Here, we compared the microbial recolonization patterns of a  disturbed, autoclaved soil using different amounts of the original  non-disturbed soil as inoculum. By using this approach, we manipulated  microbial biomass, but did not change microbial diversity of the  inoculum. We followed the development of a new soil microbiome after  reinoculation over a period of 4 weeks using a molecular barcoding  approach as well as qPCR. Focus was given on the assessment of bacteria  and archaea. We could show that 1 week after inoculation in all  inoculated treatments bacterial biomass exceeded the values from the  original soil as a consequence of high dissolved organic carbon (DOC)  concentrations in the disturbed soil resulting from the disturbance.  This high biomass was persistent over the complete experimental period.  In line with the high DOC concentrations, in the first 2 weeks of  incubation, copiotrophic bacteria dominated the community, which derived  from the inoculum used. Only in the disturbed control soils which did  not receive a microbial inoculum, recolonization pattern differed. In  contrast, archaeal biomass did not recover over the experimental period  and recolonization was strongly triggered by amount of inoculated  original soil added. Interestingly, the variability between replicates  of the same inoculation density decreased with increasing biomass in the  inoculum, indicating a deterministic development of soil microbiomes if  higher numbers of cells are used for reinoculation. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"605\" src=\"\/wp-content\/uploads\/image-220-1024x605.png\" alt=\"\" class=\"wp-image-4446\" srcset=\"\/wp-content\/uploads\/image-220-1024x605.png 1024w, \/wp-content\/uploads\/image-220-300x177.png 300w, \/wp-content\/uploads\/image-220-768x454.png 768w, \/wp-content\/uploads\/image-220.png 1168w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h4>Reference:<\/h4>\n\n\n\n<p>Pinheiro Alves de Souza, Y., M.
