Advantages, Factors, Obstacles, Potential Solutions, and Recent Advances of Fish Germ Cell Transplantation for Aquaculture—A Practical Review
(MDPI, 2022-02-10)Germ cell transplantation technology enables surrogate offspring production in fish. This technology has been expected to mitigate reproductive barriers, such as long generation time, limited fecundity, and complex broodstock ... -
Altered regulation of the glnA gene in glutamine synthetase mutants of Bacillus subtilis
(American Society for Microbiology, 1986-07-01)Expression of beta-galactosidase by Bacillus subtilis strains carrying transcriptional fusions of the glnA promoter region to the Escherichia coli lacZ gene was found to be regulated by the nitrogen source in glnA+ strains. ... -
Altered regulation of the glnRA operon in a Bacillus subtilis mutant that produces methionine sulfoximine-tolerant glutamine synthetase
(American Society for Microbiology, 1993-02)A Bacillus subfilis mutant that produced glutamine synthetase (GS) with altered sensitivity to DL-methionine sulfoximine was isolated. The mutation, designated glnA33, was due to a T- A-to-C- G transition, changing valine ... -
Anaerobic Ammonia-Oxidizing Bacteria and Related Activity in Baltimore Inner Harbor Sediment
(American Society for Microbiology, 2005-04)The discovery of bacteria capable of anaerobic ammonia oxidation (anammox) has generated interest in understanding the activity, diversity, and distribution of these bacteria in the environment. In this study anammox ... -
Bacterial community analysis of marine recirculating aquaculture system bioreactors for complete nitrogen removal established from a commercial inoculum
(Elsevier, 2019-03-30)An experimental recirculating aquaculture system was constructed under ambient seawater conditions to compare microbial community diversity of nitrifying and denitrifying biofilters that were derived from a commercial ... -
Characterization and abundance of anaerobic ammonia oxidizing (anammox) bacteria in biofilters of recirculating aquaculture systems
(BioMed Central Ltd, 2018-02-10)While biofilters are widely used to metabolize ammonia and other wastes in marine recirculating aquaculture systems, the ammonia-oxidizing bacterial and archaeal communities have not been characterized across a diversity ... -
Chemogenetic Depletion of Hypophysiotropic GnRH Neurons Does Not Affect Fertility in Mature Female Zebrafish
(MDPI, 2022-05-17)The hypophysiotropic gonadotropin-releasing hormone (GnRH) and its neurons are crucial for vertebrate reproduction, primarily in regulating luteinizing hormone (LH) secretion and ovulation. However, in zebrafish, which ... -
Climate and season are associated with prevalence and distribution of trans-hemispheric blue crab reovirus (Callinectes sapidus reovirus 1)
(MEPS, 2020-08-13)Among the many Callinectes spp. across the western Atlantic, the blue crab C. sapidus has the broadest latitudinal distribution, encompassing both tropical and temperate climates. Its life history varies latitudinally, ... -
Current advances in molecular, biochemical, and computational modeling analysis of microalgal triacylglycerol biosynthesis
(Elsevier, 2016-07-14)Triacylglycerols (TAGs) are highly reduced energy storage molecules ideal for biodiesel production. Microalgal TAG biosynthesis has been studied extensively in recent years, both at the molecular level and systems level ... -
Draft Genome Sequence of Marine Bacillus sp. Strain ISO11, a Candidate Finfish and Shellfish Probiotic
(American Society for Microbiology, 2018-10-18)Bacillus sp. strain ISO11, a Bacillus cereus clade member isolated from the intestinal tract of Fundulus heteroclitus, possesses potential probiotic and antibacterial activity against Vibrio sp. pathogens. Antibacterial ... -
Draft Genome Sequence of Shewanella sp. Strain ISO12, a Candidate Probiotic Isolated from the Intestine of Fundulus heteroclitus
(American Society for Microbiology, 2020-05-28)The genome of Shewanella sp. strain ISO12, which was isolated from the intestine of wild-caught Fundulus heteroclitus, was sequenced and is reported here. Bioinformatic analysis revealed genes encoding the bacteriocin ... -
