The effects of bacterial degradation will be similar to the effects of BRF, with only minor alteration of the lignin. Unlike fungal degradation, bacterial degradation can also occur under anoxic conditions, such as the interior of wooden artifacts . SRF and bacteria are likely drivers of the degradation of submerged timbers; however, once the timbers are exposed to air and no longer waterlogged, the more destructive WRF could become active.
