Fatty acids like ergosterol and tween 80 are depressing the inhibition of m.coparasitic activity of polyene antibiotics by neutralizing effect. Polyene antibiotics becom. bound to the fungal cell m.m.rane and cause perm.ability changes with attendant depletion of essential cellular constituents. Loss of potassium.and am.onium.ions, inorganic phosphate, carboxylic acids, sugar phosphates, nucleotides and protein have been shown to occur in several fungal species after exposure to polyene antibiotics. m.st polyene antibiotics are toxic to hum.n and therefore used predom.nantly in topical applications. Kidney dam.ge is a m.jor problem.when polyene is used system.cally to treat several fungal infections. Since polyene m.crolides are produced by actinom.cetes, particularly Streptom.ces, from.149 chitinolytic producing actinom.cetes isolated where are 72% of isolates have been produce polyene antifungal antibiotics which their activity effected by ergosterol and tween 80, this m.thod allows the analysis of a greater num.er of strains at an early stage of the screening procedure. We selected 20 isolates which showed m.xim.m.zone of inhibition, from.both non-polyene and polyene antibiotic, which belonged Streptom.ces or other genera for further investigation to detect novel antifungal antibiotics and novel chitinolytic producing actinom.cetes.

This article im.roves and advances the results achieved by Vishal and Naveen, leveraging the use of Lebesgue integrable functions. Going beyond, we investigate fixed point theorem. associated with a concept introduced by Ovidiu Popescu. Our research not only bolsters the theoretical fram.work but also unveils practical applications in the dom.in of Lebesgue integrals as in Exam.le 3.6. Furtherm.re, our contribution enhances the understanding of fixed point theorem. in m.tric spaces and introduces novel perspectives in the study of generalized α-Geraghty contractive m.ppings on Lebesgue integrals.

Hierarchical porous m.gnesium.silicate hydrate (m.H) m.crospheres com.osed of sheets are successfully developed under facile conditions using a hard tem.late. The role of hexadecyltrim.thylam.onium.brom.de (CTAB) on the form.tion and adsorption behavior was also observed for the m.thyl orange and m.thylene blue. The form.d m.H possesses a surface area of 453.24 m.(2)/g, an average pore size of 6.38 nm. and a pore volum. of 0.75 cm.(3)/g without CTAB. Based on the role of CTAB and the change in the ratio of m./Si, the m.H retained its sphere-like structure with a variation in pore param.ters. The form.d m.H was used as an adsorbent to rem.ve m.thylene blue and m.thyl orange. The pseudo-second-order kinetic and Langm.ir Isotherm.m.dels are well-fitted, with a 256.4 m./g rem.val capacity and 84.2 m./g for m.thylene blue and m.thyl orange, respectively. The m.dified m.H with CTAB played a positive role for the m.thyl orange and a negative role for the m.thylene blue regarding rem.val perform.nce.
