摘要:
Microfibrillated cellulose, derived from vegetables or wood, can be used to provide a liquid composition which is compatible with a broad range of ingredients suitable for consumer applications, including enzymes, while still providing good structuring of the liquid composition, without affecting ease of pour.

The present compositions and methods relate to a beta-mannanase from Actinosynnema mirum, polynucleotides encoding the beta-mannanase, and methods of make and/or use thereof. Formulations containing the beta-mannanase are suitable for use in hydrolyzing lignocellulosic biomass substrates, especially those comprising a measurable level of galactoglucomannan (GGM) and/or glucomannan (GM).

摘要:
An enzyme exhibiting mannanase activity, which enzyme i) is immunologically reactive with an antibody raised against a purified mannanase derived from Aspergillus aculeatus, CBS 101.43; ii) is encoded by the DNA sequence shown in SEQ ID No. 1 or an analogue of said sequence, and/or; iii) comprises the amino acid sequence shown in SEQ ID No. 2 or a sequence being at least 70 % homologous thereto. The enzyme may be used for various purposes for which degradation or modification of a plant or algal cell wall material is desirable.
摘要:
The new formula, of which an application has been submitted for exclusive protection by means of a patent, is a mixture of sugar sucrose and invertase, with or without the addition of water, in which the 3 elements may be added in variable proportions, remaining, however, within an established threshold. This formula has been created for the purpose of providing usable nutrition for honey bees and other animal species, since it is transformed over time, partially and gradually, into glucose and fructose. The innovative aspect of this foodstuff formula is the use of invertase enzyme for obtaining nutritious sugar compounds for bee- and insect-keeping and the breeding of animals (with the exception of human beings). The formula composed of sucrose with invertase, with or without water, has been tested to improve the biological activity of honey bees, other species of insect and animals of other families, thanks to its high nutritional potential, usability and appetizing properties. It can also be used as carrier for other nutrients or nutritional components or to incorporate active principles for health purposes or for the biological stimulation of various animal species, which may take advantage of the consumption of sugar, or also to stimulate reproduction, used 'as is' or as a carrier for other nutrients or components or active principles . This formula can also be used to help honey bees overcome difficult periods caused by adverse environmental or climatic conditions.
