Micellar complexes were prepared from bacteriochlorophyll a and bacteriopheophytin a with the cationic detergents, cetyltrimethyl ammonium bromide and cetylpyridinium chloride. These complexes have spectroscopic properties (absorption, circular dichroism) which are very different from the ones formed with non-ionic detergents like Triton X-100, and also with anionic detergents. Bacteriochloroph...

I t has been demonstra ted tha t in the green leaf chlorophyll is combined with protein by t rue chemical linkage. The chlorophyll-protein compound of the spinach leaf is insoluble in water and buffer solutions, bu t can be dispersed by detergents yielding bri l l iantly clear solutions. In addition to clarifying these solutions, the detergents denature the protein and change the absorption spe...

The action of synthetic detergents upon several strains of bacteriophage has been mentioned in a previous communication (Klein et al., 1945). With the exception of gamma coli phage, the bacteriophages tested were highly susceptible to the germicidal activity of the various test compounds. The gamma phage, on the other hand, proved to be resistant to the highest concentrations of the detergents ...

Enzymes are important molecules that help chemical reactions in living beings happen faster and easier. Did you know enzymes present many products used our daily lives? detergents, pets’ food own food. Sponges live the oceans need from enzymes, too. Microscopic organisms make their homes on marine sponges, these microbial partners produce sponges with nutrient digestion! These useful can also b...

The molecular mechanism of the solubilisation of phospholipid bilayers by nonionic detergents was studied by turbidity changes, carboxyfluorescein fluorescence dequenching, steady-state and time-resolved fluorescence anisotropy of DPH, lifetime measurements, ANS binding and 31P-NMR. Particular attention has been paid to the effective detergent-to-lipid ratio in the lipid phase. The disturbance ...

One of the most significant urban services is carwash, which generates large amounts wastewater containing a variety pollutants, including sand, gravel, suspended solids, surfactants, oil products, diesel cleaners, etc., that may cause environmental pollution when transferred to sewage system without any treatment. The effective treatment crucial prevent as well recycle water source. Contaminan...

Abstract The discharge of laundry wastewater (LWW) into rivers contaminates the water and exposes it to harmful chemicals present in detergents fabric softeners. This draws attention need implement treatment for LWW. study focused on determining ability ceramic tiles remove total phosphorus (TP) chemical oxygen demand (COD) from commercial coarse aggregate tile waste (CTW) was used as adsorbent...
