The Journal of general physiology, 33(4), 349-362 (1950-03-01)

A crystalline enzyme capable of digesting thymus nucleic acid (desoxyribonucleic acid) has been isolated from fresh beef pancreas. The enzyme called "desoxyribonuclease" is a protein of the albumin type. Its molecular weight is about 60,000 and its isoelectric point is

Influence of diatomite addition on membrane fouling and performance in a submerged membrane bioreactor.

Xiao-Li Yang et al.

Bioresource technology, 101(23), 9178-9184 (2010-08-06)

This paper examined the effect of diatomite addition on membrane fouling and process performance in an anoxic/oxic submerged membrane bioreactor (A/O MBR). Particle size distribution, molecular weight distribution and microbial activity have been investigated to characterize the sludge mixed liquor.

Turning the volume down on heavy metals using tuned diatomite. A review of diatomite and modified diatomite for the extraction of heavy metals from water.

Angela F Danil de Namor et al.

Journal of hazardous materials, 241-242, 14-31 (2012-10-16)

Contamination of water by heavy metals is a global problem, to which an inexpensive and simple solution is required. Within this context the unique properties of diatomite and its abundance in many regions of the world have led to the
