
