A new synthesis of 4‐aminooxazoles from α‐oxonitriles
(1988) Ram Lakhan; Ram Lakhan Singh
A general synthesis is described for the preparation of 4‐amino‐2,5‐disubstituted oxazoles 2. The interaction of α‐oxonitriles 1 with equimolecular amounts of aromatic or aliphatic aldehydes, and excess of anhydrous ammonium acetate in glacial acetic acid at 110–120° for 3–6 hours gives 2 in 40–65% yields. A plausible reaction mechanism for the formation of 2 is also suggested. Copyright © 1988 Journal of Heterocyclic Chemistry

Fungal Cellulases Production for Biodegradation of Agriculture Waste
(Springer, 2018) Neha Srivastava; Manish Srivastava; Ambepu Manikanta; P.W. Ramteke; Ram Lakhan Singh; P.K. Mishra; S.N. Upadhyay
Cellulases have several existing and potential applications in various industries including biofuel, pulp and paper, detergent, juice, and textile. Different enzyme components found in the cellulase system can effectively depolymerize the cellulose into monomeric sugars. Fungi are regarded as an ideal candidate to produce a complete cellulase system. Cellulase production via solid-state fermentation (SSF) using fungi is one of the most desirable and cost-effective routes. The present chapter provides an outline on the major steps of fungal cellulase production using SSF. This chapter presents a concise account of fungal cellulases as well as their production and key role in bioconversion of lignocellulosic waste. Various aspects of fungal cellulase production using the agriculture wastes and their components have been discussed. Additionally, potential fungal sources of cellulase along with effective bioconversion of agricultural biomass are also summarized. © Springer Nature Singapore Pte Ltd. 2018.
Introduction: Nanobiotechnology for the livestock industry
(Elsevier, 2023) Kshitij RB Singh; Vanya Nayak; Jay Singh; Ram Lakhan Singh; Ravindra Pratap Singh
Nanotechnology started gaining significant attention in the late 1990s and has now found its utilities in almost every domain such as biomedical, veterinary, pharmaceutical, agricultural, environmental, sensor, electronics, aeronautics, etc. However, these nanomaterials possessed certain disadvantages such as high toxicity, expensive techniques, and low biocompatibility, limiting their broad applications. Therefore, nanobiotechnology was found to be a suitably advanced technique that utilized biotechnological methods to enhance biocompatibility and decrease the cytotoxicity of nanomaterials. Nanobiotechnology uses bionanomaterials, which are synthesized from different biological materials, and therefore showed less toxicity, high biocompatibility and was economical. Further, nanobiotechnology found its broad-spectrum role in maintaining livestock and livestock-based products such as packaging, drug and gene delivery, therapeutics, diagnostics, genetic engineering, etc. It has been suggested that good livestock health can result in increasing public health and increase the country's economy. Therefore, this chapter tends to highlight the various utilities of nanobiotechnology in maintaining the health of livestock, producing transgenic animal products, and increasing the market value of veterinary products. © 2023 Elsevier Inc.

Synthesis and Evaluation of 2-Imino-3-(4-arylthiazol-2-yl)-4-thiazolidinones and Their 5-Arylidene Derivatives as Potential Fungicides
(1991) Ram Lakhan; Ram Lakhan Singh
A series of new 2-imino-3-(4-arylthiazol-2-yl)-4-thiazolidinones and their 5-arylidene derivatives have been synthesized from 2-amino-4-arylthiazoles as starting materials. The reaction mechanism has also been critically examined. Of all the synthetic compounds tested against Trichoderma harzianum and Curvularia lunata, two of them, namely 2-imino-3-(4-p-chlorophenylthiazol-2-yl)-4-thiazolidinone and 5-benzylidine-2-imino-3-(4-p-tolylthiazol-2-yl)-4-thiazolidinone, exhibited the most potent fungicidal effect. © 1991, American Chemical Society.
