There are 246 strains of aerobic marine bacteria and 206 strains of anaerobic marine bacteria. Among them gram-positive aerobic bacteria include twelve species Streptococcus parasanguinis intermedius Corynebacterium pseudotuberculosis Bacillus megaterium Staphylococcus vitulinus Leifsonia aquatic Staphylococcus kloosii Alloiococcus otitidis Lysinibacillus sphaericus Staphylococcus hominis Tetragenococcus solitaries Bacillus subtilis Helcococcus kunzii. Gram-negative aerobic bacteria strains include five species Misc. Gram negative Bacilli Elizabethkingia meningoseptica Weeksella virosa Bergeyella zoohelcum Weeksella virosa Bergeyella zoohelcum Chryseobacterium indologenes Empedobacter brevis. Marine anaerobic bacteria strains include 08 species Leptotrichia buccalis Bacteroides capillosus Leptotrichia buccalis Fusobacterium necrophorum Clostridium perfringens Clostridium sordellii Propionibacterium propionicum Prevotella buccae.
