In this review, microbial and enzymatic biodegradation of plastics and some factors that affect their biodegradability are discussed.
Distribution of poly(β-hydroxybutyrate) and poly(ε-caprolactone)aerobic degrading microorganisms in different environments
To assess the capacity of the natural environment for degrading plastics, the populations of poly(β-hydroxybutyrate)(PHB)-and poly(e-caprolactone)(PCL)-degrading aerobic microorganisms and their…
Three isolates of novel polyphosphate-accumulating gram-positive cocci, obtained from activated sludge, belong to a new genus, Tetrasphaera gen. nov., and description of two new species, Tetrasphaera…
Two isolates of Gram-positive cocci which could accumulate polyphosphate and were microscopically similar in appearance to so-called 'G-bacteria', appearing as tetrads, were isolated from samples of activated sludge biomass by micromanipulation and grown in axenic culture, suggesting that they belong to a new genus Tetrasphaera gen. nov.

Thirty-nine morphologically different soil bacteria capable of degrading poly(β-hydroxyalkanoate, poly(ɛ-caprolactone), poly(hexamethylene carbonate), or poly(tetramethylene succinate) were isolated and determination of substrate utilization revealed characteristic patterns of substrate specificities.
A Novel PHB Depolymerase from a Thermophilic Streptomyces Sp.
A novel PHB depolymerase from a thermophilic Streptomyces sp. MG was purified to homogeneity by hydrophobic interaction chromatography and gel filtration. The molecular mass of the purified enzyme…

A short overview on the biodegradability and biodegradation of PLA is provided, focused mainly on microbial and enzymatic degradation.
Polylactide Degradation by an Amycolatopsis sp
By applying the plate count and clear-zone methods, it was confirmed that polylactide (PLA)-degrading microorganisms are sparsely distributed in soil environments. An Amycolatopsis isolate was…
Roseateles depolymerans gen. nov., sp. nov., a new bacteriochlorophyll a-containing obligate aerobe belonging to the beta-subclass of the Proteobacteria.

Genetic and phenotypic features suggest that the strains represent a new genus in the beta-subclass which is evenly distant from known genera, and the name Roseateles depolymerans gen. nov., sp.
Efficient production of D-(-)-lactic acid from broken rice by Lactobacillus delbrueckii using Ca(OH)2 as a neutralizing agent.
Poly(L‐lactide)‐Degrading Activity in Various Actinomycetes
The poly(L-lactide) (PLA)-degrading ability of actinomycetes obtained from culture collections was examined by the formation of clear zones on PLA-emulsified agar plates and Saccharothrix species showed an ability to degrade PLA films and assimilate degradation products in liquid cultures.
