The disclosure provides methods using mixed substrate cofeeding for bioproduct synthesis, which enables faster, more efficient, and higher yield carbon conversion in various organisms.

The invention relates to a method for the production of a carboxylic acid from a primary alcohol, said method comprising: a first step of growing a strain of bacterium of the genus Acetobacter capable of selectively oxidizing said alcohol into said carboxylic acid, in an appropriate growth medium comprising glycerol as carbon source, until said bacterium reaches a late exponential growth phase; then a selective oxidation step comprising aerobically culturing said bacterium in a bioconversion reactor containing an appropriate liquid bioconversion medium containing said alcohol and glycerol, for a sufficient time to oxidize said alcohol into said carboxylic acid.

A method for controlled production of glyceric acid includes, during the glyceric acid fermentation process, real-time online monitoring of at least one of the respiratory quotient and redox potential in the fermentation liquid as well as the fermentation process specific growth rate, and controlling their values within the following ranges: 0.1˜1.5 for respiratory quotient, −300˜50 mV for redox potential, 0.05˜0.8 for specific growth rate. Process parameters for this method are controlled within predetermined ranges by online monitoring at least one of respiratory quotient (RQ) and redox potential as well as the specific growth rate in the fermentation process, thereby meeting the growth requirements of bacteria, effectively promoting the glycerol metabolism and synthesis and improving the conversion rate.

The present invention provides for a bio-nematocide for repairing damage to wood and related cellulosic products caused by nematodes.

An insecticidal composition wherein the composition has an insecticidal effect based a modification of the bacteria of the genus gluconacetobacter. The Insecticidal effect show activity against Green peach aphid (Myzus persicae (Sulzer)); Western flower thrips (Frankliniella occidentalis) on peaches and Citrus woolly whitefly (Aleurothrixus floccosus) on citrus.

Methods, compositions, systems and kits relating to processing of cassava bagasse into bacterial feedstock, such as bacterial feedstock suitable for nanocellulose production, are disclosed. Cassava bagasse may be contacted with an acid catalyst or an enzymatic catalyst to produce a hydrolysate, which can be used to form a pre-fermentation medium. Incubation of the pre-fermentation medium with a first population of microorganisms yields a supernatant enriched in reducing sugars, which may be used to form a culture medium which can be used to support growth of a second population of microorganisms to form the nanocellulose.

A method for inoculating a plant with a nitrogen-fixing bacteria such as Gluconacetobacter diazotrophicus, said method comprising administering the nitrogen-fixing bacteria to a wound of a growing plant, for example to recently cut grass. Inoculation in this manner leads to enhanced growth characteristics including increased greenness of grass. Novel compositions suitable for use in the method are also described and claimed, together with kits for producing these.

Nowadays consumers are looking for “natural” food ingredients for keeping them healthy and fit in all foods. “An Organic Natural Microbial Inhibitor” is an organic antimicrobial ingredient that is synthesized from the fermentation of natural raw materials including rice flour, wheat hydrolysate and corn steep liquor. An amount of 0.1 to 1.5% during preservation of different food products like pickles, salads, beverages, and meat etc., keeps the food free from the microbial contaminations, increases flavor, and meat tenderness. It is produced through co-fermentation of Acetobacter aceti and Lactobacillus delbrueckii that are modified by way of strain improvement through medium optimization experiments. The major ingredients of the product include combination of naturally produced organic acids like acetic, lactic and propionic acids in addition to other acids in trace amounts in liquid form and also in powdered form. These are in combination responsible for the antimicrobial property with simultaneous flavor enhancement.

Microbial cell lines suitable for industrial-scale production of organic acids and methods of making and isolating such cell lines.

Disclosed is an application of a hydrophobic phthalocyanine as a heterogeneous catalyst in oxidizing phenol wastewater by hydrogen peroxide. A hydrophobic silane is decorated on a bacterial cellulose-metal phthalocyanine heterogeneous catalyst to obtain a hydrophobic phthalocyanine heterogeneous catalyst; during the catalytic degradation of phenols, the obtained catalyst is capable of adjusting a concentration of hydrogen peroxide oxidant around the catalyst. A preparation method of the hydrophobic phthalocyanine comprises: 1. preparing a mixed solution of a bacterial cellulose medium containing metal phthalocyanine; 2. adding acetic acid bacterium into the mixed solution obtained in step 1 for biological culture; 3. heating the product obtained in step 2, and taking out a solid for cleaning and drying; 4. preparing a hydrophobic silane solution; and 5. immersing the product obtained in step 3 into the solution obtained in step 4, and taking out a solid after reaction for cleaning and drying.
