Opis:
The antimicrobial activity of chloroform and methanol extracts of Lennea coromandelica were screened for their was studied against gram positive bacteria strains Staphylococcus aureus, Streptococcus pyogenes and Bacillus subtilis gram negative bacteria strains Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli and fungal strains such as Candida albicans, C. parapsilosis, C. krusei and C. glabrata using disc diffusion method, determination of Minimum Inhibitory Concentrations (MIC), Minimum Bacterial Concentrations (MBC) and Minimum Fungicidal Concentrations (MFC). The antimicrobial activity for different concentrations like 250 μg, 500 μg and 1000 μg of different solvent extracts of Lannea cormandelica. bacterial strains and recorded in highest mean zones of inhibition ranged from 19.6 mm and Candidal strains and the exhibited the highest mean zones of inhibition ranged from 10.6 mm. Methanol extracts showed the best results as inhibition zones against tested organisms. Results showed also that, the greatest effect was towards Staphylococcus aureus and the lowest was against Candida krusei. The present study reported the great effect of Lannea cormandelica extracts against some of most important pathogens.

Opis:
Increasing concentrations of chromium caused reduction in growth, chlorophyll contents and mineral mutrients of bhendhi. At increasing concentrations of chromium, all the attributes were found to be reduced. Chromium is one of the toxic elements discharging from tannery industry. The long disposal of tannery effluent to the agricultural land causes serious damages in the soil texture; reduce the growth of microorganisms and agricultural crops. Large areas of Vellore district of Tamilnadu was seriously affected by the tannery effluent irrigation to the agricultural land. The present study was conducted to identify the phytotoxic effect and physiological changes of Abelmoschus esculentus (L.) Moench under the treatment of different concentrations of chromium solutions (2.5, 5, 10, 25, 50, 75 and 100 mg/l). The result shows that there was a gradual reduction in the morphological parameters (root length, shoot length, fresh weight and dry weight). Similarly the photosynthetic pigments (Chlorophyll and carotenoid) and biochemical parameters such as protein, amino acid, and sugars were also gradually decreased with increasing concentrations of chromium.
