In this work was investigated the potential of Bacillus subtilis UCP 0146 in the bioconversion of the medium containing 100% of cassava flour wastewater to obtain bioemulsifier. The evaluation of the production was carried out by the emulsification index (IE24) and surface tension (TS). The ionic charge, stability (temperature, salinity and pH measured by IE24 and viscosity), ability to remove and disperse oil and textile dye were investigated. B.subtilis produced an anionic bioemulsifier in the medium containing 100% of cassava wastewater in condition 4 of the factorial design (9% of the inoculum, at 35 °C and agitation of 100 rpm) with surface tension of 39mN/m, IE24 of 95.2 % and yield 2.69 g.L-1. Stability at different pH (2-8), temperatures (0-120ºC) and NaCl, dispersed (55.83 cm2-ODA) and reduced the viscosity of the burned engine oil (90.5 cP) , removed 94.4% petroleum and demonstrated efficiency in methylene blue removal (62.2%). The bioemulsifier and its synthesis from bacteria and also emphases on the role of surfactants in oil remediation.

Pre Treatment

Azo dyes are widely used in textile industry. Unused dyes, consisting mainly non biodegradable released along with waste water streams without any proper pre-treatment which cause nuisance for environment and accumulate in flora as well as fauna. These also exhibit allergic, carcinogenic and mutagenic properties for human beings. Isolation and screening of azo dye degrading bacteria are economic in biodegradation and detoxification. In the present study, 200 waste water samples were collected from dye-contaminated sites of textile industries and bacterial species such as Bacillus subtilis, Pseudomonas aeruginosa and Psuedomonas putida were isolated and identified. Evaluation of decolorizing properties of these bacteriae were done by UV-Vis spectroscopy (Amax 596 nm) in different concentrations using different carbon sources such as Hans’s medium and GYP medium. Maximum decolourisation of 0.1% azo dyes were recorded to be 89.0%, 91% and 86% in Hans medium containing charcoal source by Bacillus subtilis, Pseudomonas aeruginosa and Psuedomonas putida respectively at 24 hrs. These bacterial isolates may be utilized in large scale for pre-treatment for ecological balance by avoiding water pollution.

The ionic charge, stability (temperature, salinity, and pH measured by IE24 and viscosity), and ability to remove and disperse oil and textile dye were investigated. B. subtilis produced an anionic bioemulsifier in the medium containing 100% cassava wastewater under Condition 4 of the factorial design (inoculum 9% at a temperature of 35 °C and shaken at 100 rpm), and showed a surface tension of 39 mN/m, an IE24 of 95.2%, and a yield of 2.69 g·L−1. The bioemulsifier showed stability at different pH (2–8), temperatures (0–120 °C), and NaCl concentrations, a dispersion oil displacement area (ODA) test of 55.83 cm2, and a reduction of the viscosity of the burned engine oil (90.5 Cp). The bioemulsifier was able to remove petroleum (94.4%) and methylene blue azo dye (62.2%). The bioemulsifier and its synthesis from bacteria also emphasizes the role of surfactants in oil remediation.

Bacillus subtilis C3, a commercial textile dye-decolorizing and -degrading bacterium, was isolated from the common effluent treatment plant (CEPT) of the Jetpur textile dyeing and printing industrial sector situated in the district of Rajkot, Gujarat, India. Here, we present the annotated 4.18-Mb draft genome sequence of B. subtilis C3, providing information about the metabolic pathways involved in decolorization and degradation of several commercial textile azo dyes. Thus, we confirm B. subtilis C3 as a potential candidate for bioremediation of textile effluents.

Subtilis Bacteriophage

The protein product of cistron 3 of Bacillus subtilis bacteriophage Ø29 is essential for viral DNA synthesis and is covalently bound to the 5’-termini of the Ø29 DNA. When the DNA-protein complex is cleaved with a restriction endonuclease, the protein is bound to the two terminal fragments. The 28,000 dalton protein can be visualized by electron microscopy as a small dot and often is seen only when two ends are in apposition as in multimers or in glutaraldehyde-fixed aggregates. We sought to improve the visibility of these small proteins by use of antibody labeling.

ZusammenfassungZentrales Bauteil des Genius® 90 Therapie Systems ist der sogenannte Genius-Tank, dem die frische Dialyseflüssigkeit entnommen und in den die verbrauchte Lösung nach der Dialyse zurückgeführt wird. Daher kommt der sicheren Aufbereitung des Systems eine besondere Bedeutung zu. Hierfür wird ein Aufbereitungsverfahren unter Verwendung von UV-Licht in Kombination mit einem chemischen Desinfektionsmittel angewendet. Ziel der hier beschriebenen Untersuchung war es, die Wirkungsbreite und Wirkungstiefe dieses Aufbereitungsverfahrens unter praxisnahen Phase-3-Bedingungen zu ermitteln. Dazu wurde das Gerät mit Mikroorganismen und Viren künstlich kontaminiert und die Wirkung der einzelnen Verfahrensschritte ermittelt. Im Gegensatz zu der üblichen Vorgehensweise praxisnaher Untersuchungen machen Aufbereitungsverfahren medizinischer Geräte unter Phase-3-Kriterien meist eine neuartige Arbeitsweise erforderlich – im Falle der hier vorgestellten Untersuchung sogar die Konstruktion eines speziellen Geräts zur Platzierung von Keimträgen im Genius-Tank. Im Ergebnis konnte gezeigt werden, dass bereits UV-Licht allein sowie in Kombination mit einem chemischen Desinfektionsmittel unter praxisnahen Bedingungen eine sichere Wirksamkeit gegen Bakterien (Pseudomonas aeruginosa) und bakterielle Sporen (Bacillus subtilis), Schimmelpilze (Aspergillus brasiliensis) und Viren (Murines Parvovirus) besitzt.
