BACTERIOLOGICAL PROPERTIES OF MARINE WATER IN ADRIATIC FISH FARMS: ENUMERATION OF HETEROTROPHIC BACTERIA [PDF]

open access: yesCroatian Journal of Fisheries, 2012
Aquaculture is currently one of the fastest growing food production sectors in the world. Increase in nutrients and organic wastes lead to general deterioration of water quality.

Effects of Copper Availability on the Physiology of Marine Heterotrophic Bacteria

open access: yesFrontiers in Marine Science, 2019
Marine heterotrophic bacteria play a crucial role in the cycling of energy and nutrients in the ocean. Copper (Cu) belongs to the repertoire of essential trace nutrients for bacterial growth, yet physiological responses of marine heterotrophic bacteria ...

Construction of Heterotrophic Axenic System of Chlorella sorokiniana Based on Antibiotic Sensitivity

open access: yesShipin gongye ke-ji, 2023
To construct a heterotrophic axenic system of Chlorella sorokiniana FZU60, the symbiotic bacteria were isolated and identified, and the effects of eight common antibiotics (cefotaxime, kanamycin, neomycin, ampicillin, streptomycin, tetracycline ...

Viability of Heterotrophic Bacteria in Freshwater [PDF]

open access: yesMicrobiology, 1982
SUMMARY: The viabilities of planktonic bacteria from nine freshwaters and one raw sewage were compared. Viabilities estimated from microcolony formation in slide culture (18·4-48·7%) were higher than a conventional plate count method (1·8--14·9%). Microcolony viability was estimated in four ways; the one recommended was the ratio of the microcolony ...

Picocyanobacteria and deep-ocean fluorescent dissolved organic matter share similar optical properties [PDF]

open access: yes, 2017
Marine chromophoric dissolved organic matter (CDOM) and its related fluorescent components (FDOM), which are widely distributed but highly photobleached in the surface ocean, are critical in regulating light attenuation in the ocean. However, the origins

Optimization of carbon and energy utilization through differential translational efficiency. [PDF]

open access: yes, 2018
Control of translation is vital to all species. Here we employ a multi-omics approach to decipher condition-dependent translational regulation in the model acetogen Clostridium ljungdahlii.

Prevalence of heterotrophic methylmercury detoxifying bacteria across oceanic regions [PDF]

open access: yesEnvironmental Science & Technology, 2021
ABSTRACTMicrobial reduction of inorganic divalent mercury (Hg2+) and methylmercury (MeHg) demethylation is performed by themeroperon, specifically bymerAandmerBgenes respectively, but little is known about the mercury tolerance capacity of marine microorganisms and its prevalence in the global ocean. Here, we explored the distribution of these genes in

Microbial metabolism of transparent exopolymer particles during the summer months along a eutrophic estuary system

open access: yesFrontiers in Microbiology, 2015
This study explores the role of transparent exopolymer particles (TEP) as an additional carbon source for heterotrophic microbial activity in the eutrophic Qishon estuary.

Microcystin-LR does not induce alterations to transcriptomic or metabolomic profiles of a model heterotrophic bacterium. [PDF]

open access: yesPLoS ONE, 2017
Microcystins are secondary metabolites produced by several freshwater, bloom-forming cyanobacterial species. Microcystin-producing cyanobacteria co-occur with a complex community of heterotrophic bacteria.

Biodegradation of 17α-ethinylestradiol by heterotrophic bacteria

open access: yesEnvironmental Pollution, 2013
The presence of the synthetic estrogen 17α-ethinylestradiol (EE2) in the environment is of increasing concern due to the endocrine disruption of aquatic organisms. Incomplete removal from wastewater (WW) is one of the main sources of EE2 in aquatic ecosystems, thus improving processes like biological WW treatment/activated sludge (AS) is becoming ...
