Impact assessment of cement industry activities on soil nitrogen-fixing bacteria

Nitrogen fixing bacteria play a vital role in transforming atmospheric nitrogen into inorganic form easily available for plant use. However, environmental pollution due to effluent from industrial activities could accumulate in soil, significantly altering the soil chemical and microbiological characteristics, such as nitrogen fixing bacteria. The effect of cement dust on nitrogen-fixing bacteria is presented […]

Evaluation of the antimicrobial activities of different solvent extracts from the bark of Acacia Stenophylla A. CUNN. EX. BENTH.

The present study was conducted to evaluate the in-vitro antimicrobial activities of crude extracts derived from the bark of Acacia stenophylla by different organic solvents such as N-Hexane, Chloroform, Ethyl acetate, and N-Butanol. These solvent extracted samples were applied against three Gram-positive bacteria including Bacillus atrophaus, Bacillus subtilis, and Staphylococcus aureus, as well as four […]

Phytochemical analysis, antibacterial and antioxidant activities of pomegranate (Punica granatum L.) peel extracts

The pomegranate and their derivative parts are rich source of phytochemicals with multiple beneficial biological effects. This study aims to extract the phenolic compound from pomegranate (Punica granatum L.) peel using methanol and ethanol in order to assess their antioxidant and antibacterial activities. The phenolic compounds and flavonoids content were measured using colorimetric methods. The […]

Phytochemical and comparative biological studies of Baccaurea ramiflora (Lour) extract

The aim of this study was to evaluate the phytochemical and in vitro antioxidant activity along with central nervous system (CNS) depressant, analgesic and anti-inflammatory activities of ethanol extract of Baccaurea ramiflora fruits. Qualitative phytochemical screening confirmed the presence of alkaloid, steroid, saponin, phenolic and flavonoid compounds. Total phenolic and flavonoid content measured by Folin-Ciocalteu […]

Evaluation of MIC, MBC, MFC and anticancer activities of acylated methyl β-D-galactopyranoside esters

A bacterial resistance gained by microorganisms to classical antimicrobials is current challenges. Searching of antimicrobial agents with new structure and mode of action is an essential strategy of research. Therefore, some acylated derivatives of methyl β-D–galactopyranoside were employed as test compounds for in vitro antimicrobial functionality test against five human pathogenic bacteria and two phytopathogenic […]

In vitro antidiabetic, antiobesity and antioxidant activities of selected endemic plants from Mount Mayon and Mount Malinao Albay, Philippines

The present study investigated the in vitro biological activities of the ethanol extracts of thirteen endemic medicinal plants in Albay against diabetes, obesity and as free radical scavenger. Alpha-glucosidase (AG), porcine pancreatic lipase (PPL) inhibition tests and DPPH radical scavenging assay were used to determine the antidiabetic, antiobesity and antioxidant properties of the extracts. Quantitative […]

In-vivo biological investigations of methanolic extract of Himalrandia tetrasperma in animal model

The study in reference was planned to evaluate the anti-inflammatory, antipyretic and antinociceptive activities of methanolic extract of Himalrandia tetrasperma (MEHT), as well as acute toxicity. Anti-inflammatory, antipyretic, antinociceptive and acute toxicity activities were evaluated using mice animal model. Anti-inflammatory activity was investigated using carrageenan-induced edema model of inflammation. Brewer, s yeast induced pyrexia method […]

Phytosynthesis of silver nanoparticles using Tamrixa phylla and biological applications

Due to biocompatibility, antimicrobial activities and other medicinal properties, silver nanoparticles (Ag-NPs) have drawn significant attention for bio-medical applications. The present study focused on eco-friendly synthesis of Ag-NPs using Tamarix aphylla aqueous extract. The synthesized Ag-NPs were characterized by UV-Vis spectrophotometer and their characteristic Surface Plasmon Resonance (SPR) peak was observed at (435nm). Fourier Transform […]

In vitro biological screening of crude extract and different fractions of Mirabilis jalapa

The objectives of the current project were to analyze the phytotoxic, insecticidal and anti-termites activities of MJME (Mirabilis jalapa Methanolic Extract) and it successive solvent fractions. Methanol preparation and its different fractions were utilized to assess the phytotoxic, insecticidal and anti-termites activities of the selected plant. The MJME and its various fractions expressed low to […]

Assessment of the physico-chemical and biological quality of the Okpara dam in Benin

The purpose of this work is to study the macroinvertebrate community and the physico-chemical quality of Okpara dam water, in order to assess the impact of anthropogenic activities. Water sampling and macroinvertebrate sampling were conducted at eight stations along the dam. The organic load in the river and the organization of the macroinvertebrate community have […]
