Abstract: The present invention is directed to a system and method for producing a vitamin B12 enriched Duckweed Bacterial Culture (DBC) composition. The present invention further discloses a composition comprising a vitamin B12 enriched DBC, wherein said composition comprises at least one Lemnoideae species and at least one vitamin B12 producing bacteria species, further wherein said vitamin B12 content in said composition is in the range of between about 0.01 and about 100 ?g per 100 g of said DBC.

Abstract: The present invention discloses a system for cultivating surface-growing floating aquatic plants, in particular, duckweeks or lemnoideae species, on a non horizontally positioned sheet-like substrate. The aforementioned system comprises (a) a predetermined volume of growth media flowing through sheet-like substrate provided with a predetermined inoculum of said aquatic plants; (b) at least one sheet-like substrate; (c) an irrigation mechanism configured to a top down irrigation flow in said sheet-like substrate; and (d) a regulation mechanism configured to control said irrigation flow. The present invention further discloses methods for cultivating the aforementioned aquatic plants.

Abstract: The present invention is directed to a biocompatible and biodegradable natural disperse dye for dyeing polyester fabrics which is dispersed in water and derived from green plants. The disperse dye contains as the active dye compound an acid bewchlorophyllin derivative such as acid form Mg-chlorophyllin or acid form Cu-chlorophyllin. The disperse dye of the present invention can be used for the dyeing of polyester fabrics by traditional methods in concentrations ranging from 0.01% to 20% on weight of fibers (OWF), thus providing a dyed fabric with good color strength and good fastness to light, washing and rubbing, under conditions of dye exhaustion of greater than 90%.

Abstract: The present invention is directed to a system and method for producing vitamin B12 enriched Duckweed Bacterial Culture (DBC) composition. The aforementioned method comprises steps of inoculating at least one Lemnoideae species and at least one vitamin B12 producing bacteria species in a volume of growth media; incubating said at least one Lemnoideae species and said at least one vitamin B12 producing bacteria species under predetermined conditions to provide a Duckweed-Bacterial Culture (DBC); determining time intervals within said plots characterized by DBC with highest vitamin B12 content; and harvesting said DBC at said predetermined time intervals, thereby providing vitamin B12 enriched DBC composition.

Abstract: The present invention discloses a malleable mass of dough comprising: (a) dry material; said dry material comprises flour; and, (b) a liquid component; wherein said liquid component originates from fresh whole Wolffia genus plant added to said dry material during process of kneading; said flour to said fresh Wolffia plant weight ratio (w/w) is in the rage of 100:47 to 100:88; further wherein said dough has a consistency of 500+/?15 FU or [10-170 kPa].
