SUMMARY
Measurements were made of growth, pigmentation, photosynthesis, respiration, quinone Hill reaction, cell morphology, and structure as a function of growth light intensity for various algae. These processes showed varying degrees of dependency upon light intensity and are discussed with reference to algal classification. Eighteen algae, examples from 10 taxonomic divisions, were studied.read more

Adaptation of unicellular algae to irradiance: an analysis of strategies
TL;DR: Comparison of the photon flux densities at which photoinhibition occurs in dinoflagellates and diatoms suggests that the former often experiencephotoinhibition at comparatively low irradiances, and this tolerance of a large absolute range of photon fluxdensities may, in part, explain why di atoms are often associated with spring blooms.
Journal ArticleDOI
Thermophilic blue-green algae and the thermal environment.
TL;DR: The results show clear trends in growth and survival at Suboptimal Temperatures and in Rates of Growth, Photosynthesis, and Respiration in Culture.
Journal ArticleDOI
The assumptions and rationales of a computer model of phytoplankton population dynamics1
TL;DR: The model simulates population dynamics and gross physiology of phytoplankton species in the epilimnion of a lake where algal growth is subject to temperature, light, and nutrient constraints and includes luxury consumption, end-product inhibition of both carbon fixation and nutrient uptake, and species-specific differential efficiencies of nutrient assimilation.

Algae for biofuels and energy
TL;DR: This book covers the key steps in the production of renewable biofuels from microalgae - strain selection, culture systems, inorganic carbon utilisation, lipid metabolism and quality, hydrogen production, genetic engineering, biomass harvesting, extraction.

The vertical and seasonal distribution of chlorophyll in lakes of the Experimental Lakes Area, northwestern Ontario: Implications for primary production estimates
TL;DR: An in vivo flow-through fluorometer system revealed narrow bands of very high chlorophyll concentrations in the meta- or hypolimnia of all clear, stratified ELA lakes as mentioned in this paper.

Studies of marine planktonic diatoms: i. cyclotella nana hustedt, and detonula confervacea (cleve) gran.
TL;DR: Bacteria-free clones of the small centric diatom Cyclotella nana Hustedt were isolated, three from estuarine localities, one from Continental Shelf waters, and one from the Sargasso Sea as mentioned in this paper.

Studies with Cyanidium caldarium, an anomalously pigmented chlorophyte.
TL;DR: Cyanidium caldarium, an alga found in acid hot springs troughout the world, has a morphology and developmental history resembling those of Chlorella, but contains C-phycocyanin and no chlorophyll other thanchlorophyll a.

A Sugar‐Containing Basal Medium for Vitamin B12‐Assay with Euglena; Application to Body Fluids*
TL;DR: The z strain of Euglena gracilis, which grows more vigorously than the bacillaris strain previously used, is recommended and allows the distinction between “combined” and “uncomb combined” B12 in serum.
Journal ArticleDOI
Photosynthetic characteristics of some freshwater plankton diatoms in relation to underwater radiation
TL;DR: Photosynethtic behaviour of the diatoms, recorded from exposures at varying depths in the English Lakes, is analysed in terms of the photosynthetic characteristics of the species and the environmental conditions of underwater radiation and temperature.
