Article Abstract

The enumeration and evaluation of the activity of marine bacteria are important in the food industry. However, detection of marine bacteria in seawater or seafood has not been easy. The Petrifilm aerobic count plate (ACP) is a ready-to-use alternative to the traditional enumeration media used for bacteria associated with food. The purpose of this study was to evaluate the usefulness of a simple detection and enumeration method utilizing the Petrifilm ACP for enumeration of aerobic marine bacteria from seawater and an edible seaweed, Caulerpa lentillifera. The efficiency of enumeration of total aerobic marine bacteria on Petrifilm ACP was compared with that using the spread plate method on marine agar with 80 seawater and 64 C. lentillifera samples. With sterile seawater as the diluent, a close correlation was observed between the method utilizing Petrifilm ACP and that utilizing the conventional marine agar (r=0.98 for seawater and 0.91 for C. lentillifera). The Petrifilm ACP method was simpler and less time-consuming than the conventional method. These results indicate that Petrifilm ACP is a suitable alternative to conventional marine agar for enumeration of marine microorganisms in seawater and C. lentillifera samples.

Southern right whales (Eubalaena australis) are mysticete cetaceans commonly observed in the coastal waters of Brazil, particularly in Santa Catarina State. There is limited understanding of the causes of calf mortality in this species, particularly concerning infectious diseases. We report a case of omphalophlebitis caused by Streptococcus equi subsp.

Antibiotic resistance genes (ARGs) have escalated to levels of concern worldwide as emerging environmental pollutants. Increasing evidence suggests that non-antibiotic antimicrobial substances expedite the spread of ARGs. However, the drivers and mechanisms involved in the generation and spread of ARGs in the atmosphere remain inadequately elucidated.

As a global challenge, marine biofouling is causing serious economic losses and adverse ecological impacts. In recent years, a variety of promising and environmentally friendly anti-fouling strategies have emerged, among which the excellent anti-fouling performance of bionic autocrine coatings has been recognized. However, bionic autocrine coatings still suffer from uncontrollable secretion behavior, poor mechanical stability, and poor abrasion resistance.

Phosphorus (P) is pivotal for all organisms, yet its availability is, particularly in the marine habitat, limited. Natural, puff-shaped colonies of Trichodesmium, a genus of diazotrophic cyanobacteria abundant in the Red Sea, have been demonstrated to capture and centre dust particles. While this particle mining strategy is considered to help evade nutrient limitation, details behind the mechanism remain elusive.

Marine bacteria play important roles in the degradation and recycling of algal polysaccharides. However, the marine bacteria involved in fucoidan degradation and their degradation pathways remain poorly understood. Here, we report the complete genome sequence of Isoptericola halotolerans SM2308, isolated from a brown algal sample collected from an intertidal zone of the Yellow Sea in China.
