Microbacterium sp. CFBb37

While confirming the RS extension by Microbacterium sp. CFBb37 on pools of C. elegans , we noticed that this bacterial strain reduced the average total brood size compared with OP50 (141.6 vs 251.2; P <0.001; Table 1). As above, to remove the potential confounding effects of pooled worms, we recounted the brood sizes using one parental worm per plate. We found that the average total brood size on Microbacterium sp. CFB 37 was less than on OP50 (137.63 mean ± 5.74 SE versus 266.28 ± 6.42; P <0.001, Table 2). Partitioning the data into daily brood sizes over the first 8 days (i.e., the number of days with data for both bacterial strains, Table 2) revealed that worms fed with OP50 had greater brood sizes than those fed with Microbacterium sp. CFB 37 during the first 3 days (29–125 more eggs/day) while the opposite (2–19 fewer eggs/day) occurred during the last 5 days (all P <0.001, Table 2). Although there were more days where worms growing on CBFb37 had greater brood sizes than OP50, the magnitude of the differences was smaller during these 5 days, explaining the lower average total brood sizes for Microbacterium sp. CFB 37.
