Biofilm Matrix

To study the composition of a biofilm a previous extraction method is required to separate cells from the matrix. There are several methods reported in the literature; however they are not efficient or promote leakage of intracellular material. In this work several extraction methods were assayed in mixed culture and pure culture biofilms and their efficiency was evaluated by the amount of organic carbon, proteins and intracellular material extracted. The results showed that the extraction with glutaraldehyde 3% (w/v) was the most suitable method, extracting great amounts of organic carbon without promoting cell lysis or permeabilization. Glutaraldehyde is a bifunctional reagent that binds to cell walls avoiding their permeabilization and the biofilm matrix is solubilized in the solution.

Abstract An investigation of a major difference in a special sample showed the reason for the potassium value differences in many routine fertilizer samples. Lower K2O values by AOAC official carbonate extraction method 2.079(a) as compared with AOAC official oxalate extraction method 2.070(a) were found consistently for 17 typical mixed fertilizer samples investigated. An average lower absolute difference of 0.4% K2O was found on the typical mixed fertilizers by carbonate extraction. Studies show that this difference is associated with the impurities in fertilizer grade phosphate raw materials, particularly the varying solubility of the (Fe,Al) (NH4,K,H) phosphates.

ABSTRACT Introduction Laghupanchamula is a compound formulation prepared by combinations of roots of five herbs. Two variants of Laghupanchamula have been described in Ayurvedic classics where beside four common herbs fifth one is either Gokshura (Tribulus terrestris L.) or Eranda (Ricinus communis L.). The objective of the study is to make comparison between two variants of Laghupanchmula with respect to important group of phytochemicals and antioxidant activity to corroborate the science behind their therapeutic utility. Materials and methods Standard methods have been followed for quantitative determination of total quantity of phenols, tannins, flavonoids, and flavonols, and in vitro antioxidant activity in variants of Laghupanchmula formulations. Qualitative high-performance liquid chromatography (HPLC) analysis has also been performed to establish presence/absence of important chemical constituents in formulations. Results Additional quantity of phenols, tannins, flavonoids, and flavonols has been observed in Laghupanchamula variant containing Eranda than the variant containing Gokshura. Greater antioxidant activity has also been found in formulation containing Eranda. The HPLC analysis revealed the presence of shikimic acid, gallic acid, catechin in both formulations, but rutin has been found only in formulation containing Eranda. Conclusion From the results of experiments it has been observed that the formulation containing Eranda has more antioxidant activity as it contains more quantities of phenol, tannins, flavonoids, and flavonols than the formulation containing Gokshura.
