Abstract The capability of Yersinia ruckeri to survive in the aquatic systems reflects its adaptation (most importantly through the alteration of membrane permeability) to the unfavorable environments. The nonspecific porins are a key factor contributing to the permeability. Here we studied the influence ...
Aeromonas veronii is a kind of opportunistic pathogen to fish and humans, significantly impending aquaculture production. Recently, we isolated two A. veronii strains, named GYC1 and GYC2, from diseased Gibel carp (Carassiusgibelio) in China. Based on gyrB (DNA gyrase B subunit) genes of GYC1 and GYC2, ...
Sulfides and volatile organic sulfur compounds (VOSc) in water are not only malodorous but also toxic to humans and aquatic organisms. They cause serious deterioration in the ecological environment and pollute drinking water sources. In the present study, a source water reservoir—Zhoucun Reservoir in ...
Klebsiella pneumoniae is an opportunistic pathogen that is responsible for causing nosocomial and community-acquired infections. Despite its common presence in soil and aquatic environments, the virulence potential of K. pneumoniae isolates of environmental origin is largely unknown. Hence, in this ...
Background Inbreeding is often associated with a decrease in offspring fitness (‘inbreeding depression’). Moreover, it is generally assumed that the negative effects of inbreeding are exacerbated in stressful environments. This G × E interaction has been explored in many taxa under different environmental ...
Background Brown algae are promising feedstocks for biofuel production with inherent advantages of no structural lignin, high growth rate, and no competition for land and fresh water. However, it is difficult for one microorganism to convert all components of brown algae with different oxidoreduction ...
In this study, three typical members representative of different arginine metabolic pathways were firstly identified from Apostichopus japonicus, including nitric oxide synthase (NOS), arginase, and agmatinase. Spatial expression analysis revealed that the AjNOS transcript presented negative expression ...
A laboratory-scale microwave (MW) unit was applied to treat fresh blackwater sludge that represented fecal sludge (FS) produced at heavily used toilet facilities. The sludge was exposed to MW irradiation at different power levels and for various durations. Variables such as sludge volume and pathogen ...
With long industry chain and high-tech, the marine energy industry covers various professional areas, it is a strategic emerging industry. The industry chain of marine energy is composed of upstream, midstream and downstream. By reviewing the literature, defining concepts and sorting the basic theories, ...
This paper presents the development of a bio-inspired swimming robot from concept design to simulation for marine aquaculture applications. Based on investigation of several fish motions, the Manta ray is found to be the most suitable mock object since the flapping pectoral fin features long-endurance, ...
HF radar wave data are obtained through an iterative inversion procedure that provides an estimate of the directional spectrum, from which waveheight, period and direction parameters can be derived. The critical data quality requirements for the backscatter spectra, in order to generate reliable wave ...
Marine oil spill is an inevitable and undesirable consequence of producing and transporting petroleum, as well as the associated refined products. To reduce oil spill pollution, China has made many great achievements to develop adequate pollution contingency plans for several years. During the oil spill ...
China has carried out five massive investigation and selection work on tidal energy and the latest survey results show that China's theoretical potentiality of the tidal energy within 10m depth contour offshore is estimated to be 192.86 GW. 171 potetial sites that have over 500 kW installed capacity ...
This work presents an autonomous system for marine integrated physical-chemical and biological monitoring - the MarinEye system. It comprises a set of sensors providing diverse and relevant information for oceanic environment characterization and marine biology studies. It is constituted by a physical-chemical ...
Brominated flame retardants (BFRs) are ubiquitous industrial chemicals likely to persistently exist in the environment, bioaccumulate in food chains, and even may cause adverse health effects in human. Borgundfjorden fjord system, an important spawning ground for the Norwegian coastal cod (Gadus morhua) ...
Chaetoceros is one of the largest marine genus of phytoplankton and plays an important role in ocean ecosystem and global climate. Automatic segmentation of Chaetoceros is a challenging task due to the species' biomorphic characteristics. In this paper, we present a novel method using pixel-wise classification ...
On the background of the compilation of a new round MFZ(marine functional zoning) in Tangshan, this paper take the method of integrating onsite survey and remote sensing survey, comprehensively considers the status quo of marine development and utilization, marine natural environment, social needs, ...
Intensive cultures of shrimps produce more than 10 individuals per square meters with the use of hatchery reared post-larvae and the supply of compounded diets. The paddle wheel aerators are usually installed in the pond to supply oxygen and collect the sludge generated from the excretion of shrimps ...
We examined characteristics of material transport and a tidal front formation in a semi-enclosed bay, Korea, based on numerical experiment results. Pollutant diffusion resulted in a relatively high concentration in the northwest part of the bay compared to the other area, because of inactive flow and ...
The ocean and the Blue Economy are increasingly top priorities worldwide. The immense ocean territory in the planet and its huge associated economical potential is envisioned to increase the activity at the ocean in the forthcoming years. The support of these activities, and the convergence to the Internet ...
