A certain wastewater treatment plant uses aerobic bacteria, anaerobic bacteria and archaebacteria during secondary treatment of sewage. Unfortunately, during a bad bluzard the sludge digester froze, killing the microbes inside. What is likely to result? a) Floc levels will diminish b) Solid material will not be effectively fitered out c) Methane production will go down d) Floc will not be effectivelyftered out

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
