When Micrococcus strain 12B grown on o-phthalate was incubated with 3-methylphthalate, three compounds accumulated. These were shown to be 2-pyrone-3-methyl-4,6-dicarboxylic acid, 3,4-dihydroxy-6-methylphthalic acid, and 5-hydroxy-3-methyphthalic acid, all previously undescribed. A pathway for the formation of these compounds is proposed.

The antimicrobial activity of five sanitizing agents employed in clean areas designated for the pharmaceutical manufacturing of sterile products was tested against nine microorganisms, including four microorganisms from the clean area microbiota. The method consisted of challenging 5 mL of each sanitizing agent 70% isopropyl alcohol, 0.4% LPH®, 1.16% hydrogen peroxide, 4% hydrogen peroxide, 1% ...

The present study aims to investigate the antimicrobial and antitumor properties of Ganoderma lucidum fruit bodies grown under tropical habitat. The phytochemicals present in Ganoderma sp. DKR1 were analyzed and identified as saponins, tannins, terpenoids and phlobatannins. The bioactive compounds in Ganoderma sp. DKR1 were extracted using the solvents (ethyl acetate and chloroform). Its antimi...

new two nano- sized schiff base complexes [m(l)], where l= 2, 2'-((1e, 1e')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and m=cu or zn, (a, b complexes) were synthesized by ultrasonic irradiation. these complexes were characterized by elemental analysis, molar conductivity, ft-ir, fluorescence emission, 1h nmr, field emission scanning electron sp...

Plant-associated bacteria can have beneficial effects on the growth and health of their host. Nevertheless, the role of endophytic bacteria present in seeds has not been investigated in depth. In this study, the cultivable endophytic population of seeds from Arabidopsis thaliana exposed to 2 μm cadmium for several generations (Cd seeds) was compared with a population isolated from seeds of plan...

Several naphthalene and anthracene degrading bacteria were isolated from rhizosphere of Populus deltoides, which were growing in non-contaminated soil. Among these, four isolates, i.e. Kurthia sp., Micrococcus varians, Deinococcus radiodurans and Bacillus circulans utilized chrysene, benzene, toluene and xylene, in addition to anthracene and naphthalene. Kurthia sp and B. circulans showed posit...

The aim of the present investigation was to assess and compare the antimicrobial activities of the lemon (Citrus sinensis) peel extract and lemon oil against common food borne pathogens and to study their potential as food bio-preservatives. The antagonistic activity of lemon peel extract and lemon oil was studied against common food borne pathogens like Staphylococcus aureus, Staphylococcus ep...

The aim of the present study is to investigate the electrochemical behaviour of orthodontic wires in artificial saliva with and without bacteria. Four factors were considered to characterize the bacteria present in the saliva, viz. urban and rural groups of vegetarians and non-vegetarians. The results showed that among the heterotrophic bacterial isolates, Gram-positive species dominated over t...
