The paper examines biodiversity of diatoms in artificial reservoirs the Kalmius river basin, as well degree impact industrial enterprises on water resources by bioindication. author has established current state balance rivers, and use industry Donbass. Thus, is formed due to a part inflow from Seversky Donetsk basin waters main River basin. Agriculture total consume 77% entire region, which an...

The present study describes the complete development of all life cycle stages of Cryptosporidium andersoni in the HCT-8 cell line. The in vitro cultivation protocols were the same as those used for the successful growth of all life cycle stages of Cryptosporidium parvum (Int. J. Parasitol. 31 (2001) 1048). Under these culture conditions, C. andersoni grew and proliferated rapidly with the compl...

Experiments were carried out for the propagation and rearing of Macrobrachium nipponense its feeding on algae, with aim determining density, survival, growth larvae in vitro. Hatched zoae reared at a density 50 zoea/L algae mixture: Chlorella vulgaris, Scenedesmus sp., Pediastrium Microctinium Navicula Ulothrix Cyclotella Daitoma sp. three concentrations 0.5=A, 1.0=B, 1.5=C x 10⁵ cell/ml, survi...

This study was carried out from December 2018 to November 2019 examine the distribution and abundance of harmful algal species (HAS) in central Bonny estuary. Seven sampling stations were established with ArcGIS tool. Microalgae sampled 20 mm mesh plankton net. Nutrients analyzed laboratory using APHA 4500 Method, while physicochemical characteristics determined situ. Results revealed that envi...

Hyriopsis cumingii has attracted attention because of its pearl production performance and water purification capacity. Realizing sustainable industrialized culture H. or applying it to bivalve biomanipulation for controlling eutrophication needs urgent studies about the selection suitable algae effects different microalgae on mussel physiology. To contrast molecular biochemical high-quality mi...

Capsaicin has been extensively studied for its excellent antifouling activity and very low environmental toxicity. However, mixing natural capsaicin with coatings can cause rapid leakage, severely shortening cycle. In this study, we describe the preparation performance of a new capsaicin-modified marine organofluorosilicone, which is based on silicone fluorine acrylate monomers covalently bound...

Monounsaturated fatty acids and their oxidation products were quantified in surficial sediments (0–1 cm) dominated by sympagic (ice-associated) material released at the end of ice melt collected summer central eastern Baffin Bay during 2016 GreenEdge campaign. Sympagic algae preservation towards bacterial mineralization was monitored based on intact oxidized C16:1ω7 (palmitoleic) acid, C18:1ω7 ...
