Abstract: Provided are methods, devices, and systems for measuring aquatic biomass in an aqueous liquid, optionally for the cultivation, growth optimization, and harvest of an aquatic biomass for plant protein production. In particular, measurements of aquatic biomass density are based on light absorption of the aquatic biomass. The aquatic biomass includes an aquatic organism such as Lemna, including Lemna minor. The plant protein isolates include a RuBisCO protein.

Abstract: Disclosed herein are mutant photosynthetic microorgnaisms having an attenuated SGI1 gene. The mutants have reduced chlorophyll and increased productivity with respect to wild type cells. Also disclosed are methods of using such mutants for producing biomass or bioproducts, and methods of screening for such mutants.

Abstract: The invention involves mutant or recombinant Chlorophyte algal organisms that have a genetic modification in a gene encoding a chloroplastic signal recognition particle 43 (cpSRP43). In one embodiment the Chlorophyte organisms are Trebouxiophyte algae that are diploid or polyploid for a gene encoding a chloroplastic signal recognition particle 43 (cpSRP43). The mutant organisms can have a genetic modification in one allele of the gene but not in another allele of the gene. The mutant or algal organisms have higher biomass and lipid productivity. Additional mutant or algal organisms are disclosed that also have a genetic modification to one or more genes encoding a light harvesting chlorophyll a/b (binding) protein.
