The sheath rot rice disease is known to be associated Pseudomonas fuscovaginae and a recent study on the symptomatic of revealed that this bacterial pathogen abundant in highland ecology cultivation Burundi. From asymptomatic samples rice, collection isolates culturable microbiome have been carried out. A comparison between total was made. Phenotypic assays vitro were performed after identifica...

The primary goal of this study was to isolate hydrocarbon-degrading organisms and assess their ability to bioremediate petroleum-contaminated soil and water. Nigeria is one of the major oil producing countries and petroleum contamination is widespread in agricultural soil. Alcaligenes sp. strain 3k was isolated from a kerosene-polluted soil in Ilorin, Nigeria. We also assessed its ability to de...

separated by an intervening stretch of DNA, variable in length depending on the particular species of origin (Curtis & Hazelkorn, 1983; Shinozaki & Sugiura, 1983). The gene from S,.rzc~c.lioc.oc~r~us PCC30 1 (Reichelt & Delaney, 1983) has been cloned into the ampr region of PLa2311 (Remaut ct al., 1981) with expression controlled by the strong temperature-sensitive leftward promoter (PI ) of ba...

Microbiological impedance devices are routinely used by food and manufacturing industries, and public health agencies to measure microbiological growth. Factors contributing to increases and decreases in capacitance at the culture medium-electrode interface are poorly understood. To objectively evaluate the effects of temperature, cell density and medium conductivity on capacitance, admittance ...

In this study, a novel betaproteobacterium, strain DPN7(T), was isolated under mesophilic conditions from compost because of its capacity to utilize the organic disulfide 3,3'-dithiodipropionic acid. Analysis of the 16S rRNA gene sequence of strain DPN7(T) revealed 98.5 % similarity to that of Tetrathiobacter kashmirensis LMG 22695(T). Values for sequence similarity to members of the genera Alc...

The treatment of the industrial wastewater can be particularly difficult in the presence of toxic compounds. Excessive concentration of Chromium in soluble form is toxic to a wide variety of living organisms. Biological removal of heavy metals using natural and genetically engineered microorganisms has aroused great interest because of its lower impact on the environment. Ralston metallidurans,...

Azithromycin and clarithromycin were paired with other antibiotics to test synergistic activity against 300 multidrug-resistant pathogens isolated from cystic fibrosis (CF) patients. Clarithromycin-tobramycin was most active against Pseudomonas aeruginosa and inhibited 58% of strains. Azithromycin-trimethoprim-sulfamethoxazole, azithromycin-ceftazidime, and azithromycin-doxycycline or azithromy...

Alcaligenes xylosoxydans protected pigeonpea from Fusarium wilt in a pot experiment and field trials. When seeds of pigeonpea (C. cajan) were treated with A. xylosoxydans and sown in soil infested with Fusarium, the incidence of wilt was reduced by 43.5% and resulted in 58% higher grain yield. The antifungal activity of A. xylosoxydans was based on chitinase production and was comparable in eff...
