Metals and linear alkylbenzene sulphonate as inhibitors of the algae Pseudokirchneriella subcapitata acid phosphatase activity

Toxicity Assessment of Expired Pesticides to Green Algae Pseudokirchneriella subcapitata

In order to investigate the effect of expired pesticides on the yield and growth rate of green algae Pseudokirchneriella subcapitata, a study was conducted as per the Organisation for Economic Cooperation and Development (OECD) guideline number 201. Fifteen expired pesticide formulations, most commonly used in Indian agriculture, were tested in comparison with their unexpired counterparts. The ...

Effects of a complex mixture of therapeutic drugs on unicellular algae Pseudokirchneriella subcapitata.

Pharmaceutically-active compounds are regularly and widely released into the aquatic environment in an unaltered form or as metabolites. So far, little is known about their potential detrimental effects on algae populations which can ultimately impact nutrient cycling and oxygen balance. For our analysis, the common microalga Pseudokirchneriella subcapitata (P. subcapitata) was exposed to a mix...

Differences in the effects of metals on growth of two freshwater green algae (Pseudokirchneriella subcapitata (Korshikov) Hindak and Gonium pectorale Müller).

Optimization of a Microplate-Based Assay to Assess Esterase Activity in the Alga Pseudokirchneriella subcapitata

The present work describes the optimization of a short-term assay, based on the inhibition of the esterase activity of the alga Pseudokirchneriella subcapitata, in a microplate format. The optimization of the staining procedure showed that the incubation of the algal cells with 20 μmolL fluorescein diacetate (FDA) for 40 min allowed discrimination between metabolic active and inactive cells. Th...
