Azo dyes are used as coloring agent in textile industries at larger scale. As a result, large quantity of dye-enriched waste water is generated which subsequently poses environmental problems. Biological tool involving bacteria having azoreductase enzyme has proved to be more effective and efficient in dye effluent treatment. Current work focuses on Staphylococcus caprae (S. caprae) for degradation and decolorization of Reactive Red-195 (RR-195) azo dye. For this purpose, factors such as pH, temperature, inoculums, carbon and nitrogen sources, and dye concentrations have been optimized for maximum decolorization and degradation. S. caprae (4 mg/mL) efficiently resulted into 90% decolorization of RR-195 dye under static condition at 100 μg/mL concentration, 30 °C and pH 7.0 at a 12-h contact period. FTIR analysis has revealed the formation of new functional groups in the treated dye such as O-H stretch at 3370 cm-1, C-H band stretching at 2928 cm-1, and new band at 1608 cm-1 which specify the degradation of aromatic ring, 1382 and 1118 cm-1 represents desulfonated peaks. Biodegraded metabolites of RR-195 dye such as phenol, 3, 5-di-tert-butylphenol, and phthalic acid have been identified respectively that find industrial applications. Phytotoxicity test has shown non-toxic effects of treated dye on germination of Vigna radiata and Triticum aestivum seeds. Further, antibiotic diffusion assay has confirmed the biosafety of S. caprae.

Oddělení kardiovaskulární rehabilitace se specializují na rehabilitaci nemocných po kardiochirurgickém výkonu nebo po akutním infarktu myokardu. Nemocniční infekce jsou velmi častou a závažnou komplikací prováděné léčby. V posledních dvou desetiletích se nicméně ukázalo, že hlavní příčinou případů infekce a sepse na jednotkách kardiologické péče jsou koaguláza-negativní stafylokoky (CoNS), mezi nimiž významné místo zaujímá bakterie Staphylococcus capitis. Popisujeme naše zkušenosti z izoláty S. capitis od pacienta, který byl hospitalizován s kardiovaskulárním onemocněním a s bércovými vředy.
Cardiology Rehabilitation wards specialize in the rehabilitation of patients who are suffering from cardiac surgery or an acute heart attack. Hospital infections are the most frequent and severe complication of health- care. Nevertheless, during the last two decades, coagulase-negative staphylococci (CoNS) have been indicated as the primary cause of infections and septicemia in cardiology care units. Among the CoNS, the role played by Staphylococcus capitis in the field of infectious processes has been considered. We present our experience of S. capitis isolations from a patient admitted with cardiovascular disease with lower limbal diabetic ulcers.
