The aim of this study is to present the time dynamics of biological pretreatment studies used for biogas processes in a systematic and comprehensive manner. The data obtained from the research articles is illustrated using a visual mapping approach. In this study, it was understood that bioinformatics studies on microorganisms used in systems/processes where microorganisms are used in biogas have recently increased. However, the genetic studies used are generally for the detection of microorganisms in the consortium and controlled gene exchange with cloning processes in biogas fields. Therefore, it is concluded that studies on cloning processes, which are required by biological pre-treatments used in biogas, should be given importance, and studies on these issues should be increased. However, genetic studies in biogas processes are not used for controlled gene exchange with cloning processes. It is understood that it is generally used for the species identification of microorganisms. Therefore, it is concluded that studies on cloning processes, which are required by biological pre-treatments used in biogas processes, should be given importance, and studies on these issues should be increased.
