Isolation and Characterization of the Lipid Reserve Bodies, Spherosomes, from Layers of Wheat

Rice bran was found to effectively adsorb pesticides in artificial gastric fluid. Equilibrium adsorption isotherms conformed to the Freundlich type (loglog linear). Pretilachlor and esprocarb were successfully removed in artificial gastric fluid with an average removal efficiency of 85.5% and 95.8%, respectively after 90 min when rice bran (10 g/l) was added to samples containing from 0.05 to 5 mg/l of pesticides. The removal of pesticides by rice bran was attributed to the uptake by intracellular particles called spherosomes.

Efficiency of Rice Bran for Removal of Pretilachlor and Esprocarb in Artificial Gastric Fluid

“…They are organelles rich in lipid, and they differ in morphology and origin from large oil bodies. 14) Table 4 shows the removal efficiency of benzene by spherosomes isolated from 0.5-3.0 g (dry weight basis) of the tea or coffee lees; that efficiency increased in response to spherosome amount. We previously reported that the number of spherosomes in lees materials increased with the removal efficiency of organochlorine compounds and benzene by these materials.…”

Use of Tea or Coffee Lees as Adsorbent for Removal of Benzene from Wastewater

et al. 2008

The object of this work was to investigate several adsorbents to determine their effective removal of benzene from wastewater. Tea and coffee lees were found to effectively adsorb benzene. Equilibrium adsorption isotherms conformed to the Freundlich isotherm (log-log linear). Adsorption of benzene by tea or coffee lees was observed in the pH range of 1 to 11. At equilibrium, the adsorption efficiency of tea or coffee lees for benzene was lower than that of activated carbon. The removal of benzene by tea or coffee lees was attributed to the uptake by intracellular particles called spherosomes. Ninety minutes after application of lees to wastewater (pH 10) containing 0.1 g/l of benzene, 75 to 82% of the benzene had been removed.

“…Spherosomes isolated from wheat aleurone have also been reported to have a neutral lipid content of 86.9%, 8.5% phospholipids, and 1.8% protein. 17) Adans and Novellie 18) reported that spherosomes from linseed have an average composition of 27% protein, 12% phosphorus, and 8.6% metals. Their protein value is similar to our spherosomes (Table 1).…”

Effects of Spherosomes on Degradation of Pretilachlor and Esprocarb in Soil

et al. 2007

The fate of pretilachlor and esprocarb in soil with or without spherosomes was investigated for 71 days. The estimated half-lives of pretilachlor in nonsterile soil with and without spherosomes were calculated to be 35.6 and 54.3 days, respectively, while those of esprocarb in nonsterile soil with and without spherosomes were 35.5 and 44.8 days, respectively. The degradation of these pesticides appeared to be essentially due to the biological activity of the soil. Spherosomes should enhance the rate of pretilachlor and esprocarb destruction.
