Abstract: The accumulation of pesticides in the environment poses a major health concern to humans, plants and animals, thus the presence of these toxicants require close monitoring. Bioindicators such as green algae are widely researched for the detection of toxicants or pollutants and has been reported to have more advantages compared to the conventional detection methods. The objective of this study is to determine the response of carotenoids and chlorophyll in Spirogyra as a potential bioindicator in pesticides detection. Cells immobilized using agarose gel were exposed to 0.001 mg/L, 0.010 mg/L, 0.100 mg/L, 1.000 mg/L and 10.000 mg/L of 2,4-dichlorophenoacetic acid (2, 4-D) and atrazine for a period of 48 hours. Respond trends for chlorophyll and carotenoids were recorded. Carotenoids showed higher potential as the marker for 2,4-D detection while chlorophyll was the better one in atrazine detection

Abstract: Antibiotic resistance in clinically important bacteria is an increasing problem worldwide. Alternative therapeutic agents such as medicinal plants should be sourced to overcome this problem. Acne is a common skin disorders in many people and can have a debilitating effect on the self-esteem and confidence of an individual. Staphylococcus aureus and Staphylococcus epidermidis. The aim of this study was to determine if crude plant extracts from medicinal plants could be used as a suitable alternative to antibiotics for the treatment of acne. Crude extracts were obtained from three medicinal plants: Plectrantus amboinicus, Azadirachta indica and Murraya koenigii using an ethanol extraction method. The extracts were tested individually and in combination against two common causative agents of acne: Staphylococcus aureus and Staphylococcus epidermidis. The antimicrobial activity was indicated by the zone of inhibition obtained in the disk diffusion assay. All the plant extracts exhibited an
