Use Of Selection Pressures To Enable Microbial Biosynthesis Of Polyhydroxyalkanoates From Anaerobic Degradation Products

View page
US Patent:
8030021, Oct 4, 2011
Filed:
Jun 24, 2009
Appl. No.:
12/456988
Inventors:
Craig S. Criddle - Redwood City CA, US
Allison J. Pieja - Menlo Park CA, US
Assignee:
The Board of Trustees of the Leland Standford Junior University - Palo Alto CA
International Classification:
C12P 39/00
C12P 7/64
US Classification:
435 42, 435135, 435170
Abstract:
A method for inexpensive and efficient PHA biosynthesis includes operating a sequencing bioreactor in alternating phases of nutrient deprivation and carbon feedstock deprivation to select for robust PHA-producing microbes. Preferably, the bioreactor is operated in a non-sterile manner with mixed cultures of methanotrophs. The method also preferably uses periodic biomass-wasting (PHA harvesting) at the end of the carbon feed phase, gradually lengthening the time period of carbon deprivation phase to create a penalty for rapid PHA degradation and incentive for PHA accumulation. Also, bacterial enrichment cultures may be introduced periodically. The PHA-accumulating bacteria are preferably grown on common anaerobic degradation products, specifically volatile fatty acids, such as acetate and propionate, and methane gas. The PHA has useful applications in bioplastics and other products.

Bacterial Poly(Hydroxy Alkanoate) Polymer And Natural Fiber Composites

US Patent:
20080160567, Jul 3, 2008
Filed:
Dec 12, 2007
Appl. No.:
12/002001
Inventors:
Sarah L. Billington - Palo Alto CA, US
Craig S. Criddle - Cupertino CA, US
Curtis W. Frank - Menlo Park CA, US
Margaret C. Morse - Stanford CA, US
Sarah J. Christian - Stanford CA, US
Allison J. Pieja - Stanford CA, US
International Classification:
C12P 39/00
C12P 1/04
US Classification:
435 42, 435170
Abstract:
A biocomposite is produced from natural fiber fabrics embedded in a matrix of biosynthetic polyhydroxy-alkanoate (PHA) polymers. The PHA is synthesized using aerobic microbial biosynthesis using mixed bacterial cultures and a feedstock containing anaerobic degradation products such as methane and volatile fatty acids derived from microbial biodegradation of organic waste materials, which may include waste biocomposites. Monomers may be added to the synthesized PHA polymer to control mechanical properties of the resulting biocomposite. The natural fibers and/or PHA may be pretreated using various techniques to improve the bond between the fibers and the PHA resin matrix and water absorption resistance of the fibers. The composite may be a laminate of treated and untreated fabric layers, or differently treated layers, to achieve good in-service performance as well as rapid and/or optimal biogas production when taken out of service and put in an anaerobic environment to degrade.

Use Of Hydroxyalkanoic Acids As Substrates For Production Of Poly-Hydroxyalkanoates By Methane-Oxidizing Bacteria

View page
US Patent:
20110159556, Jun 30, 2011
Filed:
Dec 8, 2010
Appl. No.:
12/928323
Inventors:
Allison J. Pieja - Menlo Park CA, US
Eric R. Sundstrom - Menlo Park CA, US
Perry L. McCarty - Stanford CA, US
Craig S. Criddle - Redwood City CA, US
International Classification:
C12P 7/62
US Classification:
435135
Abstract:
A method of biosynthesis of polyhydroxyalkanoates (PHA) is provided that includes providing a type II methanotrophic bacteria, and disposing the type II methanotrophic bacteria in an unbalanced growth condition, where the unbalanced growth condition includes a nutrient-deficient media and a hydroxyalkanoic acid, and where the nutrient-deficient media has an absence of an essential nutrient required for cell replication of the type II methanotrophic bacteria.

High Productivity Methane Fermentation Processes

View page
US Patent:
20200181659, Jun 11, 2020
Filed:
May 18, 2018
Appl. No.:
16/614673
Inventors:
- Oakland CA, US
Margaret Catherine Morse - Piedmont CA, US
Allison J. Pieja - Santa Cruz CA, US
International Classification:
C12P 7/62
C12F 3/02
Abstract:
Processes are provided for enhancing the productivity of fermenters during the metabolic conversion of methane-containing gases to products containing polyhydroxyalkanoate, which products can be used to make, for instance, animal feed or biodegradable, polymeric articles. The processes involve one or both of attenuating the heat generated to grow a population of microorganisms and removal of heat during the fermentation by removal of carbon dioxide.
