s a part of ARPA-E’s MARINER program, a team of scientists and entrepreneurs is pursuing a selective breeding program
to improve the productivity and composition of sugar kelp, Saccharina latissimi, which could serve as feedstock for biofuels.
ARPA-E’s and our goal is to develop tools and a pathway toward low-cost (< $100/DWT) seaweed feedstock that could supply
10% of US transportation fuels. Current markets are human and animal foods. Our project will develop several complementary
tools to reach this objective. To facilitate the high-throughput creation of family crosses, we are developing cell sorting methods to
efficiently isolate and clone gametophytes. USDA/Cornell and others will employ PacBio and Illumina sequencing to create a deep-
sequenced reference genome and establish a variant catalog for our founding populations and families. WHOI, UCONN and contract
farmers will oversee field trials of 144 families (from 12 different ‘strains’) planted in triplicate plots on two farm sites (nearshore
and offshore) over two growing seasons. The resulting family phenotypic data will be associated with genetic markers, and we will
identify variants significantly associated with primary productivity and composition traits. A goal is to develop methods to predict
offspring performance based upon genotype and breeding values of parents as a shortcut around extensive and expensive field testing.
A separate ARPA-E project will test the potential labor-saving use of WHOI’s autonomous underwater vehicles and sensors for
conducting nutrient, acoustic, and optic measurements of macroalgae plots. These will be compared to conventional hands-on field
measurements. Ultimately our goal is to develop sugar kelp with the improved composition for use as a bioenergy feedstock.
