• A. Rhodococcus equi
• B. Pseudomonas species
• C. Ochrobacterum species
• D. All of the above

Answer 1

The correct option is D All of the above

The research for biodegradable plastics that are derived from renewable resources has been ongoing since the 1970s. Biodegradable plastics are polylactic acid and polyhydroxyalkanoates, These are obtained from Rhodococcus equi, a Gram-positive coccobacillus bacterium. Other bacteria from which biodegradable plastic can be obtained include Bacillus subtilis, Aspergillus species, Penicillium species, Pseudomonas species, Staphylococcus aureus, Streptococcus species, Proteus vulgaris, Ochrobacterum species.

Thus, the correct answer is 'All the above.'
