“…These bacteria live in biologically competitive environments and produce fascinating and structurally complex natural products, which were endowed with special biological activities [ 2 , 3 ]. These compounds are known to mediate interactions in the respective ecosystems, such as predator-prey interactions, or the prevention of fouling [ 4 , 5 , 6 , 7 ].…”

Cyclopropane-Containing Fatty Acids from the Marine Bacterium Labrenzia sp. 011 with Antimicrobial and GPR84 Activity

Bacteria of the family Rhodobacteraceae are widespread in marine environments and known to colonize surfaces, such as those of e.g., oysters and shells. The marine bacterium Labrenzia sp. 011 is here investigated and it was found to produce two cyclopropane-containing medium-chain fatty acids (1, 2), which inhibit the growth of a range of bacteria and fungi, most effectively that of a causative agent of Roseovarius oyster disease (ROD), Pseudoroseovarius crassostreae DSM 16950. Additionally, compound 2 acts as a potent partial, β-arrestin-biased agonist at the medium-chain fatty acid-activated orphan G-protein coupled receptor GPR84, which is highly expressed on immune cells. The genome of Labrenzia sp. 011 was sequenced and bioinformatically compared with those of other Labrenzia spp. This analysis revealed several cyclopropane fatty acid synthases (CFAS) conserved in all Labrenzia strains analyzed and a putative gene cluster encoding for two distinct CFASs is proposed as the biosynthetic origin of 1 and 2.

“…Dixson et al, 2014; Stanley et al, 2012), offering exciting opportunities to promote ecosystem resilience and recovery through use of cues that promote settlement behaviours. Studies are starting to identify chemical compounds that influence larval behaviours (DeBose, Lema, & Nevitt, 2008; De Nys et al, 1995; Dixson et al, 2014; Dreanno et al, 2006; Ganapiriya, Maharajan, & Kumarasamy, 2012; Rittschof, 2000), and larvae appear able to obtain detailed information, such as the likely direction of origin, concentration and degree of degradation from an olfactory cue (Atema, 1995, 1996; Chivers, Dixson, White, McCormick, & Ferrari, 2013; Finelli, Pentcheff, Zimmer, & Wethey, 2000; Weissburg & Zimmer-Faust, 1993, 1994). Together these studies raise the possibility of artificially synthesizing these cues to promote recruitment to degraded habitats.…”

Using insights from animal behaviour and behavioural ecology to inform marine conservation initiatives

The impacts of human activities on the natural world are becoming increasingly apparent, with rapid development and exploitation occurring at the expense of habitat quality and biodiversity. Declines are especially concerning in the oceans, which hold intrinsic value due to their biological uniqueness as well as their substantial sociological and economic importance. Here, we review the literature and investigate whether incorporation of knowledge from the fields of animal behaviour and behavioural ecology may improve the effectiveness of conservation initiatives in marine systems. In particular, we consider (1) how knowledge of larval behaviour and ecology may be used to inform the design of marine protected areas, (2) how protecting species that hold specific ecological niches may be of particular importance for maximizing the preservation of biodiversity, (3) how current harvesting techniques may be inadvertently skewing the behavioural phenotypes of stock populations and whether changes to current practices may lessen this skew and reinforce population persistence, and (4) how understanding the behavioural and physiological responses of species to a changing environment may provide essential insights into areas of particular vulnerability for prioritized conservation attention. The complex nature of conservation programmes inherently results in interdisciplinary responses, and the incorporation of knowledge from the fields of animal behaviour and behavioural ecology may increase our ability to stem the loss of biodiversity in marine environments.

“…Naturally bioactive chemical compounds produced by bacteria and diatoms can cause disruption in biofilm formation ( Ganapiriya, Maharajan & Kumarasamy, 2012 ); therefore, they can be useful in development of environmentally friendly compounds for protection against marine bio-fouling ( Holmström & Kjelleberg, 1999 ) . It is just a matter of finding the correct naturally bioactive compound for a specific application.…”

“…In this perspective, studies concerning marine micro-organisms’ epibiotic chemical defense in the control of biofouling show great promise. Efforts in these areas have proven that the wide range of marine organisms such as algae, sponges, gorgonians, bryozoans, and ascidians are a potential source of anti-fouling metabolites ( Ganapiriya, Maharajan & Kumarasamy, 2012 ; Zhang et al, 2014 ). However, not much detail is known to date regarding anti-biofouling/anti-biofilm natural compounds from marine microorganisms.…”

Natural products from the unique environments of sea water and oceans represent a largely unfamiliar source for isolation of new microbes, which are potent producers of secondary bioactive metabolites. These unique life-forms from the marine ecosphere have served as an important source of drugs since ancient times and still offer a valuable resource for novel findings by providing remedial treatments. Therefore, it can be expected that many naturally bioactive marine microbial compounds with novel structures and bioactivities against those from terrestrial environments may be found among marine metabolites. Biofilms in aquatic environment possess serious problems to naval forces and oceanic industries around the globe. Current anti-biofilm or anti-biofouling technology is based on the use of toxic substances that can be harmful to their surrounding natural locales. Comprehensive research has been done to examine the bioactive potential of marine microbes. Results are remarkably varied and dynamic, but there is an urgent need for bioactive compounds with environmentally friendly or “green” chemical activities. Marine microbes have the potential as upcoming and promising source of non-toxic compounds with sustainable anti-biofouling/anti-biofilm properties as they can produce substances that can inhibit not only the chemical components required for biofilm production but also the attachment, microorganism growth, and/or cell–cell communication.
