Production and characteristics of bioflocculant TPT-1 from a consortium of Bacillus pumilus JX860616 and Alcaligenes faecalis HCB2

The combination of microorganisms in consortia enhances high bioflocculant yields. The study aimed at producing and characterising bioflocculant from Bacillus pumilus JX860616 and Alcaligenes faecalis HCB2. Bioflocculant TPT-1 was obtained through ethanol extraction after optimum conditions were established. The characteristics of the bioflocculant TPT-1 were obtained by scanning electron microscope equipped with...

Occurrence and susceptibility patterns of Campylobacter isolated from environmental water sources

Environmental waters are established sources of Campylobacter infections in humans. The aim of this study was to assess the distribution and susceptibility profiles of Campylobacter species isolated from irrigation and domestic water sources in Ghana. Samples were pre-enriched with CCDA broth and isolated on mCCDA agar. Isolates were confirmed on API CAMPY kit and with the Kirby-Bauer disk diffusion method to determine...

Fungi toxic efficiency of some plant volatile essential oils against plant pathogenic fungi

Plant essential oils have the potential to replace the synthetic fungicides in the management of different fungal diseases. Four different essential oils of eucalyptus (Eucalyptus globulus), citronella (Cymbopogon citrate), karanj (Pongamia pinnata) and neem (Azadirachta indica) were selected because of their high inhibitory activities against ten phytopathogenic fungi. The antifungal screening for all the four Eos...

Bacteria associated with sugarcane in Northeastern Brazil

Sugarcane has a high demand in nitrogen, increasing costs and causing damages to the environment. It is necessary to find alternatives to reduce nitrogen fertilizers use. Diazotrophic bacteria have capacity to promote growth in grass with potential to fix N2 and solubilize inorganic phosphate. This study aimed to evaluate bacterial community associated with different sugarcane varieties in Northeastern Brazil, select...
