“…In the treatments F and H with very low glucose concentration (37.5 and 150 mol C L −1 ), glucose may have become a competitive factor between the attached bacteria and the bacterial mixture. Under C-limitation, the bacterial mixture may release chemical substances that have a bactericidal or bacteriostatic impact on other microbial populations, such as the attached bacteria, and this can alter inter-population relationships by influencing the outcome of competition for available nutrient and energy supply (Fredrickson and Stephanopoulos, 1981;Lemos et al, 1991;Pybus et al, 1994;Tokunaga et al, 1996). The inhibition of growth of the attached bacteria may also reduce the growth of M. aeruginosa.…”

a b s t r a c tTo investigate the interaction between cyanobacteria and heterotrophic bacteria under gradients of glucose and nitrate, a cyanobacterial strain of Microcystis aeruginosa was grown in microcosms with and without a freshwater bacterial mixture, which was collected from Lake Taihu. Concentrations of glucose (1350, 975, 600, 300, 150, and 37.5 mol C L −1 ) and nitrate (150, 300, and 9000 mol N L −1 ) were used in a range of combinations giving 9 different treatments of glucose:nitrate. In the microcosm without the bacterial mixture, M. aeruginosa abundance gradually increased with days in all treatments. However, M. aeruginosa had much lower density in some treatments with the bacterial mixture. The difference in M. aeruginosa growth could be explained by competition with bacteria in the cultures in which these were added. The abundance of M. aeruginosa and bacteria when grown together was nearly equal and the number of the bacterial species was highest in the treatment with 300 mol C L −1 and 150 mol N L −1 . Our results suggest that at this glucose:nitrate ratio M. aeruginosa and the bacterial mixture maintain a balance, and bacteria maintain diversity. In conclusion, we propose that dissolved organic carbon and nitrate availability fundamentally affects the structure as well as stoichiometry of pelagic associations.

“…YL-02632S Tokunaga et al, 1996), Pseudomonas batumici (Smirnov et al, 2000), and P. fluorescens (Mattheus et al, 2010) produce polyketides kalimantacin/batumin that are bacteriocidal for Staphylococcus aureus. Zou et al (2007) reported that A. faecalis MHS033 and MHS013 produces fungistatic VOCs, such as methanamine, 1-butanamine, and/or benzaldehyde.…”

IntroductionCyclamen (Cyclamen persicum Miller) is a popular plant for horticulture, and for many years, sales of seeds and saplings have benefited the economy of the Ena-Nakatsugawa district, Gifu Prefecture, Japan. This success can be attributed, in part, to the close attention that gardeners pay to diseases affecting the production of seeds and saplings. Several diseases of cyclamen are caused by fungi and bacteria, such as anthracnose (Colletotrichum gloeosporioides), bacterial bud blight (Pseudomonas marginalis pv. marginalis), fusarium wilt (Fusarium oxysporum Schlechtendahl f. sp. cyclaminis), gray mold (Botrytis cinerea), bacterial soft rot (Erwinia carotovora subsp. carotovora), and bacterial leaf blight (Pantoea agglomerans) (Database of Plant Diseases in Japan, NIAS GenBank, https://www.gene.affrc.go.jp/databases-micro_pl_dis-eases_en.php). In particular, anthracnose and bacterial leaf blight frequently occur in Gifu.Among several bacterial species with fungicidal activity, Bacillus subtilis is well characterized (Weller, 1988). Most fungicidal B. subtilis secrete iturin group compounds, which consist of linear alkyl fatty acids and circular depsipeptides, including D-amino acids, as a highly active fungicidal component (Maget-Dana
