DIVERSITY OF SPORE-FORMING BACTERIA IN MARINE SEDIMENTS BELOW FISH-CAGE
网箱养殖海区底泥产芽孢细菌多样性

Spore-forming bacteria have been widely studied for their capability to secrete various extracellular enzymes such as proteaes,amylase etc.,but less for their distribution and ecological roles in natural environment.The diversity of spore-forming bacteria in marine sediments of cage culture area were investigated in this paper.Results indicate that the proportion of spore-forming bacteria in sediment just below cage is as much as 50% of culturable heterotrophic bacteria.Distant from cage,the proportion of s...
