Inhibit plant growth

This study aimed to quantify the phenolic contents and the antioxidant capacities of leaf extract powders from three Myrtaceae plants, namely Cleistocalyx operculatus (Vietnamese name: Vối), Psidium guajava (Ổi), and Rhodomyrtus tomentosa (Sim), investigate their inhibitive activities on the growth of bacteria isolated from spoiled shrimps, and evaluate their values as preservative agents in the cold storage of Pacific whiteleg shrimps (Penaeus vannamei).

In this study, methanolic extracts from the stems, leaves and flowers of Ipomoea pes-caprae that were collected in Xuan Thuy National Park were evaluated for their antibacterial and antioxidative activities, and their ability to inhibit plant growth. The DPPH free radical scavenging activity of crude methanol extracts was evaluated.

The main objective of this study was to confirm and estimate the algal inhibiting effects of the ethanol and ethyl acetate E. fortunei extracts at concentrations of 500 mg.L- in some natural water samples collected from Hoan Kiem and Lang Lakes. The results of this work may be useful for controlling the toxic cyanobacterium bloom in natural aquatic ecosystem.

The present study was envisaged with the objective to isolate indigenous chromate tolerant bacteria from effluents and their subsequent utilization for chromium uptake or reduction. Samples were collected from two different Common Effluent Treatment Plants (CETPs), located in Ludhiana (sample 1) and Jalandhar (sample 2). In both the samples, chromium was found to be the dominant metal contaminant. A total of 10 morphologically distinct isolates were tested for their tolerance to chromium in terms of minimum inhibitory concentration (MIC) of Cr required for complete inhibition of growth.
