Lactic acid is the meekest hydroxyl carboxylic acid (2-hydroxy propionic acid) which is a colorless, odorless, hygroscopic, organic compound with no toxic effect, a very inevitable and versatile chemical used in the Food, cosmetics, textile, and pharmaceutical industries for very long years. Lactic acid was produced as non-racemic when specific microbial strains were used; therefore, microbial fermentation gained more attention. Albeit the substratum used for the microbial fermentation price is much exorbitant. Wherefore, identifying the best and cheap substrates is a bottleneck for the scientific community. Sugarcane molasses is the best source of components for microbial growth and cheap raw material for Lactic acid fermentation. This study produced sustainable lactic acid from sugarcane molasses by the Bacillus amyloliquefaciens J2V2AA strain with a higher production of 178 gm/L/24 h. The produced lactic acid was characterized and analyzed by UV-Visible Spectrum, FTIR Spectrum, TLC, and HPLC.

The genus Impatiens Linnaeus (1753: 937) contains a wealth of untapped treasures for gardeners and it is one of the mega diverse genera of angiosperms comprise about 1059 species (POWO 2020). According to the recent estimate, India is known to have 250 species and majority of them occur in Eastern Himalayas (Gogoi et al. 2018) and the Western Ghats (Bhaskar 2012). Tamil Nadu is one of the plant-rich states in the country and with 5674 angiosperm taxa, it ranks first among all the states in the country (Lakshminarasimhan et al. 2014).

The genus Potamogeton Linnaeus (1753: 126) is commonly called as pond weeds and they are the largest genera in the family Potamogetonaceae with about 88 species (POWO 2021). Furthermore the genus is noted for its high phenotypic plasticity and frequent hybridization that prompts impressive challenges in the delimitation and identification of species (Kaplan et al. 2009, 2013). A few instances of the homonymy among living and fossil monocots have been as of late settled by various workers (Turner 2014, Doweld 2016, 2018, Govaerts 2018, Kottaimuthu & Basu 2020). Recently we found that the extant hybrid Potamogeton × mirabilis Kaplan et al. (2009: 630) is an illegitimate later homonym according to Art.53.1. of ICN (Turland et al. 2018) because the name was already used by Kutuzkina (1957) to a fossil-species from Kyrgyzstan (formerly USSR). Hence a new replacement name is proposed for this nothospecies.
