Pacific Herring, Clupea pallasi, spawning population assessment for San Francisco Bay, 1992-93 [PDF]
, 1997 We conducted hydroacoustic surveys, spawn surveys, and sampled schools and fishery landings from 8 November 1992 through 18 March 1993 to assess the status of San Francisco Bay's Pacific herring spawning population.

Sustainable levulinic acid production from inulin via hydrothermal conversion
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study investigates the hydrothermal conversion of inulin using potassium pyrosulfate to levulinic acid (LA). The Box–Behnken design approach was applied to optimize the conversion parameters and analyze the interactions influencing LA yield.

Investing in Our Future: The Economic Case for Rebuilding Mid-Atlantic Fish Populations [PDF]
, 2009 Estimates the potential direct economic benefits of rebuilding depleted fish populations in the mid-Atlantic by comparing status quo management scenarios with scenarios in which four fish populations would have been rebuilt by ...

Biotechnology and Bioengineering, EarlyView.ABSTRACT Yeast sugar transporters have highly evolved for preferential glucose transport, a significant roadblock for utilizing non‐glucose sugars in renewable feedstocks such as lignocellulosic biomass. To enable simultaneous transport of multiple sugars, native hexose transporters were replaced by SWEET7p from Arabidopsis thaliana in engineered ...

An approach to estimate the natural mortality rate in fish stocks [PDF]
, 2003 A simple approach is introduced to estimate the natural mortality rate (M) of fish stocks. The approach is based on the age at maximum cohort biomass, or critical length (L*) concept.

Genetically Programmed Control of Overflow Metabolism
Biotechnology and Bioengineering, EarlyView.ABSTRACT Overflow metabolism is a highly undesirable phenomenon that occurs in virtually all cell factories. Although several schemes have been applied to avoid overflow metabolism, this problem remains far from being solved. In this study, a genetic sensor for detecting overflow metabolism was designed, and its substrate specificity and reversibility ...

Raman Spectroscopy–Based Glucose Feed Control Automates Malic Acid Fermentation
Biotechnology and Bioengineering, EarlyView.Raman spectroscopy enables automated, closed‐loop glucose feeding for malic acid production with Ustilago trichophora. Online PLS regression of glucose and malic acid provides input for PID control to maintain 20 g/L glucose. The feed is dynamically adjusted and stopped in response to metabolic demand and product inhibition, demonstrating practical ...

Stock assessment of protogynous fish: evaluating measures of spawning biomass used to estimate biological reference points [PDF]
, 2008 In stock assessments, recruitment is typically modeled as a function of females only. For protogynous stocks, however, disproportionate fishing on males increases the possibility of reduced fertilization rates.

Biotechnology and Bioengineering, EarlyView.ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.

Proceedings of the sixth international coral reef symposium [PDF]
, 1988 On a total of 363 bottoms longline sets in the SW lagoon of New Caledonia, 45 were surveyed using visual census. Abundance and biomass estimates were derived from these censuses.
