This study titled "Microbial Analysis of Rabbit Skin Decomposition in Different Soil Compositions" focuses on understanding how varying soil compositions influence microbial activity during decomposition. The study was conducted over a period of 28 days, with observations recorded at seven-day intervals. Rabbit skin was used as the biological material to simulate soft tissue decomposition under natural soil conditions. Three distinct soil types—alluvial, black, and red soil were selected based on their contrasting physical and chemical properties. The analysis included bacterial staining, fungal staining, and pH measurement to assess microbial growth and environmental changes throughout the decomposition process. The results revealed significant differences in microbial activity among the soil types. Alluvial soil showed the highest microbial presence due to its nutrient-rich and well-balanced structure. Black soil exhibited moderate microbial growth, while red soil demonstrated the least activity, likely due to its low organic content and acidic nature. This study highlights the crucial role of soil type in influencing decomposition and microbial succession. The findings offer valuable insights for forensic applications, particularly in estimating the postmortem interval and understanding the decomposition process in various environmental conditions.
