Molecular Phylogenetic Analysis of Nitrobacter spp. [PDF]

open access: yesInternational Journal of Systematic Bacteriology, 1994
The phylogeny of bacteria belonging to the genus Nitrobacter was investigated by sequencing the whole 16S rRNA gene. The average level of similarity for the three Nitrobacter strains examined was high (99.2%), and the similarity level between Nitrobacter winogradskyi and Nitrobacter sp. strain LL, which represent two different genomic species, was even

Enhanced Phosphorus Removal From Municipal Wastewater via Cotreatment of Mine Drainage During Primary Clarification. [PDF]

open access: yesWater Environ Res
Cotreating acid mine drainage with municipal wastewater in existing WWTPs can enhance phosphorus and BOD removal without compromising treatment performance. The approach offers a cost‐effective, infrastructure‐efficient solution that leverages existing plant capacity while decreasing nutrient loads and supporting environmental goals in mining regions ...

Short Communication: Biochemistry Analysis and Molecular Approach to Identify the Cultured Bacterial from Ex-Tin Mining Lakes

open access: yesJurnal Ilmu Lingkungan, 2022
There are two methods to identify the bacterial characteristic, namely biochemical analysis and the 16S ribosomal ribonucleic acid gene (16S rRNA) sequencing analysis.

The Morphology of Nitrobacter winogradskyi [PDF]

open access: yesJournal of General Microbiology, 1959
SUMMARY: The recently isolated organism of the second phase of nitrification is identified as Nitrobacter winogradskyi Buch. The organism reproduces by polar budding and possesses a distinct and easily demonstrated nucleus. The life cycle includes alternation of motile and non-motile stages.

Icosahedral inclusions (carboxysomes) of Nitrobacter agilis [PDF]

open access: yesJournal of Bacteriology, 1977
The icosahedral bodies of Nitrobacter agilis are about 120 nm in diameter and, as viewed by electron microscopy, consist of an outer shell enclosing 10-nm particles. The inner 10-nm particle is the enzyme D-ribulose 1,5-bisphosphate carboxylase. The bodies isolated from cells incubated 1 month without nitrite had a specific activity for the enzyme of 0.

Response of Nitrifier and Denitrifier Abundance to Salinity Gradients in Agricultural Soils at the Yellow River Estuary

open access: yesAgronomy, 2022
Salinization is considered a threat to agricultural soil and decreases crop yield worldwide. Nitrification and denitrification are the core processes of soil N-cycle.

Experimental study on nitrification in a submerged aerated biofilter [PDF]

open access: yes, 2004
The aim of the present work was to evaluate the performance of a semi-pilot scale BAF in order to obtain a highly polished effluent in terms of removal of organic matter, suspended solids and ammonia and to observe the influence of temperature, pH and ...

Utilization of Nitrosomonas sp and Nitrobacter sp probiotic towards total suspended solid and ammonia level in nile tilapia culturing using aquaponic system

open access: yes, 2021
Nile tilapia (Oreochromis niloticus) is an aquaculture commodity which has high production and tendency to be cultured in intensive culturing system. However, the latter can accumulate high amount of organic waste (leftover feed and fish feces) which ...

Utilization of Nitrosomonas sp. and Nitrobacter sp. probiotic towards nitrite and nitrate level in nile tilapia (Oreochromis niloticus) using aquaponic system

open access: yes, 2021
Based on KKP data, nile tilapia production is highly increasing from 2015 – 2018. To generate high production of nile tilapia, intensive culture system is needed.

Nitrite-Oxidizing Bacteria Community Composition and Diversity Are Influenced by Fertilizer Regimes, but Are Independent of the Soil Aggregate in Acidic Subtropical Red Soil

open access: yesFrontiers in Microbiology, 2018
Nitrification is the two-step aerobic oxidation of ammonia to nitrate via nitrite in the nitrogen-cycle on earth. However, very limited information is available on how fertilizer regimes affect the distribution of nitrite oxidizers, which are involved in
