A direct chemical lysis composition includes an assay compatible buffer composition and an assay compatible surfactant. When combined with a specimen storage composition, such compositions prevent undesired modifications to nucleic acid and proteins lysed from cells in the biological sample. Assays of samples from such compositions do not require expensive and time-consuming steps such as centrifugation and prolonged high temperature processing. The direct chemical lysis composition of the present invention permits direct nucleic acid extraction from the cells in the biological sample without the need to decant off the transport media or otherwise exchange the transport media with assay compatible buffers. There is no need to combine the sample with proteinase K or another enzyme to extract nucleic acids from the cells. A method for lysing cells to obtain target nucleic acid for assay and a kit for combining the direct chemical lysis composition with a sample are also contemplated.

Embodiments disclose an apparatus and methods for biological sample processing enabling isolation and enrichment of microbial or pathogenic constituents from the sample. A vessel for sample containment and extraction is further disclosed for engagement with a transducer capable of efficient sample disruption and lysis. Together these components provide a convenient and inexpensive solution for rapid sample preparation compatible with downstream analysis techniques.

The present disclosure provides improved methods for bead beating and a bead beating system useful therefor. The present disclosure further provides methods of using the bead beating system to extract nucleic acids from cells containing the nucleic acids.

The present invention relates to a method for obtaining yeast proteins comprising the following steps: a) providing a yeast cream; b) exposing this yeast cream to a thermal plasmolysis at a temperature between 70 and 95° C. for a time of between 30 seconds and 4 hours; c) subjecting the whole to the activity of at least one ribonuclease and a glucanase, sequentially or simultaneously, at a temperature between 40 and 65° C. for a period of between 8 and 24 hours; and d) separating the insoluble fraction from the soluble fraction; wherein the insoluble fraction collected in step d) is taste-free, has a nucleotide content less than 3% and a true protein content of at least 72%.

A method for algae disruption includes: a thermal treatment of microalgae belonging to Heterokontophyta at a pH of 3.5 or more and 9.5 or less and a temperature of 40° C. or more and 65° C. or less; and a physical treatment of the microalgae using a high pressure dispersion apparatus, the physical treatment following the thermal treatment.
