Contrasting Methane, Sulfide and Nitrogen‐Loading Regimes in Bioreactors Shape Microbial Communities Originating From Methane‐Rich Coastal Sediment of the Stockholm Archipelago

Environmental Microbiology, Volume 27, Issue 2, February 2025.
In this study, microbial communities are enriched in brackish anoxic bioreactors with methane, sulfide, nitrate and ammonium. Novel diversity is identified and functionally analysed. ABSTRACT Coastal ecosystems are increasingly exposed to high nutrient loads and salinity intrusions due to rising seawater levels.

Engineered small metal‐binding protein tag improves the production of recombinant human growth hormone in the periplasm of Escherichia coli

FEBS Open Bio, 2020
Fusion proteins play an important role in the production of recombinant proteins in Escherichia coli. They are mostly used for cytoplasmic expression since they can be designed to increase the solubility of the target protein, which then can be easily ...

Recent advancements in aquaponics with special emphasis on its sustainability

Journal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract An aquaponic system which is an integration of hydroponics with aquaculture is sustainable, ecologically friendly, and uses non‐renewable resources with very high efficacy. The increasing trend in aquaponics research demonstrates a growing recognition of its potential to address critical global issues such as food security, water conservation,

Nitrite production by ammonia‐oxidizing bacteria mediates chloramine decay and resistance in a mixed‐species community

Microbial Biotechnology, 2020
Summary As water distribution centres increasingly switch to using chloramine to disinfect drinking water, it is of paramount importance to determine the interactions of chloramine with potential biological contaminants, such as bacterial biofilms, that ...

Comparison of Novel and Established Nitrification Inhibitors Relevant to Agriculture on Soil Ammonia- and Nitrite-Oxidizing Isolates

Frontiers in Microbiology, 2020
Nitrification inhibitors (NIs) applied to soil reduce nitrogen fertilizer losses from agro-ecosystems. NIs that are currently registered for use in agriculture appear to selectively inhibit ammonia-oxidizing bacteria (AOB), while their impact on other ...

Removal of ammonia by immobilizaed Nitrosomonas europaea in a biotrickling filter packed with polyurethane foam [PDF]

, 2007
[Abstract] A chemolithoautrotrophic microorganism Nitrosomonas europaea has been utilized to remove gaseous ammonia in a biotrickling filter packed with polyurethane foam. The optimal pH for removing was 7.5 and the biological removal efficiency was zero

Comparative Evaluation of the Zootechnical Performance, Body Composition, Haemato‐Biochemical Profile, and Enzymatic Activity of Nile tilapia (Oreochromis niloticus) Cultured in Biofloc and Conventional Rearing Systems

Aquaculture Research, Volume 2025, Issue 1, 2025.
This study compared the impacts of three aquaculture systems, a biofloc tank system (BTS) without sludge removal, a clear water (non‐biofloc) tank system (CTS), and an earthen pond system (EPS), on the zootechnical, biochemical, haematological, and enzymatic activities of Nile tilapia (Oreochromis niloticus). Monosex (male) fish (initial weight: 22.01 ±
