Biodegradation of The Celosiaargentea L. Stems Immersed in Garden Soil

Celosia argentea L. a local weed common in rainfed crop plants of Andhra Pradesh. Biodegradational studies on this weed plant has been carried out. Biodegradation of Celosia argentea L in soil at different time intervals was carried out in laboratory conditions by serial dilution methods. Soil extract Agar media and Martin Rose Bengal Agar media were used to isolate and enumerate the bacteria and fungi from the stem bits. After one month of immersion of the stem (4cmx 0.5cm) in the soil, Aspergillus, Fusarium were isolated. Aspergillus, Fusarium, Penicillum, Rhizopus, Curvularia and Bacillus subtilis were continued to grow around the stem bits after six months and caused complete degradation of the stem bits. The stem got crushed due to mycological succession.
