I want to know the answer to the following question:
How long was the wood submerged in water in the study that discovered the types of bacteria in it?
All the background I'm provided with is that "Symbiotic bacteria in Xylophaga may play a role in the degradation of sunken wood; while bacteria such as Alphaproteobacteria, Flavobacteria, Actinobacteria, Clostridia, and Bacteroidetes have been detected in wood submerged over a year.". Is that enough to answer the question?
