NATURAL BIODEGRADATION OF COPROSTANOL IN AN EXPERIMENTAL SYSTEM OF THREE ENVIRONMENTAL CONDITIONS OF JAKARTA WATERS, INDONESIA [PDF]

, 2004
Constraint of using bio-indicator (coliform bacteria) as an indicator of domestic (sewage) pollution in the environment with high environmental stress encourages the discovering of other alternate indicators.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The Investigation of Bioindicator Bacteria in the Supralittoral Zone Sands and Seawater in the Sea of Marmara, İstanbul Province

Aquatic Sciences and Engineering
Investigation of the presence of bioindicator bacteria in the seas is important in terms of detecting bacteriological marine pollution due to human activities and as an indicator of the possible presence of pathogenic bacteria in the environment.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Use of microbial fecal indicator monitoring and fecal source tracking as a park management tool in Rocky Mountain National Park

Environmental Challenges, 2022
Visitation to national parks in the United States increased by an estimated 9,304,786 visitors from 2018 to 2019. This increased visitation has resulted in negative impacts to protected natural resources.

Survival and detection of Bacteroides spp., prospective indicator bacteria [PDF]

Applied and Environmental Microbiology, 1985
Preliminary experiments were performed to assess the use of intestinal Bacteroides spp. as indicators of fecal contamination of water. Viable counts of Bacteroides fragilis, an anaerobic bacterium, declined more rapidly than those of Escherichia coli and Streptococcus faecalis. However, a fluorescent antiserum prepared against B.

Quantitative assessment of the removal of indicator bacteria in full-scale treatment plants

, 2004
The elimination of thermotolerant coliforms (Coli44) and spores of sulphite-reducing clostridia (SSRC) in full-scale water treatment was determined by large volume sampling.
