“…Rice hull is the major by-product of milling and represents approximately 20 % of the rough grain weight (Xuan et al 2003). Rice hulls are plentiful at hand and were tested as an environmentally friendly and sustainable source for algicide production (Park et al 2009). Unfortunately, the less abundant rice straw appeared to be more effective and selective towards cyanobacteria than hulls (Jia et al 2014).…”

To help ban the use of general toxic algicides, research efforts are now directed towards the discovery of compounds that are specifically acting as cyanocides. Here, we review the past and look forward into the future, where the less desirable general algicides like copper sulphate, diuron or endothall may become replaced by compounds that show better specificity for cyanobacteria and are biodegradable or transform into non-toxic products after application. For a range of products, we review the activity, the mode of action, effectiveness, durability, toxicity towards non-target species, plus costs involved, and discuss the experience with and prospects for small water volume interventions up to the mitigation of entire lakes; we arrive at recommendations for a series of natural products and extracted organic compounds or derived synthetic homologues with promising cyanocidal properties, and briefly mention emerging nanoparticle applications. Finally, we detail on the recently introduced application of hydrogen peroxide for the selective killing of cyanobacteria in freshwater lakes.

“…However, at the concentrations of WBL of 1.6 and 3.2 g/l, growths of M. aeruginosa NIES-843 were significantly inhibited. Several studies have indicated that some agricultural byproducts such as barley straw (Gibson et al 1990), decomposing rice straw (Park et al 2006) and rice hulls (Park et al 2009), have been shown to have antialgal activities. Rotting barley straw has already been applied to control algal blooms in many reservoirs in UK (Barrett et al 1999), and no deleterious environmental impact was observed in the receiving watercourses (Everall and Lee 1996).…”

“…Several chemical algicides such as CuSO 4 and pesticides have been proposed to control harmful cyanobacterial blooms, but most of these broad toxins are impracticable because of a subsequent secondary pollution. Many natural biomaterials, such as decomposing rice straw (Park et al 2006), rice hulls (Park et al 2009), brown-rotted wood , oak leaves , and especially, barley straw (Gibson et al 1990), have been found to have inhibitory effects on the growth of harmful algal blooms, and thus they have been applied to control algal blooms in some waters such as reservoirs in UK (Barrett et al 1999). In order to explore the inhibitory mechanisms of these algicidal natural biomaterials on harmful algae, intensive studies on identification of inhibiting chemicals from these materials have been conducted.…”

Wheat bran leachate (WBL) has been shown to have an inhibitory effect on Microcystis aeruginosa in this study. In order to explore the inhibitory mechanism of WBL on M. aeruginosa, physiological responses of M. aeruginosa NIES-843 under the WBL stress were studied. The expressions of six important genes related to the D1 protein of photosynthetic processes (psbA), synthesis of microcystins (mcyB), antioxidant protein peroxiredoxin (prx), synthesis of fatty acid (fabZ) and the repair of biological macromolecules (recA, grpE) were studied. Under the WBL stress, no significant change was found in expressions of both grpE and recA, but expressions of psbA, fabZ and prx were shown to be down-regulated, and slight up-regulated expression was found in mcyB. It was shown that oxygen evolution of M. aeruginosa NIES-843 was significantly depressed, and intracellular ATP contents became lower, after exposure to WBL. Similarly, maximum electron transport rates of photosynthetic activities decreased significantly, but intracellular reactive oxygen species levels boosted dramatically under the WBL stress, and cell lysis was observed. Therefore, it is suggested that photosynthetic systems and membranes were the potential targets of toxicity of WBL on M. aeruginosa, and the oxidative damage is an important mechanism explaining the inhibitory effect of WBL on M. aeruginosa.

The effects of culture and extract solutions of six macrophytes on the growth of three common phytoplankton were investigated under laboratory conditions. Culture solutions were taken from a Hoagland nutrient solution that contained live plants growing for 7 days and the extract solution was made from a solution with fresh plant pieces immersed in Hoagland nutrient solution for 48 h. The algae were grown in the culture or extract solution for 15 days and the algal density was determined every 2 days. The results showed that the culture solution of the macrophytes both inhibited and stimulated algae growth depending on the macrophytes and the algae. All extract solutions of the macrophytes exhibited a stimulatory effect on the growth of the algae that also varied with the macrophytes and the phytoplankton. The results indicated that culture solutions of macrophytes may be more suitable for the control of algal blooms in eutrophic waters than their extract solutions.
