Bacterial community variations in hot pepper-sown soil using FAME analysis as an indicator of soil quality

The bacterial compositions of seven hot-pepper sown soil were compared in this study. From the 624 isolates, 95 species and 49 genera were identified by fatty acid methyl ester analysis (FAME). The FAME results of seven soil showed two distinct clusters for aerobic and Gram-negative bacteria in the high productivity and monoculture soil samples. While Arthrobacter (17%), Kocuria (11%). Pseudomonas (8%), and Bacillus (8%) were predominant among bacteria which were cultured on heterotrophic (YG) agar medium, Pseudomonas (56%), Stenotrophomonas (16%), and Burkholderia (8%) were predominant on crystal violet agar medium Shannon-Weaver indices (H) indicated that colonies obtained from heterotrophic agar medium (3.1 ) were found to be more diverse than those obtained from the crystal violet media (1.9). The results suggest that FAME analysis may he a potential indicator of soil quality.
