Growth promotion of Chlorella ellipsoidea by co-inoculation with Brevundimonas sp. isolated from the microalga (2008, background): “Croft et al. (2005) reported that exogenous cobalamin (vitamin B12) is required by 171 of 326 algal species that they surveyed, indicating that cobalamin auxotrophs are widespread among algae.”
Allelochemicals produced by Caribbean macroalgae and cyanobacteria have species-specific effects on reef coral microorganisms (2011, background): “Corals also may rely on microbial symbionts for nutritional requirements and efficient adaptation to environmental change (Shashar et al. 1994; Ducklow and Mitchell 1979; Lesser et al. 2004; Croft et al. 2005).”
A chronicle of a killer alga in the west: ecology, assessment, and management of Prymnesium parvum blooms (2015, background): “It is important to note here that sometimes mixotrophic algae can be dependent on phagocytizing bacteria as a means of obtaining essential vitamins (Croft et al., 2005, 2006), in which case a positive association between bacteria and the mixotrophic alga would be anticipated.”
Screening and selection of growth-promoting bacteria for Dunaliella cultures (2013, background): “Yet, we did not record any microalgal μmax improvement, demonstrating that synthesis of growth-promoting compounds [11–13] by bacteria did not occure or was not efficient.”
Dynamics of Dissolved Organic Phosphorus (2015, background): “…bacteria may effectively exchange utilizable organic matter for vitamin B12, thereby maintaining a viable population of B12-requiring phytoplankton during periods of vitamin deficient growth (Croft et al., 2005; Haines and Guillard, 1974), as might occur in low nutrient, subtropical gyres.”
Transformation of iodate to iodide in marine phytoplankton driven by cell senescence (2010, background): “The role of bacteria Many phytoplankton cultures are often only available with their associated bacteria; diatoms in particular require the associated bacteria for normal growth (Fukami et al. 1997, Croft et al. 2005, Grossart & Simon 2007).”
Algae-bacteria interactions: Evolution, ecology and emerging applications. (2016, background): “Studies show micro-nutrients like Vitamins (Croft et al., 2005; Kuo and Lin, 2013; Teplitski and Rajamani, 2011), macronutrients like nitrogen and carbon (Bolch et al., 2011; Kazamia et al., 2012b; Kim et al., 2014a; Teplitski and Rajamani, 2011) and phytohormones (Teplitski and Rajamani, 2011) usua”
Algae as nutritional and functional food sources: revisiting our understanding (2016, positive): “Cobalamin is not required or synthesized by higher plants (Croft et al. 2005) so fruits and vegetables are poor sources of vitamin B 12 , which explains why vitamin B 12 -deficiency is common among people following strict vegetarian or vegan diets (Haddad et al. 1999; Waldmann et al. 2004; Allen…”
Interactions between Diatoms and Bacteria (2012, background): “They found that about 52% of the surveyed heterokonts were not able to grow in B12-deficient medium, indicating the importance of the vitamin to diatoms (39).”
Chemical interactions between marine macroalgae and bacteria (2010, background): “In turn, bacteria mineralize organic substrate, supplying the algae with carbon dioxide, minerals and growth factors (Croft et al. 2005, 2006).”
The effect of vitamin B12 on phytoplankton growth and community structure in the Gulf of Alaska (2011, background): “Because bacteria are a primary source of vitamin B12 (Croft et al. 2005), vitamin limitation in cold, polar latitudes may be due to slow vitamin production rates, as the degree to which phytoplankton were limited by vitamins in the Southern Ocean was inversely proportional to in situ bacterial…”
Algae as an important environment for bacteria – phylogenetic relationships among new bacterial species isolated from algae (2013, background): “Several specific associations between algae and bacteria have been described (i.e. Biegala et al. 2002; Croft et al. 2005; Dimitrieva et al. 2006; Grossart & Simon 2007; Amin et al. 2009; Gärdes et al. 2010; Wagner-Döbler et al. 2010; Hollants et al. 2011; Seyedsayamdost et al. 2011; Trias et al.…”
