Abstract: Methods and systems for automated counting and classifying microorganisms. A method disclosed herein includes receiving and analyzing quality of at least one input media of at least one incubated dish used for growth of the colonies of the microorganisms. The method further includes detecting the colonies of the microorganisms in a growth medium disposed on the dish if the received at least one media is a good quality media, wherein the detected colonies include at least one of individual colonies and grouped colonies. The method further includes segregating the grouped colonies into the individual colonies. The method further includes classifying the individual colonies into at least one species of the microorganisms. The method further includes counting the colonies of each species.

Abstract: The present invention discloses a novel process for purification of trans-4-methyl cyclohexylamine HCl and 4[-2-(3-Ethyl-4-methyl-2-carbonyl pyrrolidine amido) ethyl] benzene sulfonamide used in the synthesis of 3-Ethyl-2,5-dihydro-4-methyl-N-[2-[4-[[[[(trans-4-methyl cyclohexyl)amino]carbonyl]amino]sulfonyl]phenyl]ethyl]-2-oxo-1H-pyrrole-1-carboxamide (I), popularly known as Glimepiride. The present invention also discloses a novel purification of Glimepiride usingS methanolic ammonia and glacial acetic acid to obtain highly pure Glimepiride Form I (I) having the undesired cis isomer below 0.15%. Glimepiride (I) is useful in the treatment of diabetes mellitus.

Abstract: A process for the preparation of 5-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]phenyl methyl]thiazolidine-2,4-dione maleate (the compound of Formula VI) comprising the steps of Coupling 2-[N-methyl-N-(2-pyridyl)amino]ethanol (the compound of Formula I) and 4-fluorobenzaldehyde (the compound of Formula II) in N,N-dimethylformamide, isolating the coupled product 4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]benzaldehyde (the compound of Formula III), converting said isolated benzaldehyde compound of formula III) to 5-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]benzylidene]thiazolidine-2,4-dione (the compound of Formula IV) and purifying the same, reducing 5-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]benzylidene]thiazolidine-2,4-dione, by a novel reduction method for making 5-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]phenyl methyl]thiazolidine-2,4-dione (the compound of Formula V).
