Abstract
The invention relates to a method for the provision of silicate to a culture media. In particular the invention relates to a method of mitigating silicate precipitation and/or gel formation when providing silicate to a culture media having a pH of about 7-9.
Claims21
1-39. (canceled)
A method of mitigating silicate precipitation and/or gel formation when providing silicate to a culture media having a pH of about 7-9 wherein the method comprises:
- addition of an aqueous silicate solution to the culture media, wherein the aqueous silicate solution is rapidly dispersed into the culture media on addition to the culture media.
A method of mitigating silicate precipitation and/or gel formation when providing silicate to a culture media having a pH of about 7-9 wherein the method comprises:
- addition of an aqueous silicate solution to the culture media,
- wherein the culture media is agitated, and
- wherein the first contact of the aqueous silicate solution with the culture media is at or proximate an area of high or maximal agitation of the culture.
A method of growing microorganisms in culture media having a pH of about 7-9, the method including the steps of:
- (i) agitating the culture media to substantially evenly distribute the microbial cells in the media;
- (ii) adding aqueous silicate solution to the culture media at or proximate to an area of high or maximal agitation in the culture media.
A culture vessel for growing microorganisms within a media, the vessel comprising,
- a tank capable of containing culture media;
- a conduit for delivering an aqueous silicate solution to the culture media;
- wherein the conduit is extendable or extends into the tank to terminate at either:
- (i) an area above the surface of the culture media when contained in the tank wherein the area avoids contact of the silicate solution with tank components prior to contact with the culture media;
- or
- (ii) an area below the surface of the culture media when contained in the tank.
