“…Of the 210 bacterial isolates from the brown alga Laminaria saccharina, 103 inhibited the growth of at least 1 of the pathogens tested (Wiese et al 2009). By contrast, out of 92 isolates from Japanese red algae, only ca one-third of the isolates inhibited the growth of environmental and pathogenic bacteria (Kanagasabhapathy & Nagata 2008). Similarly, a low percentage ($12%) of microbes with antibacterial properties belonging to the α-and γ-proteobacteria were isolated from the green alga Ulva australis and the red alga Delisea pulchra, respectively (Penesyan et al 2009).…”

Mini-review: Inhibition of biofouling by marine microorganisms

Any natural or artificial substratum exposed to seawater is quickly fouled by marine microorganisms and later by macrofouling species. Microfouling organisms on the surface of a substratum form heterogenic biofilms, which are composed of multiple species of heterotrophic bacteria, cyanobacteria, diatoms, protozoa and fungi. Biofilms on artificial structures create serious problems for industries worldwide, with effects including an increase in drag force and metal corrosion as well as a reduction in heat transfer efficiency. Additionally, microorganisms produce chemical compounds that may induce or inhibit settlement and growth of other fouling organisms. Since the last review by the first author on inhibition of biofouling by marine microbes in 2006, significant progress has been made in the field. Several antimicrobial, antialgal and antilarval compounds have been isolated from heterotrophic marine bacteria, cyanobacteria and fungi. Some of these compounds have multiple bioactivities. Microorganisms are able to disrupt biofilms by inhibition of bacterial signalling and production of enzymes that degrade bacterial signals and polymers. Epibiotic microorganisms associated with marine algae and invertebrates have a high antifouling (AF) potential, which can be used to solve biofouling problems in industry. However, more information about the production of AF compounds by marine microorganisms in situ and their mechanisms of action needs to be obtained. This review focuses on the AF activity of marine heterotrophic bacteria, cyanobacteria and fungi and covers publications from 2006 up to the end of 2012.

“…It has been previously reported that individual bacterial strains isolated from epibiotic marine biofilms are capable of inhibiting the growth of S. aureus (Burgess et al 1999;Kanagasabhapathy and Nagata 2008). It has also been shown that individual marine biofilm isolates can be induced to express increased activity against S. aureus when grown in the presence of spent culture media from S. aureus, or in co-culture with S. aureus (Burgess et al 1999;Kanagasabhapathy and Nagata 2008).…”

The study of environmental biofilms is complicated by the difficulty of working with them under lab conditions. Nonetheless, knowledge of cellular activity and interactions within environmental biofilms could lead to novel biomedical applications. To address this problem we previously proposed a new technique for inducing resistance to Staphylococcus aureus in an intact environmental biofilm. In the current follow-up study we applied the new technique in a biogeographically distinct environment using a different strain of S. aureus. The proposed technique for inducing resistance to S. aureus in an environmental biofilm involves growing the environmental biofilms over several days in media reflecting their natural habitat on agar that contains spent culture supernatant from S. aureus over-night culture. We found in this second study that it was possible to induce resistance to S. aureus in an environmental biofilm from a biogeographically distinct environment, though not in the same way as we had previously observed. Environmental consortia from Sydney Harbor, Australia display an ability to inhibit biofilm formation by S. aureus; only in the case where the environmental biofilms were pretreated with UV radiation was there a difference in activity between environmental consortia grown on plain agar, and that grown on S. aureus agar. Application of the new technique in the current study also differs in that significant killing of cells within an established S. aureus biofilm by environmental consortia grown on S. aureus agar was possible.

“…Many silent biosynthetic genes are only activated under specific conditions for the enhance production of antibiotics (Scherlach and Hertweck, 2009). Thus, new cultivation approach, particularly strategies similar to the natural habitats in which microorganisms defending themselves against competitive bacteria can be used to enhance the production of secondary metabolites (Kanagasabhapathy and Nagata, 2007). So, co-culture of microorganisms can be used as an alternative way to screen production antimicrobial drugs.…”

Modulation of antibacterial activity of actinomycetes by co-culture with pathogenic bacteria

In this study, we investigated the effect of pathogenic bacteria on the production of antibiotics by actinomycetes.We used four strains of actinomycetes-ANAM-5, ANAM-39, AIAH-10 and ANTS-1, which were isolated from the soils of Sundrabans, Bangladesh. All the strains were cultured in absence or presence of either alive or heatkilled human pathogens (Staphylococcus aureus and E. coli). The antibacterial activity of cultured cell-free supernatant fluid was analyzed by disc diffusion assay against the inducer strains. Three out of the four marine actinomycetes tested showed enhanced antibacterial activity against Staphylococcus aureus and E. coli. ANAM-5 and AIAH-10 showed enhanced antibacterial activity when co-cultured with Staphylococcus aureus whereas ANAM-5 and ANAM-39 showed enhanced antibacterial activity when co-cultured with E. coli. The highest enhancement of antibacterial activity was exhibited by the strain ANAM-5 against Staphylococcus aureus (from 9 mm to 18 mm inhibition zone). The study has important ecological and biotechnological implications in case of microbial competition in the natural environment and may become helpful to discover novel classes of antibiotics with high specificity and huge production.
