Cadmium, cobalt, iron, lead, and zinc levels were measured in tissues (roots, leaves, and stems) of Azadirachta indica collected at various locations in Akungba-Akoko, Nigeria (Nigeria). The elements’ transfer coefficients into plant tissues were also calculated in order to quantify differences in bioavailability among plant species. The tissues were acid-digested and flame atomic absorption spectrophotometry was used to study them. The following heavy metal amounts (ppm) were found in the plant’s roots, leaves, and stems: Cd (0.14 – 0.34, 0.09 … Continue reading “Accumulation of Heavy Metals in Soil and Their Transfer to Tissues of Azadirachta indica Collected from Akungba-Akoko, Nigeria”

A Recent Study: Effect of Neem Leaf Extract and Neem Oil on Penicillium Growth, Sporulation, Morphology and Ochratoxin A Production

In vitro trials were conducted to evaluate the effect of Azadirachta indica (neem) extracts on mycelial growth, sporulation, morphology and ochratoxin A production by P. verrucosum and P. brevicompactum. Azadirachta indica A. Juss (Meliaceae) (neem plant) extract is one of the most important plant products which inhibit mycotoxin production. The effect of neem oil extract from seeds and leaf was evaluated at 0.125, 0.25 and 0.5% and 6.25 and 12.5 mg/mL, respectively, in Yeast Extract Sucrose (YES) medium. Ochratoxin A … Continue reading “A Recent Study: Effect of Neem Leaf Extract and Neem Oil on Penicillium Growth, Sporulation, Morphology and Ochratoxin A Production”
