The disclosure provides compositions and methods for growing programmable enzyme-functionalized and sense-and-response bacterial cellulose living materials with engineered microbial co-cultures.

The present invention relates to a composition or combination for the production of butanol and isopropanol, comprising an acetone-butanol-ethanol (ABE)-producing Clostridium strain and a genetically engineered B. subtilis strain, wherein said genetically engineered B. subtilis strain has been transformed by at least one polynucleotide molecule; the at least one polynucleotide molecule comprising a secondary alcohol dehydrogenase gene operably linked to at least one promoter. The invention also relates to methods of producing butanol and isopropanol in a co-culture, methods of producing butyrate, isopropanol and butanol in a co-culture and methods of producing esters.

The present disclosure provides methods and materials for the cultivation and/or propagation of a photosynthetic organism. Such methods may comprise the use of a lamp assembly that comprises a plurality of circuit boards, each comprising at least three edges, arranged in a substantially spherical shape defining an interior lamp assembly volume, wherein the plurality of circuit boards comprise a first planar surface in contact with the interior lamp assembly volume and an opposing second planar surface comprising light emitting diodes (LEDs); and a barrier that surrounds the plurality of circuit boards forming the substantially spherical shape.

Unique carbon dioxide or lignocellulosic substrate is prepared and used to produce biosurfactants, based on different types of microorganism fermenting strains, using carbon dioxide or lignocellulose-based raw materials as the primary feedstock, subsequently utilizing a fermentation process to synthesize different structures of biosurfactants. This is a two-phase reaction where phase-one creates the feedstock for the phase-two reactions. The fermentation broth resulting from the phase-two reaction is the crude biosurfactant; it uses glycolipid or lipopeptide biosurfactant as the main component. The broth is then refined by filtration, then concentrated, and further purified to obtain the pure biosurfactant material. The biosurfactant of the present disclosure can be applied to industries such as petroleum, food or agriculture, daily chemicals, industrial chemicals, environmental protection, and medicine.

Described herein are methods, microbial cell lines, and media used in co-culture to augment propionic acid production using an optimized fermentation medium and methods for increasing propionic acid yield, e.g., by co-culturing Lacticbacillus Casei and high-acid tolerant A. Acidipropionici.

A system and method for the production of microbial consortiums and by-product material is provided. A physical containment system comprising phase spaces arranged in a discrete order to favor specific biological reactions is also provided. Phase profiles and phase data sets include the pre-determined physical and biological parameters for the phase space transitions. Movement of material from one phase to the next is hydraulically balanced enabling working fluid to continuously move in a fixed direction and rate of flow. Continuous monitoring of phase profiles and phase data sets provide feedback to the system enabling alteration of the conditions in the system to control reactions therein.
