Objective of this work was to study microorganisms involving in organic fertilizer manufactured by Biofertilizer plant of Takam subdistrict administration rganization, Amphoe Hat Yai, Songkhla Province by using two approaches, namely, culture-dependent technique and rRNA techniques (16S rRNA clone library analysis). It was found that the culture-dependent technique showed the changes in number of microorganism involved in different production processes which mainly were bacteria and actinomycetes. Most of them are thermoduric or thermophilic microorganism. In contrast, the dominance of Halomonas-like bacteria (48 percent) and also some unculturable bacteria (17 percent) were detected when using 16S rRNA clone library analysis. Therefore, it is expected to obtain more information regard to the determination of microbial ecology in the organic fertilizer production process.
