[0135] 2g of zirconium beads were mixed with 1.1ml of dispersion masterbatch. To this dispersion mixture was added 0.2 g of TGA sample. Pigment dispersions were prepared using a Biospec 3110Bx Mini beadbeater by bead beating at 42R speed for 3 minutes (30 second intervals, 1 minute off). Tubes were incubated at room temperature for 15 minutes to cool. 150L for particle size determination using a grinding gauge. 250 uL was used to draw down the Leneta ink test strips. The scraped sample was dried for 24 hours, and then L, a, b measurements were performed by 3nH using a YD 5050 spectrodensitometer.

Abstract

The disclosed method and related systems and devices relate to producing a pigment from microbial biomass. The pigment may be an engineered black pigment. The method may include a thermal processing step where the microbial biomass is charred. The biomass in the charred and pre-charred state can be washed chemically and / or mechanically. In another step biomass is ground via a grinding of milling process. The grinding / milling may occur at any various points in the process. In some embodiments the biomass has a particle size between 0. and 100 microns.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 62 / 756 / 968, filed November 7, 2018, entitled "BIOLOGICALINKS AND COATINGS AND ASSOCIATED METHODS, SYSTEMS AND DEVICES," which Incorporated herein in its entirety by reference. technical field [0003] The disclosed technology generally relates to the production of pigments and colorants from microbial biomass. Background technique [0004] Pigments and colorants represent a more than $30 billion annual industry. However, the production of these compositions is associated with the production of toxic biological products that may harm human health and the environment. Previous attempts to produce pigments from nontoxic biomass have been limited in their ability to produce particle sizes small enough for most industrial applications. Therefore, there is a need in the art for a method of producing pigments / colorants from sustain...
