Microalgae could become an important resource for addressing increasing global demand for food, energy, and commodities while helping to reduce atmospheric greenhouse gasses. Even though Chlorophytes are generally regarded safe for human consumption, there is still much we do not understand about the metabolic and biochemical potential of microscopic algae. The aim of this study was to evaluate...

Dünya nüfusunun hızla artmasıyla birlikte enerji krizleri, iklim değişiklikleri, küresel ısınma, gıda yetersizliği ve dengesiz beslenme gibi sorunların beraberinde geleceği tahmin edilmektedir. Bu öngörülmesiyle birlikte, insanoğlu alternatif kaynaklarına ihtiyaç duymaya başlamıştır. Yüksek besin içerikleri, sağlığa olumlu etkileri sürdürülebilirlikleri ile ilgi gören algler, fonksiyonel olmaya...

1. Mycosporine-like amino acids (MAAs) are a family of secondary metabolites known to protect organisms exposed to solar UV radiation. We tested their distribution among several planktonic ciliates bearing Chlorella isolated from an oligo-mesotrophic lake in Tyrol, Austria. In order to test the origin of these compounds, the MAAs were assessed by high performance liquid chromatography in both t...

Lampenflora communities of bacteria, cyanobacteria, algae, mosses and lichens colonize illuminated show-caves as a consequence disturbances to the caves? ecological equilibrium. These have unesthetic impacts can cause biodeterioration limestone. A 15% hydrogen peroxide solution was proposed for use an agent safe removal these microorganisms. This study tested effects three different biocides (h...

A fragment of the Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) plastid genome has been sequenced. The genome architecture was compared to that of both a non-photosynthetic relative (Prototheca wickerhamii) and a photosynthetic relative (Chlorella vulgaris). Comparative genomic analysis indicated that Helicosporidium and Prototheca are closely related genera. The analyses also revealed th...

Although single-species laboratory toxicity tests with microalgae are sensitive and highly reproducible, they lack environmental realism. Interactions between algae and their associated bacteria, either in the plankton or in biofilms, may alter algal sensitivity to contaminants, which are not mimicked in laboratory toxicity tests. This study investigated the effects of simple algal-bacterial re...

The experiment was performed to evaluate effect of heavy metals on total phytoplankton load (TPL) using water of Turag River adjacent to Ashulia locating on the north-eastern side of Dhaka city, Bangladesh. Total phytoplankton load comprises of Euglena sp., Borodinella sp., Pediastrum biradiatum, Pinnularia sp., Fragillaria sp., Fragillaria crotonensis, Gloeocapsa sp., Navicula sp., Cynedra sp....

The freshwater microalgae Chlorella sp. and Vulgaris were cultured in a laboratory-scale photobioreactor their growth kinetics total lipid production evaluated. These species grown modified Conway medium, with an 8:16 photoperiod mechanical air ventilation. evaluation time was twenty days, the cell density determined daily using Neubauer chamber by optical spectrophotometry at 685 nm. rate perc...
