The invention is directed to a process for producing one or more fermentation product in a multi-stage process including an inoculation reactor and at least one bioreactor. The inoculation reactor is fed a C1-containing gaseous substrate containing a reduced amount of hydrogen. The hydrogen is reduced to increase the proportion of CO in the C1-containing gaseous substrate being provided to the inoculation reactor. The inoculation reactor ferments the CO-rich C1-containing gaseous substrate and produces an inoculum, which is fed to at least one bioreactor. The bioreactor receives the C1-containing gaseous substrate, which may or may not contain reduced amounts of hydrogen, to produce one or more fermentation product. By providing a CO-rich C1-containing gaseous substrate to the inoculation reactor, both the inoculation reactor and the subsequent bioreactor(s), are able to have increased stability and product selectivity.

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

The present disclosure is directed to microorganisms that are genetically modified to express at least one exogenous enzyme involved in N-acetylglucosamine uptake and metabolism. Methods for the production of an exopolysaccharide are also disclosed. The exopolysaccharide comprises N-acetylglucosamine and D-glucose and may be used as a bioresorbable implant for soft tissue repair, replacement, or augmentation.

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.

There is described a method for producing polymeric 3-hydroxypropionamide (3HP amide), the method comprising: culturing an Acetobacter lovaniensis-bacterium in a growth medium containing phosphate and ammonium, wherein culturing of the bacterium produces polymeric 3HP amide. The polymeric 3HP amide may then be hydrolysed to 3HP amide or converted to other compounds of interest.

The present disclosure is directed to microorganisms that are genetically modified to express at least one exogenous enzyme involved in D-glucosamine uptake and metabolism. Methods for the production of an exopolysaccharide are also disclosed. The exopolysaccharide comprises N-acetylglucosamine and D-glucose and may be used as a bioresorbable implant for soft tissue repair, replacement, or augmentation.

The present invention relates to a novel strain of Acetobacter malorum, compositions comprising said strain and to methods for the preparation of such compositions.

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

Disclosed is a method for treating phenol wastewater. The method includes the following step: adding a hydrophobic phthalocyanine as a catalyst, and H.sub.2O.sub.2 as an oxidant into the phenol wastewater. The hydrophobic phthalocyanine is obtained by decorating a hydrophobic group on a bacterial cellulose-metal phthalocyanine with a silane coupling agent; the bacterial cellulose-metal phthalocyanine is obtained by mixing a metal phthalocyanine into a bacterial cellulose medium, biologically culturing with an acetic acid bacterium, and then heating and reducing the mixture; and the metal phthalocyanine is nitro-sulfonic metal phthalocyanine.

Provided is a use of fibers formed of ?-1-4-glucan in manufacturing a composition for preventing or treating diarrhea, constipation or irritable bowel syndrome, wherein the fibers have a diameter between 15 nm to 35 nm and a mean length of between 1.5 ?m and 3.5 ?m. Also provided is a method for preventing or treating diarrhea, constipation or irritable bowel syndrome with the fibers formed of ?-1-4-glucan.
