Microbial Siderophore: A State of Art

Siderophore Production by Microorganisms Isolated From a Podzol Soil Profile

“…We used glucose broth medium for cultivation the microorganisms in order to estimate the siderophores production since it has recently been shown that using glucose as carbon source in the culture medium could enhance the siderophore production compared to other carbon sources such as lactose and maltose (Santos et al, 2014). On the other hand, it was found that the effect of the carbon source on the siderophore production differ according to the type of the microorganisms (Chincholkar et al, 2007). For instance, the addition of amino acids (glycine, aspartic acid and glutamic acid) to the culture medium increased the siderophore production by fungi, while the medium containing glucose could enhance the siderophore production by bacteria (Chincholkar et al, 2007).…”

However, other earlier studies found that the use of succinate as a carbon source increased the siderophore yields compared to glycerol (Chodat and Gouda, 1961;Meyer and Abdallah, 1978;Rachid and Ahmed, 2005).…”

Challenges of climate change

“…62 PGPR's also secrete Siderophores, in response to iron deficiency, which help in the transportation of ferric iron into plant cells from insoluble forms. They also improve antagonism against phytopathogens 63 and in induction of systemic resistance in plants. 64 Sharaf-Eldin et al 65 studied the effect of Bacillus subtilis FZB24 on saffron corms under ex vitro conditions in Egypt and reported that inoculation of B. subtilis FZB24 significantly increased leaf length, flowers per corm, weight of the first flower stigma, total stigma biomass, and significantly decreased the time required for corms to sprout and the number of shoots.…”

Alkaliphilic bacteria: applications in industrial biotechnology

“…Siderophores have been suggested to have potential applicability in therapeutics, agriculture, and environment [47]. Biofilms, composed of bacterial aggregates, can cause problems for human health and industry [233], leading to economic losses.…”
