The screening of natural products in the quest for new antimicrobial and antifungal agents has become the need of the hour in order to combat drug-resistant pathogenic microbes.The aim was to evaluate the antibacterial and antifungal activities of Lavandula angustifolia and Thymus vulgaris essential oils (EOs).The antimicrobial activity was tested on Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus using agar disc diffusion and the antifungal screening was done in the same way against Candida albicans. The Thymus Vulgaris EO collected from Oran was very active against Staphylococcus aureus and Candida albicans. Lavandula angustifolia EO collected from Oran was extremely active against Pseudomonas aeruginosa and Candida albicans, Candida albicans was the most sensitive to the essential oils. Essential oils of L. angustifolia and T. vulgaris are highly effective natural antibacterial and antifungal agents that can be used to treat infections and food poisoning.

: Transfer banana plantlet from in vitro to ex vitro conditions is essential prerequisite in micropropagation. In vitro grown plantlets are unable to cope with soil environment. To avoid these challenges, the plant must be acclimatized according to a protocol that takes into account the economics of the plant concerned. Banana shoot culture was established on MS medium supplemented with 5 mg/l BAP and 30 g/l sucrose. Shoot cuttings were subjected for in vitro root formation on half strength MS medium containing 1 mg/l IBA. Plantlets were acclimatized under tissue culture room conditions where they were able to repair their physiological disorders and cope ex vitro conditions. Disorder repair processes were better if plantlets were treated with chitosan. When chitosan was used, efficiency of acclimatization increased during all acclimatization periods due to the increase in plant growth parameters, water content and ROS scavenging through the increase in activities of antioxidant enzymes such as superoxide dismutase and peroxidase. To save time and costs, root formation and acclimatization were combined in one step under transparent plastic bags (relative humidity 87%) in tissue culture room (25 o C) using ex vitro-hydroponic or soil-root formation procedure. Survival frequency was 100% when root formation was induced using 1 mg/l IBA and relative humidity was gradually decreased. Plantlets were transplanted in soil without application of in vitro or ex vitro root formation procedures died in five days.

Sir, The recent approval of the Forest (Conservation) Amendment Bill, 2023, by the Indian Parliament has raised numerous concerns among environmentalists, scholars, and indigenous communities. Although the Bill claims to champion conservation in its introduction, it ironically opens the door to potential harm to India’s precious forests. The Forest (Conservation) Amendment Bill, 2023, appears to have commendable objectives. Its introduction praises the immense importance of forests, highlighting their crucial role in sustaining ecological balance and safeguarding biodiversity for current and future generations. The Bill sets ambitious targets, like establishing a carbon sink capable of absorbing 2.5 to 3.0 billion tons of CO2 by 2030 and improving the lives of communities reliant on forests [1]. On initial inspection, the Bill seems to promise a brighter, greener future for India. carbon sink capable of absorbing 2.5 to 3.0 billion tons of CO2 by 2030 Yet, a closer examination of the Bill’s provisions paints a different picture. Although the introduction promotes conservation and sustainable growth, later sections complicate this vision. The Bill allows for the repurposing of forest lands for various non-forest activities, such as infrastructure projects, mining, and industry. This contradicts the core conservation values it initially advocates [1]. The Bill specifies forest lands as only those recognised under the Indian Forest Act, 1927, and those documented as forests in government records after 25 October 1980. It also excludes forest lands of up to 0.10 hectares near rail lines or public roads meant for public facilities, as well as areas within 100 kilometres of international borders or key zones like the Line of Control or Line of Actual Control [1]. The Bill includes provisions to expedite strategic and security-centric projects vital to the nation, particularly in border regions and areas impacted by Left Wing Extremism. It grants the central government the discretion to repurpose forest lands for various uses, including zoos, safaris, eco-tourism sites, communication hubs, and check-posts, among other purposes they deem necessary. Furthermore, the Central Government has the right to guide any entity within the Central Government, State Government, or Union Territory Administration regarding the Act’s enforcement [1]. The Bill’s provisions pose a threat to our already diminishing forests. The government’s narrow definition of forest land in this Bill is alarming. By recognising only lands designated as forests under the Indian Forest Act, 1927, and those listed as forests in government records after 25 October 1980, it overlooks a significant portion of unrecorded and community forests. This approach risks repurposing lands not labelled as ‘forest’ in official records, making them susceptible to depletion. This redefinition contradicts the Supreme Court’s landmark decision in the case of T.N. Godavarman INTERNATIONAL JOURNAL OF ENVIRONME
