Microbial degradation of paintings

Article Abstract:

Paintings contain various organic and inorganic materials that serve as ecological niches where microorganisms could thrive. These substances along with the additives are biodegradable. Easel paintings also have organic molecules such as sugar, gums, polysaccharides, proteins, linseed and other oils which microorganisms may utilize as nutrients. The microbial flora commonly found on paintings include fungi species such as Penicillium, Aspergillus, Cladosporium, Chaetomium and Alternaria and bacteria species such as Pseudomonas, Arthrobacter and Streptomyces.

Metal toxicity reduction in naphthalene biodegradation by use of metal-chelating adsorbents

Article Abstract:

The inhibitory effect of cadmium on the growth of Pseudomonas putida ppo200(NAH) solely for naphthalene biodegradation was assessed. Findings indicated that the toxicity of cadmium to P. putida can be largely decreased by introducing a modified-clay complex or a commercial chelating resin. Also, the decrease in metal toxicity is quantitatively correlated with the adsorption characteristics of the adsorbents.

Initial colonization, nutrient supply, and fungal activity on leaves decaying in streams

Article Abstract:

Fungal decomposition of leaves in streams is stimulated by inorganic nitrogen and phosphorus. This in turn provides greater biomass for aquatic leaf-eating invertebrates.
