The recently developed Zurich Ice Nucleation Chamber (ZINC) was used to explore ice nucleation of size-selected mineral dust particles at temperatures between −20C and −55C. Four different mineral dust species have been tested: montmorillonite, kaolinite, illite and Arizona test dust (ATD). The selected particle diameters are 100 nm, 200 nm, 400 nm and 800 nm. Relative humidities with respect t...

The Pseudomonas aeruginosa GSM3 isolated from dye contaminated soil was able to degrade Reactive Violet 5 completely as a sole source of carbon (300 mgL) within 20 h under static condition. The organism exhibited good decolorization ability in the pH ranges from 5.0 to 9.0 and temperature from 30 to 40C respectively. The optimum degradation was observed at 37C and pH 7. The maximum concentratio...

A nutritional requirement for the lipase production by Pseudomonas aeruginosa strain was investigated. The bacterial strain was isolated from municipal sewage and it was culture with different nutritional composition. The maximum lipase activity was obtained with maltose as the sole carbon source 6.5 Uml, followed by lactose 4.6Uml . The various salts used the best results were observed with ca...

Background: Plant foods, as functional provide not only the essential nutrients needed to sustain life but also low-energy foods for health promotion and disease prevention, burger, made of several types meat, contains soy oats in varying proportions enhance its chemical physical properties, well test efficacy oat flour fat alternatives.Objective: The goal this study was conduct analyses Calcul...

It is aimed to determine the positive and quality of Sea Snail (Rapana venosa) process. The samples examined in research are determined after introduction (Rapanoza) boiling, washing, selection snail meat content shell, temperature, 24 final freezing at -35 -40C whether will be passed through glass-18zene before suffocating from shock. After a week, total six stage were stored freezer – 80 °C. ...
